1. INTRODUCTION In the Aydıncık area an autochtonous sequence of plat- form carbonate rocks was deposited, ranging in age from the Liassic to the Aptian. The sequence conform- ably overlies Upper Triassic basal conglomerates, inter- bedded with mudstones and sandstones (DEMI . R T AŞ- LI, 1984), and is unconformably overlain by Upper Campanian fore-reef carbonate breccia and limestone (TASLI & EREN, 1999). The biostratigraphy of Jurassic-Cretaceous carbon- ate sequences of the Central Taurides has been studied by the author since 1997. The present work on the Ay- dıncık profile forms part of the ongoing studies, such as TASLI (2000). The Late Jurassic section is particularly rich in benthic foraminifera belonging to the families Pfenderinidae (Kurnubiinae) and Valvulinidae. This Benthic Foraminifera of the Upper Jurassic Platform Carbonate Sequence in the Aydıncık (I . çel) Area, Central Taurides, S Turkey Kemal TASLI association corresponds to that of coeval facies of the Mediterranean realm (HENSON, 1948b; SARTONI & CRESCENTI, 1962; HOTTINGER, 1967; GU©I∆, 1969; NIKLER & SOKA», 1968; VELI∆, 1977; SEPTFONTAINE, 1980) and is linked with shallow- water, protected lagoon carbonates. Jurassic benthic foraminifera from the Taurus Mountains were reported from north of Isparta (GUTNIC & MOULLADE, 1967), north and northwest of Antalya (BASSOULLET & POISSON, 1975), east of Kayseri (ALTINER & SEPTFONTAINE, 1979) and Munzur Dağ (BASSOU- LLET & BERGOUGNAN, 1981). The aim of this paper is to describe some important species of benthic foraminifera. For the present study, approximately eighty random thin-sections from twen- ty-five fossiliferous samples within the measured strati- graphic section were studied. Micropalaeontological determinations are based on the study of these random thin-sections and a large number of successive acetate peels and polished samples. 2. LOCATION AND FIELD DESCRIPTION OF THE AYDINCIK PROFILE The Aydıncık Upper Jurassic profile is located about 2 km along the road to Karaseki village west of Aydıncık (I . çel) town (Fig. 1). It continuously overlies an alterna- tion of dolomite and limestone of late Dogger age (TASLI, 2000) and is about 50 m thick. Its upper limit is marked by the reappearance of entirely dolomitic beds representing the transition between the Jurassic and the Cretaceous, which is easily recognizable in the field because of its morphological difference. The analyzed section consists of light brown, pre- dominantly thick-bedded limestones. C l a d o c o r o p s i s m i r a b i l i s FELIX, although occuring sporadically in the underlying beds (i.e. in the Upper Dogger), is so fre- quent and abundant that it seems to be lithologically dependent. 3.

Mersin Üniversitesi Jeoloji Mühendisliǧi Bölümü, TR-33342 I . ç e l , Türkiye. e-mail: ktasli@mersin.edu.tr Abstract The Upper Jurassic sequence of the Aydıncık (I . çel) area consists of platform limestones which were deposited in a subtidal, restricted lagoon environment. Stratigraphic distribution of benthic foraminifera and calcareous algae, examined in thin-sections, is shown in a range- chart. The microfossil assemblage indicates the Salpingoporella sellii subzone of the Kurnubia palastiniensis cenozone, corresponding approximately to the lower part of the Malm. Some benthic foraminifera with considerable stratigraphic value within the Meso- zoic Tethys are described. Among the benthic foraminifera, taxa of the family Pfenderinidae, especially the subfamily Kurnubiinae, are dominant and frequent throughout the sequence. The planispirally coiled taxa are represented by the families Nautiloculinidae, Charenti- idae and Cyclamminidae (subfamily Bucciccrenatinae). 2 Geologia Croatica 54/1 limestones continuously overlie limestones and dolomi- tes corresponding the underlying biostratigraphic unit, Paleopfenderina salernitana cenozone of SARTONI & CRESCENTI (1962) (TASLI, 2000). Kurnubia palas - t i n i e n s i s HENSON, an index species of the cenozone established by SARTONI & CRESCENTI (1962) in the Apennines, is frequent and locally abundant throughout the sequence. This species is known to occur through the whole Malm of the Mediterranean realm (e.g. VELI∆, 1977; SEPTFONTAINE, 1980). The presence of Salpingoporella sellii (CRESCENTI) (Pl. III, Fig. 10), a dasycladacean alga used as an index species in the Apennines (SARTONI & CRESCENTI (1962) and Dinarides (NIKLER & SOKA», 1968; GU©I∆ et al., 1971; VELI∆, 1977), indicates the S. sellii s u b z o n e which corresponds approximately to the lower part of the Malm. 4. MICROFACIES DEVELOPMENT AND PALAEOENVIRONMENTAL SETTING The limestones consist mainly of fossiliferous wacke- stones and biopeloidal grainstones, with oncoids. Intra- clastic grainstones with F a v r e i n a sp. only occur in the uppermost part of the sequence. The presence of abun- dant, well preserved Cladocoropsis mirabilis F E L I X , centimetre-sized oncoids and benthic foraminifera are characteristic for these limestones. Benthic foraminifera are most abundant regarding both the number of species and individuals, whereas calcareous algae are subordi- nate. Dasycladacean algae are represented by Salpingo - porella annulata CAROZZI (Pl. III, Fig. 11), which is locally common, and rarely by Salpingoporella sellii (CRESCENTI). Thaumatoporella parvovesiculifera (RAINERI) (Pl. III, Fig. 12) is frequent, but not abun- Fig. 1 The geographic subdivisions of the Taurides (after ÖZGÜL, 1984) and location of the Upper Jurassic section. dant. Bioclastic fraction is mainly composed of frag- ments of C l a d o c o r o p s i s , pelecypods and subordinately brachiopods (punctate), ostracods and echinoids. Cal- careous sponge spicules are locally abundant. Siliciclas- tic material is totally absent. Predominantly dense micrites and abundant oncoids indicate low energy in a sheltered environment and shallow-water conditions. Intraclastic grainstones with Favreina sp. in the uppermost part of the sequence indi- cate high energy conditions, resulting in the develop- ment of a regressive facies. 5.

IX, fig. 7. Material : Fifteen random thin-sections and ten suc- cesive acetate peels with approximately ninety speci- mens. D e s c r i p t i o n : Test is free, lenticular shaped, thick- ened towards the poles, with small axial depressions. Peripheral margin is rounded to subrounded. Septal sutures, observed in equatorial sections (Pl. I, Figs. 6, 7), are slightly depressed. Coiling is planispiral, occa- sionally streptospiral, and involute, with a tendency to become uncoiled in the later stage (Pl. I, Fig. 12). There are two or at maximum three and a half whorls. The number of chambers in the last whorl is nine to twelve. Chamber interiors are simple. Septa are curved and inclined in the direction of coiling, in continuity with the outer wall. The base of the septum against the previ- ous whorl is thickened and chomata-like (Pl. I, Figs. 8- 10). Septal spacing (= height of chamber) and height of the whorls slightly increase during the ontogeny. Mega- losphere is simple, spherical or slightly ovoid. Aperture is simple and central (Pl. I, Figs. 6, 7). Wall is calcare- ous microgranular (= finely agglutinated) with a kerio- thecal structure, occasionally visible only in the last whorl of large specimens (Pl. 1, Fig. 11). D i m e n s i o n s : Dimensions (in mm) are shown in Table 1. R e m a r k s : Because of its streptospiral coiling, sin- gle areal aperture, and the presence of chomata-like thickening at the base of the septa (Pl. I, Fig. 5), this form is herein assigned to the genus K a r a i s e l l a K U R- BATOV, 1971 (in LOEBLICH & TAPPAN, 1988). K a r a i s e l l a aff. u z b e k i s t a n i c a is a close homeomorph of the Cretaceous genus C h a r e n t i a NEUMANN, 1965, except its streptospiral coiling. The genus K a r a i s e l l a was placed in the family Charentidae by LOEBLICH & TAPPAN (1988) although they note that it did not show a canaliculate wall structure (keriothecal structure of HOTTINGER, 1967). Specimens in the Aydıncık mate- rial do not show a sharp change in the plane of coiling from early to later whorls and subacute periphery as in the type species. This form is similar to the genera B u l b o b a c u l i t e s MAYNC, 1952 and H a p l o p h r a g m i u m REUSS, 1860 in areal aperture and the streptospiral nature of coiling. However, the wall is distinctly agglutinated and simple in the former genus, and alveolar in the latter.

Karaisella aff. uzbekistanica differs from anoth- er Upper Jurassic species, Mesoendothyra izjumiana DAIN, 1958 (with its wall consisting of large pores, DAIN in BYKOVA et al., 1958), by the central posi- tion of the aperture, the presence of chomata-like thick- enings in the base of the septum and by a lacking of distinct streptospiral coiling. K a r a i s e l l a aff. uzbekistanica closely resembles the genus B o s n i e l l a GU©I∆, 1977 by its keriothecal wall structure and growth pattern, but differs from it in the absence of a peneropline stage with cribrate aperture and in having only a central aperture. In the latter, the aperture is at first basal, then central and finally cribrate as in “Mesoendothyra” croatica GU©I∆ (GU©I∆, 1969; FURRER & SEPTFONTAINE, 1977). The genus B o s - n i e l l a is represented by two species: B. oenensis f r o m the Lower Jurassic of NW Bosnia (GU©I∆, 1977) and B. fontainei from the Middle Jurassic of Thaïland (BASSOULLET, 1994). It is considered as a junior synonym of M e s o e n d o t h y r a DAIN (SEPTFONTAINE, 1988). Alternatively, BASSOULLET (1994) removed “M e s o e n d o t h y r a” c r o a t i c a GU©I∆ from the genus M e s o e n d o t h y r a DAIN, because of its keriothecal wall structure, and assigned it to the genus B o s n i e l l a G U- ©I∆, 1977. O c c u r e n c e : It is abundant in biopeloidal grainsto- nes with oncoids, in association with Nautiloculina cir - c u l a r i s and Kurnubia ex. gr. p a l a s t i n i e n s i s , whereas it is missing or rare in fossiliferous wackestones. Family Pfenderinidae SMOUT & SUGDEN, 1962 Subfamily Kurnubiinae REDMOND, 1964 Genus Kurnubia HENSON, 1948 Type species: Kurnubia palastiniensis HENSON, 1948 After SMOUT & SUGDEN (1962), who assigned HENSON’s (1948b) species Valvulinella jurassica a n d V. wellingsi to the genus K u r n u b i a HENSON and after SARTONI & CRESCENTI (1962), who considered the species K. jurassica synonymous with Kurnubia palas - t i n i e n s i s, REDMOND (1964) described, from isolated specimens only, three new species of K u r n u b i a : K . v a r i a b i l i s , K. bramkampi and K. m o r r i s i . MAYNC (1965) included all these species in Kurnubia gr. palas - t i n i e n s i s HENSON, except K. morrisi, considering the existence of intermediate forms. GU©I∆ (1969) adopted MAYNC’s (1965) opinion and considered the three infrasubspecific taxa as “forms” j u r a s s i c a , p a l a s t i n i e n - s i s and w e l l i n g s i. HOTTINGER (1967) redescribed K . p a l a s t i n i e n s i s in detail, including K. jurassica , and retained the three REDMOND’s (1964) species of Kur - nubia. Later, this common Late Jurassic genus has been recorded mostly under the name Kurnubia palastinien - s i s HENSON in many studies (e.g. BASSOULLET & POISSON, 1975; AZÉMA et al., 1977; VELI∆, 1977; FOURCADE et al., 1985; LUPERTO-SINNI & MAS- SE, 1994). In general, REDMOND’s (1964) species seem not to be accepted, probably owing to difficulties in comparing with isolated specimens. The aim of the following descriptions is to con- tribute more data to the existing knowledge on the sub- family Kurnubiinae, avoiding the creation of new taxa. Kurnubia ex. gr. palastiniensis HENSON, 1948b (Pl. II, Figs. 1-7) D e s c r i p t i o n : See description in HOTTINGER (1967). R e m a r k s : Our specimens display wide morpholog- ic variations and considerable differences in size. They vary from those smaller in size, only trochospirally, having a weakly developed central column and possess- ing a hypodermic network (SEPTFONTAINE, 1988) with first order partitions (Pl. II, Figs. 1, 2, 5), to those having a larger test with a marked central column, a more or less developed uniserial stage, and possessing a complete hypodermic network (Pl. II, Figs. 4, 6). The former have a simple, ovoid proloculus, measuring about 0.04 mm (inner diameter) and representing the megalospheric generation. They are included in this group due to the presence of the transitional forms. In the latter forms, the proloculus is not visible. The cen- tral column seems to be weakly developed in highly conical specimens (Pl. II, Fig. 6), whereas it is well developed in specimens having a relatively larger basal diameter (Pl. II, Figs. 3, 4). Kurnubia cf. morrisi REDMOND, 1964 (Pl. II, Figs. 8-12, 14) ?1964 Kurnubia morrisi new species.- REDMOND, p. 253, pl. 1, fig. 4. 1967 Kurnubia cf. m o r r i s i REDMOND.- HOTTIN- GER, p. 93, pl. 19, figs. 35-37. D e s c r i p t i o n : Test is fusiform, trochospirally coiled throughout the ontogeny. Early chambers are not visi- ble. Spiral sutures are depressed, at about 30°to the axis of coiling. Septal sutures are obscure. The wall is cal- careous, microgranular without agglutinated grains, possessing a complete hypodermic network. The prima- ry aperture is set in the inner margin of the peripheral zone where the septa do not meet the central column (Pl. 2, Fig. 11). It probably represents “intercameral foramina” (SMOUT & SUGDEN, 1962). Prolongations of the adjacent first order vertical partitions projecting inward from the epidermis adjoin to each other and coa- lesce with the interseptal pillars (Pl. II, Fig. 10). The second order vertical partitions are restricted only to the marginal zone of the chambers. The central zone has a trochoidally laminated appearance (Pl. 2, Fig. 14) 6 Geologia Croatica 54/1 which recalls the apertural plates intergrown with pil- lars in the Pfenderinidae. The base of the test is strongly convex in the centre and very obliquely set to the axis of coiling. D i m e n s i o n s : Axial length varies from 2.1-2.5 mm, measured in nearly axial sections. Basal diameter is ≥ 0.8 mm and exceeds up to 1.0 mm. The ratio of length/diameter oscillates around 2.5:1. The width of the peripheral zone surrounding the central zone is nearly constant throughout the adult stage, measuring 0.20-0.22 mm. The central column increases progres- sively in diameter, up to 0.5 mm. Remarks : K. cf. morrisi has a larger test and central column, and a wider peripheral zone than all other described species of Kurnubia and a complete hypoder- mic network consisting of two generations of partitions in the adult stage. Furthermore, specimens of Kurnubia ex. gr. p a l a s t i n i e n s i s do not exceed 0.7 mm in basal diameter. Purely because of the trochospiral coiling, this form is not considered as K. w e l l i n g s i ( H E N S O N ) . Six to eight tiers of chamberlets per chamber, men- tioned by REDMOND (1964, p. 253), are not account- able in random thin sections. Genus Conicokurnubia SEPTFONTAINE, 1988 Type species Conicokurnubia orbitoliniformis SEPTFONTAINE, 1988 Conicokurnubia orbitoliniformis SEPTFONTAINE, 1988 (Pl. II, Figs. 13, 15, 16) Description : Test is sharply conical (Pl. II, fig. 13), where chambers do not increase in diameter as added, and broadly conical where chambers increase slowly in diameter. The base is slightly to strongly convex in the centre, with a narrow imperforate rim. The cone side is straight. Proloculus is not visible. The trochospiral arrangement of the early chambers is suggested by traces of the spiral suture. Later and remaining larger portion of the test consists of a co-axial series of ten to seventeen very low chambers which increase slightly in height as added. Septal sutures are distinct and depres- sed. Each chamber has a peripheral zone with a com- plete hypodermic network. Each septum is inwardly thickened and then adjoins with the adjacent septum, forming buttress-like interseptal pillars (Pl. II, Fig. 15). The first order vertical partitions form a “reticulate zone” (HENSON, 1948a) in the centre of the test as seen in transverse sections (Pl. II, Fig. 16). Apertural pores are not observable. The primary aperture consists of an opening near the margin of the central zone (Pl. II, Fig. 15). D i m e n s i o n s : The broadly conical specimens have a basal diameter of 1.25-1.50 mm and a height of 1.75- 1.85 mm, measured in nearly axial sections. The sharply conical specimens have a basal diameter of 0.50-0.70 mm and a height of 1.25-2.0 mm, measured in nearly axial sections. The height of the last chamber, for both forms, is ≤ 0.1 mm. The width of the peripher- al zone surrounding the central column is 0.10-0.12 mm. Remarks : Specimens of this species from Aydıncık are closely comparable with SEPTFONTAINE’s (1988) figures (pl. II, figs. 12, 13) from the Oxfordian (?) to Kimmeridgian of Western Taurus, Turkey. However, the available axial and transverse sections are insuffi- cient for a complete description of the species. Conicokurnubia orbitoliniformis occurs throughout the Aydıncık Upper Jurassic section, in association with K u r n u b i a ex gr. p a l a s t i n i e n s i s . In the random thin-sec- tions, specimens with a marked uniserial stage of the latter might be confused with sharply conical specimens of C. orbitoliniformis. The width of the peripheral zone seems to be narrower than in Kurnubia palastiniensis and Kurnubia aff. morrisi. 6. BIOSTRATIGRAPHIC REVIEW AND CONCLUSIONS The characteristics of the Upper Jurassic limestone sec- tion from the Aydıncık (I . çel) area are the presence of C l a d o c o r o p s i s , benthic foraminifera, calcareous algae and the dominance of mudstones which indicate a sub- tidal, protected lagoon environment. Stratigraphic distribution of the benthic foraminifera and calcareous algae is shown in a range-chart. Micro- fossil assemblage corresponds to the S a l p i n g o p o r e l l a s e l l i i subzone of Kurnubia palastiniensis c e n o z o n e , established by SARTONI & CRESCENTI (1962). Ten species of benthic foraminifera are identified and figured. Those of considerable stratigraphic value within the Mesozoic Tethys are described. 7. REFERENCES ALTINER, D. & SEPTFONTAINE, M.
