Middle Triassic (Muschelkalk) conodonts from the SW margin of the Holy Cross Mts

A~CT: Twenty twoO &pecies and 'Subspecies of the conodon<t6 halVe been reco- gcized in the 'Middle TriassJ.c (lMuschelkalk) of .the SW tna:rg~n of ;the Holy Cross Mts. Basing oOn the oonodOnltS, the UiPpell." Muschel'kaJ.k of the region ha-s been cor- related with the Cetra.t£tes !Beds 'OIf Germainy. :In the Lower MU'~helkalk oOf the region, the species Pa,ragondoleUa na.'V'icula (Huokriede) and IP. exce'lsa MO'Sher,.

'charac1leirliBtic (yf the Alpine pooviJnee, have been srtated.

During the stratigraphic investigations of the Rot and Muschelkalk of the SW margin of the Holy Cross Mts (Trammer 1970); the conodonts have appeared to be useful fqr local and regional correlation. The preliminary results, presented in this contribution, are. based on the conodont material obtained from 49 samples ·collected in the profiles at Polichno, Stare ^Ch~ciny and Wolica (Fig. 1).' A poor state of out·crops enabled to the sampling only in some ihtervals of the Rot-Muschelkalk sequence (d. Fig. 2).

The conodontshave been found in. ,32 samples coming from the Lower and Upper Muschel~alk(Fig. 2). One of the samples (No. 9) from the Pecten discites ~eds(lithost!atigraph~c schema according to Senko- wiczowa 1957, 1959) has yielded as ,many as 200 conodonts in a 400 g rock sample, the number' being the most extreme in the investig"ated profile. The othe~ positive sampl~s>, taken froriI the Wellenkalk, J:,uk~wa Beds, Lima stTiataBeds and Pecten" discites .Beds(d. Fig. 2), contain the conodonts "in range of 1 to '42 specimens., in a similar rock volume.

The full list of the conodont species or subspecies (including their number and samples) is as follows (cf. PIs 1 and 2):

An att~mpt, based on the recordedc~nod'onts;"'atcorrelating the Upper Muschelkalk of the Holy Cross Mts and ., of Germany, the latter being recently subdividedihto '7 conodont zones by Kozur (1968), is presented.

The Upper Muschelkalk of the Holy Cross Mts is incomplete. The youngest biostratigraphic unit, according to Senkowiczowa (1957, 1959), is most probably the Ceratites spinosus Zone, so the Muschelkalk in the Holy Cross Mts ends with deposits corresponding to the Middle Ceratites Beds of Germany (Fig. 3).

The part of the Upper Muschelkalk of Germany, corresponding to deposits occurring in the Holy Cross'Mfs, comprises' 4 conodont zones (Fig. 3). However, -in the Holy Cross Mts only the two lowest zones (cf.

Kozur 1968) may be stated, and the boundary between' the 1st and 2nd zone lies within the Pecten discites Beds (Fig. 3).

The 1st zone is documented with characteristic assemblage of conodonts (samples 6 and 7) which incllldes G01,I-dolella (GcmdoleZZa) mombergensis mombergensis Tatge, Chirodella ' dinodoides (Tatge), Parachirognathus? pandodentata (Budurov) and Roundya meissneri Tatge, and' it comprises the lower and middle parts of the Pecten discites

Beds. The uppermost part

of

^the Pecten· discites Beds belongs to the 2nd zone, documented with conodont assemblage (samples· 8 and 9) including Gondolella '(Gondolella) mombergensis mombergensis Tatge, G.. (G.) . mombergensis meciia ~ozur and G. (G.) mombergensis pra'Va Kozur. The 2n~ conodont zone of Germany co~prises the Lower Ceratites Beds and theCeratites compresstis Zone of the Middle Ceratites Beds (Kozur 1968), so the uppermost Pecten discitffs Beds of the Holy' Cross Mts, on·the basis of conodont fauna, might have been ,correlated with the Lower Ceratites Beds .and/or the Ceratites compressus Zone. However, the Pecten discites Beds· are overlied, according to Senkowiczowa (1957, 1959), by limestones of the Ceratites robustus ZOne, so the uppermost part of these beds in the Holy Cross Mts has to correspond to the Lower Ceratites Beds of Germany (Fig.

3). "

Upper links of the Muschelkalk (i.e. Middle Ceratites Beds) are not exposed in the area, and no conodonts were recorded in the sample from the Terebratula lumachelle (cf. Fig. 2) at the top of the Holy Cross Muschelkalk, and thus the younger conodont zones of Germany could not have been distinguished here. . '

Occurrence of the species Paragondolella navicula' (Huckriede) and ,P. excelsa Mosherin the Lower :MUschelkalk of the Holy Cross Mtsis of some interest, as~hese species haveilot 'been recorded in the Muschelkalk

·of Germany, while they are knowt;i'from the Upper Anisian throught the Lower NotiCian of tIie' Tethyan'province(Huckriede 1958, Mosher 1968)~

and from the Lower Muschelkalk of Lower Silesia (Zawidzka 1970).

All other forms recorded .,in th:e Lower Muschelkalk of the Holy Cross Mts and Lower Silesia ^(cf. Zawidzka 1970), are known both from Germany and Tethyan province, which fact seems to support the previous assumption (Samsonowicz 1929) that the Polish province was more closely related to the Tethyan regions than the German one.·

The subspecies Gondolella (Gondolella) mombergensis momber- gensis Tatge was recorded not only in the Upper, but also in the Lower

'. Correlation of ·the Upper fM'Ilschelkal:k of the Holy CrOBS Mts and Germany

Muschelkalk of the Holy Cross Mts and of Lower Silesia ^(cf. Zawidzka 1970). This form is, according to Kozur (1968), a guide fossil for the 1th and 2n'd zones of the Upper Muschelkalk; moreover, the conodont assemblage of the 1st zone of the Upper Muschelkalk in Germany differs from those from the Lower Muschelkalk in occurrence of this very subspecies ^(cf. Kozur 1968).

The subspecies Cornudina breviramulis minor Kozur, a guide fossil of the 2nd and 3rd zones of the German Upper Muschelkalk (Kozur 1968), was stated in the Holy Cross Mts only in the Lower Muschelkalk.

As a chara<:teristic form for the Lower Muschelkalk,' the species NeospatJtodus kockeli (Tatge) may be regarded, as it was recorded only in that substage,both in Germany (Tatge 1956, Wilczewski 1967) and in the area studied.·'

In one case, a widely accepted taxonomic concept was modified by including the spedes kockeli, established by Tatge (1956), to the genus Neospathodus Mosher, 1968, as appears from the structure of the base and of the basal"cavity. Previously this species was included by Tatge

MIDDLE TRIASSIC CONODONTS 385

(1956), Budurov (1960) and Wilczewski (1967) to the genus Ozarkodina Branson & Mehl, 1933.

The preliminary statement of an, abundantconodont fauna in the Upper Muschelkalk, and slightly scarcer in the Lower Muschelkalkof the Holy Cross Mts, shows furthur investigations to be necessary and may result in a more detailed biostratigraphic correlations with the classic profiles in Germany and in the Alps.
