Institute o f Geological Sciences, Jagiellonian University, Oleandry 2a: 30-063 Kraków, Poland Uchman, A., 1996. Taxonomy and ethology of flysch trace fossils: revision of the Marian Książkiewicz collection and studies of complimentary material. Ann. Soc. Geol. Polon., 68: 105-218.

A bstract: Ichnotaxonomy o f 1,840 of flysch trace fossil specimens from the Książkiewicz collection is revised.

The specimens derive from diverse Tithonian-Miocene flysch deposits of the Polish Carpathians. Their ichno­

taxonomy, based on morphology, was published by Książkiewicz in 1997. In the revision presented in this publication, the ichnotaxonomic subdivisions are based on type o f behaviour represented by the considered trace fossil. As a result, several diagnoses are changed and several ichnospecies ascribed to other ichnogenera.

Ichnogenera Hormosiroidea, Saerichnites, IParahaentzschelinia, Halopoa, Nereites, Beaconites, Cladichnus, Protovirgularia, Ubinia and Oscillorhaphe are used the first time in the Polish Carpathians. The ichnogenera Pararusophycus, Rhabdoglyphus, Fucusopsis, Traucumichnis, Sabularia, Granularia, Bostricophyton, Halyme- nidium, Buthotrephis, Tubuliclmium, Tuberculichnus, Helminthoida, Muensteria, Keckia, and Taphrhelminthoida are not recommended for further use. The new ichnogenus Belocosmorhaphe n. igen. and the new ichnospecies name Cosmorhaphe carpathica nom. nov. are proposed. Ichnotaxa Trichichnus linearis Frey, Imponoglyphus torquendus Vialov, Palaeophycus tubularis Hall, Chondrites Irecurvus (Brongniart) and Arenituba isp. are distinguished for the first time in the Carpathian flysch on the base o f Książkiewicz material.

A bstrakt: 1840 okazów fliszowych skamieniałości śladowych z kolekcji Książkiewicza poddano ichnotaksono- micznej rewizji. Okazy te pochodzą z różnych tytońsko-mioceńskich utworów fliszowych Karpat polskich. Ich ichnotaksonomia, oparta na morfologii, była przedstawiona przez Książkiewicza w 1977 roku. W rewizji przedsta­

wionej w niniejszej publikacji, wydzielenia ichnotaksonomiczne oparto na typie behawioru reprezentowanego przez daną skamieniałość śladową. W rezultacie, zmieniono szereg diagnoz. Wiele ichnogatunków zaliczono do innych niż dotąd ichnorodzajów. Ichnorodzaje Hormosiroidea, Saerichnites, IParahaentzschelinia, Halopoa, Nereites, Beaconites, Cladichnus, Protovirgularia, Ubinia i Oscillorhaphe użyto po raz pierwszy w Karpatch polskich. Ichnorodzaje Pararusophycus, Rhabdoglyphus, Fucusopsis, Traucumichnis, Sabularia, Granularia, Bostricophyton, Halymenidium, Buthotrephis, Tubulichnium, Tuberculichnus, Helminthoida, Muensteria, Keckia i Taphrhelminthoida nie są rekomendowane do dalszego używania. Zaproponowano nowy ichnorodzaj Belo­

cosmorhaphe n. igen. i nową nazwę ichnogatunkową Cosmorhaphe carpathica nom. nov. Ichnotaksony Trichi­

chnus linearis Frey, Imponoglyphus torquendus Vialov, Palaeophycus tubularis Hall, Chondrites 1 recurvus (Brongniart), Arenituba isp. są wyróżnione po raz pierwszy we fliszu karpackim, w oparciu o materiał z kolekcji Książkiewicza.

Key words: Ichotaxonomy, trace fossils, flysch, Cretaceous, Paleogene, Carpathians.

AIM, MATERIAL, AND METHODS

Im precisely defined ichnotaxa are still the w eak point o f ichnology. This problem still negatively influences various applications o f trace fossils and is a hinderence in their study. The problem m ay be am eliorated by ichnotaxonom ic revisions using the application o f clearly defined principles.

Such revision o f the K siazkiew icz collection is the main aim o f this paper.

The K siazkiew icz collection, housed in the Institute o f G eological Sciences o f the Jagiellonian U niversity, Krakow (acronym U J TF), is one o f the largest flysch trace fossil col­

lections in the world. It contains 1,840 specim ens including 57 ichnogenera and 147 ichnospecies described by Ksi^z- kiew icz (1958, 1960, 1961, 1968, 1970, 1977) from alm ost 220 localities in the Polish C arpathians, from the T ith o n ian - M iocene flysch form ations. A lm ost all the specim ens w ere labelled. Each full label includes num ber o f specim en, nam e o f locality and lithostratigraphic unit, and ichnotaxonom ic detennination. A num ber o f the labels appeared to be not readable, having been dam aged because o f im proper hous­

ing. For this reason, a lot o f im portant inform ation from la­

bels was lost. As a result o f the inventory w ork connected

w ith the present revision, the first catalogue o f the speci­

m ens o f the collection was prepared, w hich com prises the inform ation from the labels and place o f housing. The col­

lection contains a few ichnotaxa, w hich w ere neither de­

scribed nor labelled, for instance T richichnus and Im pono- glyphus, w hich are included in this study. A bout a dozen specim ens are lost.

In order to resolve certain ichnotaxonom ic problem s, com plem entary m aterial was studied. This derives from the author’s collection, the collections in the N aturhistorisches H ofm useum in V ienna, the Sternberg collection in the N a ­ tional M useum in Prague, the H eer collection in the G eo­

logical Institute o f the ETH, Zurich, and the F ischer-O oster collection in the N atural H istory M useum in Bern.

Som e specim ens from the K siazkiew icz collection un­

derw ent additional preparation, and/or w ere cut and studied in polished slabs after treatm ent w ith the “ B ushinsky oil technique” (B rom ley, 1981).

(3)

The first problem is th e definition o f trace fossils. I fol­

low the idea that trace fossils are the sedim entary expres­

sions o f fossil behaviour (Seilacher, 1986). Thus, the m ost im portant questions o f ichnotaxonom y are w hat behaviour is represented by an exam in ed trace fossil and how to clearly define it, not only th e exact description o f the ap­

pearance o f the exam ined trace fossil. M orphology o f trace fossils can be strongly d ep en d an t on taphonom ic processes.

Especially, trace fossils preserv ed as sem i-reliefs are incom ­ plete bedding-plane expressions o f com m only m uch m ore com plicated three-dim ensional burrow s. The num erous dif­

ficulties encountered in reconstruction o f com plete trace fossils and in understanding o f the bahaviour they represent cannot be argum ents th at influence principles o f ichnotax­

onom y.

The other problem is th e rank o f ichnotaxonom ic divi­

sions, especially the hierarchy o f features used for diagnoses o f ichnogenera and ichnospecies. I tried to follow the idea o f Fiirsich (1974a), according to w hich im portant m orphologi­

cal features (so-called significant features) diagnostic o f ich­

nogenera are these related to distinct behaviour are diagnos­

tic o f ichnogenera. O ther features related to m inor variation o f tracem aker behaviour and to som e preservational features are regarded as diagnostic o f ichnospecies (so-called acces­

sory features). O ther features o f third-order rank, reflecting m ainly preservational aspects, m ay be used inform ally at the subichnospecies level as variations (U chm an, 1995). D ivi­

sion o f this level is not forbidden by the 1985 International Code o f Z oological N o m en clatu re (R indsberg, 1990). Ex­

am ples o f their use are given by Ekdale & Lew is (1991b) for Diplocraterion. The m ain prin cip le in the presented ichno­

taxonom y is th e application o f ichnogeneric nam es only for trace fossils representing d istinctly different fossil behav­

iour. O nly ichnogenera d iagnosed in this w ay m ay be used for further palaeoecological interpretations and com pared w ith other ichnocom m unities. A pplication o f accessory or low er-rank features at the ichnogeneric level w ould give a false picture o f behavioural diversity.

In order to recognize the fossil behaviour represented by som e trace fossils, their careful ethological interpretation is necessary. Such interpretation w as applied for instance to passively filled Palaeophycus versus actively filled Plano- lites (Pem berton & Frey, 1982). P urely m orphological clas­

sification, w ithout references to any ethological m odel and w ithout taphonom ic interpretation, seem s to be one o f the dead-ends o f ichnotaxonom y.

A nother problem o f ichnotaxonom y is classification o f trace fossils above the ichnogeneric rank (cf. Brom ley, 1996). K si^zkiew icz (1977) introduced classification o f flysch trace fossils based solely on m orphological criteria.

He distinguished ten m orphological groups, nam ely: (1) cir­

cular and elliptical, (2) sim ple, (3) branched, (4) rosetted, (5) spreite, (6) w inding, (7) spiral, (8), m eandering, (9)

(e.g., Arthrophycus, Halymenidium=Spongeliomorphd). For this reason the sim ple and branched structures are u nited in one group in this paper. In the K siqzkiew icz, classification genetically close ichnotaxa, such as Scolicia and Taphr- helminthoida (=Scolicia in this paper), belong to different groups. Thus, a classification based on rigid criteria is not satisfactory.

SYSTEMATIC PART

In order to shorten the system atic part, a num ber o f ich­

notaxa descriptions provided by K siazkiew icz (1977) that have not been changed or have been supplem ented only by new diagnoses, are om itted.

tinctly larger and display a double ring.

O rigin o f M. aggeris is not clear. A ccording to C ham ­ berlain (1971a), this is a resting or hiding trace, a fossil egg case (a body fossil), or th e u pper term ination o f a burrow.

Later, C ham berlain (1977) suggested that M. aggeris is a resting or dw elling trace pro d u ced by a ?"w orm " and th at it is probably a preservational v ariant o f Alcyonidiopsis p h a r- m aceus R ichter & Richter. H ow ever, it is difficult to find re­

lationships betw een these tw o ichnotaxa. O nly the granular surface in som e specim ens o f M. aggeris (especially in the C ham berlain’s m aterial) m ay be related to the pelletal struc­

ture o f Alcyonidiopsis. H ow ever, the m orphology o f the apex in M. aggeris has no relationship to hom ogenously fae­

cal-stuffed trace fossil o f A lcyonidiopsis. K si^zkiew icz (1977) suggested that M am m illichnis is an actinian burrow

DEPRESSION IN THE SEA-FLOOR IN CROSS-SECTION

RESULTED TRACE FOSSILS AFTER CASTING IN CROSS-SECTION

Fig. 2. General model (top) and morphological variations (be­

low) of Mammillichnis. The morphological variants depend on the shape o f the depression in the sea floor

because o f supposed radial sym m etry in C h am b erlain ’s (1971a) fig. 7J, w hich is, how ever, a draw ing o f the trace fossil m odel. Sim ilarly, C rim es e t al. (1981) referred to sup­

posed radial sym m etry o f M. aggeris in their pi. 4, fig. 9.

H ow ever, neither the K si^zkiew icz m aterial nor the speci­

m en in the photograph o f C rim es et al. (1981) display the radial patterns. The photographs and descriptions published by C ham berlain (1971a) and part o f the photographs o f C rim es e t al. (1981) show a granular surface o f the trace fos­

sils, and therefore their slightly lobate outline, w hich cannot be treated as the radial pattern. The K si^zkiew icz specim ens are m ostly sm ooth and display convex or concave apex.

Som e o f them , sim ilarly to the m aterial o f C rim es e t al.

(1981), are slightly fluted. This reveals the pre-depositional origin o f the trace fossil flange. H ow ever, it cannot be ex­

cluded that the apical knob is a term ination o f a vertical bur­

row that m ay be also active after deposition o f turbidite.

N evertheless, there is no vertical burrow structure in the pol­

ished slab o f one cross-sectioned K si^zkiew icz specim en (U J TF 1762).

In tw o cases (UJ TF 1763, 2501), the trace fossils dis­

play a bulb-like m orphology in cross-section, i.e. their di­

am eter is sm aller at the base than at the half-w ay poin t o f their height.

M ost probably, M. aggeris represents the upper part o f a thin vertical or subvertical cylindrical burrow , w hich d is­

plays a hem ispherical funnel-like u pper term ination (Fig. 2).

(5)

hesive sedim ent. In contrast, the funnel o f M. aggerisw as m ost probably produced actively by the tracem aker in cohe­

sive m ud and possibly it w o rk e d as a trap. Thus, the funnel is a record o f a unique b ehaviour and is a basis for separa­

tion o f M. aggerisfrom o ther ichnotaxa. H ow ever, it is not excluded that Mammillichnisand LaevicyclusQ uenstedt are related. N evertheless, there is so far no satisfactory explana­

tion o f Laevicyclusand th erefo re such com parison cannot be drawn. Probably, the flatter specim ens w ith deeper apical depressions, w hich resem ble Laevicyclus, are only preserva­

tional variants o f the sam e ichnotaxon. T hese specim ens can occur if the term ination o f the thin burrow in the funnel w as rim m ed by a sm all m ound (Fig. 2).

Palaeoenvironm ent: D eep-sea flysch deposits, except one occurrence in the C arboniferous deltaic deposits (Eager et al., 1985) and on eocurrence (?) in teh C am brian shallow - w ater deposits (Paczesna, 1986, 1996).

Stratigraphic range: (?)C am brian (Paczesna, 1986, 1996), O rdovician (C ham berlain, 1977), O ligocene (Ksi^z- kiewicz, 1977; A lexandrescu et al., 1993).

Bergaueria Prantl 1945

Diagnosis: C ylindrical or h e m isp h erical, vertical structures h a v ­ ing sm ooth, u n o m am en ted w a lls, c irc u la r to ellip tical in cro ss-sec­

tion; fill essen tially stru ctu reless; ro u n d ed base, w ith o r w ith o u t shallow , central depression an d radial ridges (after P em berton et al., 1988).

Remarks: Bergaueria is pro b ab ly a cubichnial o r dom ich- nial trace fossil produced by suspension-feeders (Ftirsich,

1975). These w ere pro b ab ly coelenterates, chiefly sea anem ones (e.g. Prantl, 1945, A lpert, 1973; P em berton et al., 1988) sim ilar to living Cericmthusor Edwardsia(Pem berton et a l, 1988). The present-day sea anem ones are very w idely distributed from estuaries to abyssal plains (e.g. C arney, 1981). H ow ever, in the case o f non-radiated IB. prantli K si^zkiew icz (1977) and B. hemispherica C rim es et al.

(1977) that additionally has no apical depression, the com ­ parison w ith sea-anem one burrow s should be treated with caution.

Bergaueriaoccurs in diverse facies from shallow -w ater deposits (N arbonne, 1984; C rim es & A nderson, 1985) to flysch deposits (Prantl, 1945; K si^zkiew icz, 1977; C rim es

& C rossley, 1991) from the late Precam brian (e.g. Crim es, 1987) to (?) the Eocene (K si^zkiew icz, 1977) and M iocene (U chm an, 1995).

Emended diagnosis: B ergauerians that display an irregular shape and apical, m ore or less distinct, irregular depression.

M aterial: 3 specimens (U J TF 115 (holotype), 967, 1178).

Remarks: In confrontation w ith the revised Bergaueria (Pem berton et al., 1988), the original K si^zkiew icz (1977) diagnosis o f IB. prantli is too b road and does not suffi­

ciently express differences betw een this taxon and B. perata Prantl. P em berton et al. (1988) reservedly included IB.

prantliin B. perata. This suggestion cannot be accepted. B.

perata is m ore regular, w ith steeper sides, m ore or less cir­

cular apical depression, and faint radial ridges at the apex.

T he differences have been noticed b y K si^zkiew icz (1977, p. 53). In contrast, IB. prantliis ch aracterized by an irregu­

lar outline and irregular apical depression. T herefore, it should be treated as a separate ichnospecies. H ow ever, it is not clear if this trace fossil is a real Bergaueria, w hich is typified by B. perataPrantl. It cannot be excluded th at som e specim ens are casts o f the upper term inations o f som e verti­

cal or subvertical partially filled burrow s. T herefore, the question-m ark is placed in front o f the ichnogeneric nam e.

Som e specim ens labelled by K si^zkiew icz as B. prantli are undeterm inable trace fossils (U J TF 1471).

Emended diagnosis: O blique to horizontal, cylindrical or subcylindrical structures w ith regular, perpendicular fine ribs and a tendency to plunging into bed surfaces. C om ­ m only, the trace fossils are grouped in bundles.

Remarks: Probably, the above diagnosed Arthrophycus em braces only three ichnotaxa, i.e. A. alleghanienis (H ar­

lan) and tw o ichnotaxa lum ped so far in A. strictus Ksiqz- kiew icz, w hich are separated as A. strictusK si^zkiew icz and A. tenuis(K si^zkiew icz) in this paper. O rr (1994) illustrated Arthrophycus minoricensis B ourrouilh, w hich w as origi­

nally described in an unpublished thesis. The description and illustration o f this trace fossil is not sufficient for assess­

m ent o f its diagnostic features. Arthrophycus qiongzhusien­

sis described b y Luo et al. (1994) from the C am brian o f C hina, is a hypichnial, w inding trace fossil w ith fine trans­

verse striae. A photograph o f this trace fossil suggests that the striae can be an external expression o f internal sedim ent pads typical o f Torrowangea W ebby. R elationships be­

tw een these two ichnotaxa should be explained. Z hang &

W ang (1996) described Arthrophycus hunanensisfrom Silu- rian -D ev o n ian deposits o f C hina. It is not excluded that it is a ju n io r objective synonym o f A. alleghanienis.

Arthrophycus annulatus K si^zkiew icz and Arthrophy- cus(T) dzulynskii K si^zkiew icz (K si^zkiew icz, 1977), and several other ichnotaxa are excluded from Arthrophycusas indicated in the above list.

A. alleghanienis (H arlan) is com m on in neritic silici- clastic facies o f the M iddle P alaeozoic and regarded as rep­

resenting a burrow (Sarle, 1906) o f feeding arthropods (e.g., T urner & B enton, 1983). H ow ever, Schiller (1930) tried to explain it as a tectonic structure, and B ecker & D onn (1952) regarded this ichnotaxon as an “ algal structure” . A. al­

leghanienism ay occur as linear, protrusive, flat palm ate, or deep palm ate retrusive trace fossil (S eilacher & A lidou, 1988). The palm ate specim ens have been included in Phy- codespalmatus(H all) (Seilacher, 1955, p. 386) [incorrectly spelled P. palmatum;Fillion & P ickerill, 1990]. Sim ilarities o f this ichnotaxon to Phycodes w ere p ointed out by Beck (1916). A. strictusK si^zkiew icz displays sim ilar tendencies.

Thus, grouping in bundles can be regarded as the com m on feature o f Arthrophycus, w hich is included in th e diagnosis.

H ow ever, this feature does not occu r constantly, and there­

fore Arthrophycuscannot be included in PhycodesRichter.

Stratigraphic range: Low er C am brian (Linan, 1984) - L ow er M iocene (A lexandrescu & B rustur, 1984).

E m e n d e d d ia g n o sis: Sm all A rthrophycus, approxim ately circular in cross-section, w ith very fine, delicate perpen­

dicular ribs. Structures are distinctly arcuate in vertical plane and plunge into sole o f beds.

M aterial: 5 slabs (U JTF 124, 131 (holotype), 1318, 1508, 1523).

R e m a rk s: The holotype o f A rthrophycus strictus K si^zkie- w icz (U J T F 131, Fig. 4) contains tw o different trace fossils treated by K siazkiew icz (1977) as variations o f the sam e ichnospecies. H ow ever, these trace fossils display enough different features for th eir separation at the ichnospecies level. The first trace fossil is represented by short hypich- nial, perpendicularly striated, sim ple ridges, w hich dip into the bed at both ends (Fig. 5). T hey are elevated at the m iddle part and form w ide, variably oriented arches, w hich are 4 -6 m m in diam eter. Ridges o f the sam e m orphology are better and m ore com pletely preserv ed in other specim ens (e.g. UJ TF 124), w hich w ere determ ined by K siazkiew icz as A.

strictus. In som e more com plete specim ens, the ridges tend to form bunches, w hich plunge into the sole o f beds (Fig. 6).

com m only branched ridges, w hich do not form bunches and are not bent in arches (Fig. 5 B -C ). The ridges are covered w ith very fine p erpendicular striae and are distinctly thinner than the ridges o f the first type. T heir diam eter ranges from 0.4 to 1.2 m m . A bout h a lf o f th e ridges are branched, alw ays at a sharp angle. Ridges o f th e second type are alm ost iden­

tical to Sabularia tenuis K si^zkiew icz. T hese trace fossils differ only in the lack o f the p erpendicular striation in m ost specim ens o f S. tenuis. H ow ever, som e ridges o f the latter ichnotaxon, including the holotype (U J TF 1686), display faint perpendicular striation, w hich w as noted also by K si^zkiew icz (1977, p. 71). P reservation o f th e fine striation depends strongly on cohesion o f substrate and w eathering.

Thus, degree o f p reservation o f the striation is not a suffi­

cient criterion for the ichnotaxonom ic separation o f these trace fossils and therefore S', tenuis is included in A rthrophy­

cus. The ichnospecies nam e o f S. tenuis is retained, as A.

tenuis, for th e second type o f ridges. For the first type o f ridges the nam e A. strictus is retained.

The specim en U J TF 1318 indicated by K si^zkiew icz (1977, text-fig. 10b) as B uthotrephis spec, indet. displays distinct features o f A. strictus.

A. strictus w as regarded by K si^zkiew icz as repre­

senting a feeding burrow o f polychaetes. It occurs in the Al- bia n -S en o n ian flysch deposits o f the C arpathians (K si^zkiew icz, 1977). A n o t w ell preserved occurrence, treated therefore reservedly, is n oted in the Eocene flysch o f R om ania (A lexandrescu & B rustur, 1982). B rustur & Stoica (1993) reported A. cf. strictus from U pper Eocene flysch.

Paczesna (1996) d escribed A. strictus from the shallow - w ater C am brian deposits, b u t it displays a m edian furrow transecting the p erpendicular ribs. T herefore, it is excluded from this ichnospecies.

lindrical probes.

R e m a rk s : H alopoa w as described, but not illustrated by T orell (1870). A ndrew s (1955) designated H. im bricata Torell as the type ichnospecies o f this ichnogenus. M artins- son (1965) synonym yzed H alopoa com posita Torell (1870),

Scotolithus m irabilis Linnarson (1871) and H alopa im bri­

cata, and illustrated the lectotype o f the latter ichnotaxon.

He tried to com pare H. im bricata to G yrochorte H eer. H ow ­ ever, Jensen (1997) show ed that H. com posita and S. miri- abilis are different ichnospecies and that the com parison to G yrochorte cannot be accepted. H akes (1976) tu rn ed his at­

tention to the strong sim ilarities betw een H alopoa Torell and Fucusopsis Palibin in V assoevich (1932). A ccording to the description by Jensen (1977), H alopoa displays the sam e significant features as F ucusopsis. H ow ever, Jensen included this tw o ichnogenera in P alaeophycus. A lso P em ­ berton & Frey (1982) included F ucusopsis in P ala eo p h ycu s, w ho related P alaeophycus to passively fdled, open, w alled burrow s, including specim ens th a t display longitudinal striation. H ow ever, the origin o f the longitudinal striation m ay be diverse and related to diverse tracem aker behaviour or taphonom ic processes. The longitudinal striation m ay be produced actively by locom otory organs and/or passively by body appendages o f tracem aker. Its preservation strongly depends on cohesion o f the substrate. O ther types o f longi­

tudinal striation m ay be produced by m icrofaulting con­

nected w ith collapse o f burrow s or w ith com pressional faulting due to tension caused by tracem aker from interior o f burrow . This type o f striation is a p ro d u ct o f a unique behav­

iour, w hich can be interpretet as diagnostic feature at the ichnogeneric level. The latter idea w as proposed for F u ­ cusopsis (O sgood, 1970, p. 380; Seilacher, 1990b). In the case o f the K si^zkiew icz m aterial, there is no wall and no evidence that the burrow s w ere open, and therefore it does not conform w ith the idea o f P alaeophycus sensu P em ber­

ton & Frey (1982). Trace fossils o f this type, especially H.

im bricata (=F. angulata) from the Ksic(zkiewicz m aterial are com m only densely crow ded and they rew ork the low er­

m ost p art o f turbiditic beds. T hey are rather produced by de­

posit feeding organism s. T heir outline is not sharp and di­

am eter is not constant.

The cross-sections o f the H alopoa specim ens display several overlapping probes, w hich are com m only stacked in vertical plane (Fig. 8 B -C ). The trace fossils form a Teichi- chnus-like structure, how ever m uch less vertically and regu­

larly developed than in Teichichnus Seilacher. Som e probes o f H alopoa diverge aw ay from som e objects, for instance other fills o f burrow s o f the sam e ichnotaxon, and jo in once again behind the object (Fig. 9B). F orm ation o f each new com ponent probe is connected w ith pushing out o f the for­

m erly rew orked sedim ent in the older probe w hich results in the form ation o f an irregular longitudinal striation. D efor­

m ation o f the lam inae above the trace fossls (Fig. 8) indi­

cates that the sedim ent w as pushed out o f the burrow inte­

rior. The burrow s w ere presum ably form ed by intruding in the sedim ent by the tracem aker.

Teichichnus is never so long, lacks external sculpture, and is m uch m ore extended in the vertical plane. Therefore, H alopoa and Teichichnus should rem ain separate. O ne can conclude th at H alopoa represents sufficently unique behav­

iour for its retention as ichnogenus.

K si^zkiew icz (1977) regarded th e striation o f F ucusop­

sis (= H alopoa) as resulting from the sculpture o f the trace­

m aker, w hich probably belonged to priapulid w orm s. Such explanation does not conform w ith the trace fossil m orphol­

(11)

ganic-rich lam inae can be observed. H alopoa exploits rarely occupy tiers in the sandstone part o f turbiditic beds.

R e m a rk s : The discussed ichnotaxon, described by Ksi%z- kiew icz as Fucusopsis a n n u la ta , is included in H alopoa Torell in this paper. F. annu la ta w as reservedly included in Palaeophycus: alternus Pem berton & Frey (1982). In the

sam e year, D ’A lessandro included F. annulata K si^zkie- w icz (1970, non 1977) in R adionereites G regory. F ucusop­

sis annulata described by K si^zkiew icz in 1970 w ithout designation o f the holotype, com prises tw o different trace fossils. In 1977, K siazkicw icz designated the holotype, w hich corresponds only to the specim en illustrated in 1970 in fig. Ir2. The specim en illustrated in fig. l r l is related to Im ponoglyphus V ialov in this paper. Irrespective o f these facts, D ’A lessandro (1982) included both these speciem ns o f F. annulata K siazkicw icz 1970 non 1977 in R adionere­

ites G regory. H ow ever, D ’A lessandro e t al. (1987) then ex­

cluded the m aterial o f D ’A lessandro (1982) from R adione­

reites and erected for it a new ichnogenus, R utichnus, w hich lum ps certain m eniscate trace fossils. They reservedly in­

cluded F. annulata Ksiq.zkiewicz (1977, non 1970) in R u ­ tichnus and suggested the presence o f a m eniscate internal structure in the K siazkiew icz specim ens.

The K siazkiew icz m aterial, including the holotype, does not display any evidences o f internal m eniscate struc­

ture, including in specim ens sectioned along the trace fos­

sils. It displays, how ever, features o f H alopoa (see the dis­

cussion o f this ichnogenus). The m orphology o f H. annulata is due to a special behaviour o f tracem aker. A part from re­

quely in sedim ent, retreated, and rep eated its action along wide, shallow , vertical or oblique, and asym m etrical U- shaped sub-courses. This resulted in the occurrence o f p er­

der Hormosiroidea S chaffer at the ichnogeneric level is rather the problem o f tradition and m inor m orphological features than use o f significant diagnostic features.

S eilacher (1977a) regarded the spherical “cham bers” o f Hormosiroidea as sectioned vertical burrow s th at protrude from the horizontal burrow tow ard the bottom . H e included Saerichnites Billings and Rhabdoglyphus V assoevich in Hormosiroidea Schaffer. This ichnotaxon w as tentatively included in the graphoglyptids (Seilacher, 1977a). Such a concept o f Hormosiroidea cannot be accepted.

T he type ichnospecies o f Hormosiroidea, //. florentina S chaffer (1928), consists o f a row o f sm all bulbs connected by a string (Schaffer, 1928; H antzschel, 1975, p. W 70, fig.

40.3) (Fig. 11B). This ichnotaxon w as ten tatively included in the graphoglyptids (Seilacher, 1977a). Saerichnites con­

sists o f one or tw o parallel row s o f casts o f vertical shafts (U chm an, 1995). R elation o f Saerichnites to H. florentina is problem atic. P robably, the bulbs o f H. florentina, w hich are m uch greater than the string diam eter and w hich tend to be a little lobate in outline, do not represent vertical burrow s, but m ore likely breeding (?) structures. Thus, single or double row s o f vertical o r subvertical burrow s or single or double row s o f casts o f their outlets represent a separate ichnogenus Saerichnites B illings (U chm an, 1995).

Hormosiroidea S chaffer is proposed as the p ro p e r nam e for the discussed trace fossils. O lder nam es (see the list o f ichnotaxa included in Hormosiroidea) are either applied for trace fossils recently described under o ther ichnogenera or can be treated as forgotten (nom en oblitum ) (see S tanley &

P ickerill (1993).

S tanley & Pickerill (1993) discussed the taxonom y o f Rhabdoglyphus V assoevich (=Protovirgularia M cC oy in this paper) and Fustiglyphus V ialov. T hey kep t these ichno­

tax a separate, as w ell as Hormosiroidea Schaffer. N ev e rth e­

less, sim ilarities betw een Fustiglyphus and Hormosiroidea are clearly distinct (Fig. 11), as n oticed by O sgood (1970) and H antzschel (1975), and th ese ich n o tax a are com parable at the ichnogeneric level an d the d ifferences betw een them can be regarded as these at the ichnospecies level. T here­

fore, Fustiglyphus V ialov is a ju n io r objective synonym o f Hormosiroidea Schaffer. The cham bers o f Fustiglyphus w ere interpreted also as possible bro o d structures, sim ilarly to interpretation o f Hormosiroidea florentina Schaffer (U chm an, 1995).

C ham berlain (1977) included w ith hesitation, expressed by “ cf.” , a few taxa in Hormosiroidea. T hese are: Halimeda saporta Fuchs (1894a), Hormosira moniliformis H eer (1877), and Arthrodendron difussum (U lrich, 1904). H ow ­ ever, these form s represent body fossils o f large foram ini- fers and cannot be included in Hormosiroidea.

All these trace fossils are included in H orm osiroidea annu- lata (V ialov) in this paper.

The specim en U J TF 994 (Fig. 13) probably belongs to H. annulata.

Stanley & P ickerill (1993) regarded the cham bers o f H.

annulata as brood structures, w hich is probable. It is diffi­

cult to explain the m orphology o f this trace fossil as a de­

posit feeding structure as w as previously suggested (B oucek

& Elias, 1962; C ham berlain, 1977). The thin strings that com e out from cham bers (e.g. S tanley & Pickerill, 1993) and cross bedding, i.e. in the direction o f the sea-floor, can be produced by ju v e n ile tracem akers leaving the cham bers or by predators (Fig. 11).
