(Tabl. I—XV i 1 fig.)
A b s t r a c t : This paper represents the second part of an article published in volume 39/1969 pp. 133—181 dealing with the Cenomanian foraminiferal fauna in the southern part of the Eastern Carpathians. A detailed microibiostratigraphy of these deposits has been established with use of planktonie foraminifera complemented by benthonic forms. A systematic presentation of the benthonic foraminiferal fauna follows a general discussion of the sequence of the planktonie foraminiferal zones which have been recognized.

position is also reflected by th e fo ram in iferal content, w h ere th e re m ay be observed an obvious m ix tu re of elem ents of tw o assem blages such as:

Thus, th e conclusion m ay be d ra w n th a t m icr op aleon t o logi cally th e se

T he L ow er C enom anian is rep resen ted by a fo ram in iferal assem blage c o n tain in g both, b en th o n ic an d plan k to n ie species in abundace. W ithin th e p lanktonie assem blage th e re is a strong developm ent of th e genus R ota
lipora, and th is continues progressively up to th e la te s t p a rt of th e Ceno

This g ro w th is so strong th a t w ith in th e M iddle, b u t p a r tic u la r ly w ith in th e U p p er C enom anian, th e b en th o n ic fa u n a of fo ram in ifera is alm ost en tirely concealed. W hen follow ing th e d evelopm ent of th e fo ram in iferal assem blage th ro u g h th e e n tire C enom anian stage, th e in terd ep en d en ce ex istin g b etw e e n th e d eg ree of d evelopm ent of th e b en th o n ic an d of th e plan k to n ie fo ram in ifera becomes v e ry obvious. T he in v erse relatio n of p ro p o rtio n ality of th ese tw o giroups of fo ram in ife ra is 'd e a rly dem o n strated . T he re m a rk able degree of developm ent of th e p lan k to n ie foram inifeira has enabled th e w rite r to subdivide th e C enom anian stage into a sequence of zones, subzones an d even zonules. T he ab u n d an ce of species an d specim ens in th e C enom anian fau n as in d icate th a t th e y do n o t correspond in an y w ay the assem blages of th e flvsch ty p e w hich C arp ath ian m icropaleontologist a re used to find. W ith m in o r exceptions, th ese assem blages occur also w ith th e sam e or g re a te r d eg ree of developm ent w ith in th e deposits of a n ep i

This opinion is also co n firm ed b y th e fact th a t in som e p a rts of this basin, w h ere th e ep ico n tin en tal in flu en ce is n o t in evidence in th e basal p a r t of th e series, th e fo ram in iferal fa u n a is com posed exclusively o r dom i

com es p ercep tib le — a lth o u g h th e p lan k to n ie fau n a does n o t m ak e u p th e basal p a rt as in th e o th e r sectors — it n ev erth eless causes an obvious change w h ic h is also discern ib le in th e b enthonic fauna. In th is sense, th e outcrop fro m D ealul S tin ii (Int. B uzaului) is significant.
Likew ise, in th e case of th e C enom anian deposits in th e so u th ern a re a
ary view p o in t is th e planiktoriic fauna. T he b en th o n ic fa u n a ex h ib its a m uch slow er evolution, in d iv id u al ran g es of some species cross one or m ore stage boundaries. B ecause of th e considerations, a detailed m icrobio

C onsidering th e problem from a m icro b io stratig rap h ic view point, the C enom anian deposits in th e so u th ern p a r t of th e E astern C arp ath ian s — although stru c tu ra lly belonging to d iffe re n t units, i.e .: th e C eah lau N appe and B obu U nit, th e Dimibovicioara Couiloir a n d th e C urbicortical F lyseh or T eleajen F lyseh — m a y be sep arated in to th e follow ing subdivisions:
H edbergella Z o n e . S tratig rap h ically , th is zone co rresponds to th e V ra- conian an d is ch aracterized, as h a s been show n, from a m icropaleontolo- gical view point, by th e m ix tu re of th e tw o fau n al types (U pper A lbian an d L ow er C enom anian). W ith in the populations of th is Z o n e , how ever, th e dom in an t elem ent is th e genus H edbergella w ith one or sev eral species (H. delrioensis (C a r s e y ) H. planispira (T a p p a n), H. trocoidea (G a n - d o 1 f i) w ith w hich are associated th e firs t occurrence of T rita xia gaultina gaultina ( M o r o z o v a ) . T his species continues its ev o lu tio n p a ra lle l to th e genus Rotalipora w ith a series of m orphotypes. T he rem ain in g m icro
fau n a in this zone, w hich is ra th e r poor, is composed of: R eophax m in u ta T a p p a n, R. deckeri T a p p a n, K alam opsis g rzyb o w skii ( D y l ^ z a n k a ) , Dorothia pupa ( R e u s s), D. oxycona ( R e u s s), T extu la ria foeda R e u s s , w hich in som e sam ples — P rah o v a V alley — becom e th e d om inant elem ent, G loborotalites brotzeni H o f ' k e r , Nodosarella (Clarella) bulbosa t en D a m , H eterolepa polyraphes (R e u s s), P raeglobotruncana delrioensis ( P l u m m er) (abundant), P. stephani stephani ( G a n d o l f i) (rare), R o ta lipora apenninica ( R e n z ) (rare).
C orresponding to th is ‘zone in th e outcrop of S tin ii H ill-Int.

T he fact th a t these deposits a re overlain b y a sequence of sedim ents in w hich th e planktonic form s fro m below reappear-H edbergeZfa planispira ( T a p p a n ) , Praeglobo- iruncana stephani step h a n i (G a n d o 1 f i), and th e n Rotalipora and Scha- ckoina — as w ell as th e presence of som e ag g lu tin ated form s w hich occur also in th e A ucellina beds, enables us to co rrelate th ese assem blages and assign th em to th e sam e age i.e., th e V raconian.
Rotalipora Z o n e . T his zone corresponds paleontologically to th e tim e w h en th e genus Rotalipora co n stitu ted a m ain com ponent of th e p lanktonic fo ram in iferal fauna. S tra tig ra p h ic a lly this zone corresponds alm ost exactly to th e in te rv a l assigned to th e C enom anian, and m ay be subdivided in to th e follow ing subzones:
■— T he Rotalipora apenninica S u b z o n e ;
— 6 -
— Th e Rotalipora brotzeni — R. globotruncanoides S u b z o n e ;
—■ The Rotalipora cushm ani — R, reicheli S u b z o n e .
W ith in th e first subzone, th e p lan k to n ie p opulation is dom inated by th e Rotalipora aperminica group w ith its various subspecies o r m orphological types, to w hich can be added Rotalipora ticinensis ( G a n d O' 1 f i) and R. techam aensis M a r i a n o s & Z i n g u 1 a. S tratig rap h ically , this sub- zone begins .somewhat below th e V raconian/L ow er C enom anian boundary, so th a t it also includes th e la te st p a r t of th e V raconian, an d co n tin u es into th e basal p a r t of th e M iddle C enom anian. If one follow s th e evolution of th e R otalipora apenniiniea group, at th e tim e w hen th e p lan k to n ie p o pula

W ithin th e la tte r zonule th e first rep resen tativ es of th e Rotalipora brotzeni an d R. globotruncanoides groups appear, but, of course, th ey are n o t common. In th e D ealul S tin ii outcrop, w here, as m en tio n ed before, the ep ico n tin en tal in flu en ces a re less pronounced, th e Rotalipora Z O' n e has a m uch sm aller ex ten t.

In its lo w er p art, corresponding to th e H edbergella S u b ' z o n e, we hav e sep arated th e P. alternans S u b z o n e in. w hich, as read y m en tio n ed above, th e arenaceous fo ram in ifera prevail, w h ile in its u p p er p a rt, corresponding to th e Rotalipora apenninica S u b z o n e , w e have sep arated th e H edbergella planispira S u b z o n e (this being th e first strongly developed p lan k to n ie species a fte r th e a re n a ceous phase). H ere also T rita xia gaultina (M r o z o v a ) occurs for th e first tim e still in th e low er subzone, corresponding to th e situ atio n in all o th e r sections. In th e com position of th e benthom ic fauna, th e H. planispira S u b z o n e is v e ry sim ilar a n d alm ost identical w ith the R. apenninica a p en n i
nica S u b z o n e, this being also th e decisive c rite rio n w hich p e rm itte d th e correlation.
T he Rotalipora brotzeni — R. globotruncanoides S u b z o n e follows above, b u t h ere th e p lan k to n ie population is dom inated b y tw o species. The boundaries b etw een these tw o subzones as w ell as b etw een th e o th e r ones, a re n o t of an absolute value. In establishing th em we have ta k e n into account th e w hole population, an d n o t m e re ly th e first occurrence of a species o r of a group of species.
As a connecting elem ent b etw een th e se tw o subzones, a n d to d em o n stra te th e above statem en t, th e Rotalipora apenninica evoluta Z o n u l e o c c u rs; it shows a n appreciable developm ent in th e u p p e r p a rt of th e Low er C enom anian, a n d in the low er p a rt of th e M iddle C enom anian. In th e D ealul S tin ii outcrop, th e genus Schacikoina w ith ¡its various C enom anian species a n d subspecies occurs w ith in th is subzone.
T he R otalipora cushm ani — R. reicheli S u b z o n e corresponds to the U p p er C enom aian b u t also em braces th e basal p a rt of th e L ow er T uranian.
