“…A more recent discovery of a Cenozoic reef fish fauna stems from the lower Oligocene of Italy (Marramà et al, 2022). Otoliths of fossil reef fishes are even more rarely recorded and usually only as minor faunal components (e.g., Carolin et al, 2022). Here, we describe a rich otolith association from back-reef environments of the middle Miocene (late Badenian) barrier reef underlying the Medobory Hills in western Ukraine (Medobory Reef or Medobory barrier reef in the following).…”

The Medobory Hills barrier reef in western Ukraine represents a unique environment during the late Badenian that existed for a relatively brief time. Here, we describe 170 specimens of otoliths and scarce skeletal elements that were collected in the back-reef environment of the central part of the barrier reef in the city of Horodok. They represent a rare window into a reef-associated bony fish fauna. The otolith assemblage is very diverse and differs in several aspects from time-equivalent otolith associations described from other regions and environments within the former Paratethys. The Medobory back-reef otolith assemblage is dominated by a highly diverse gobioid community, several of which are believed to reflect specific reef adaptations that have not been identified elsewhere. A total of 26 species have been identified, of which eight are described as new, including two new genera. In the order in which they are described, the new taxa are as follows: Gobiidae: Gobius bratishkoi n. sp., Gobius ukrainicus n. sp., Parenypnias n. gen. inauditus n. sp., Parenypnias n. gen. kiselevi n. sp., Medoborichthys n. gen. podolicus n. sp., and Medoborichthys n. gen. renesulcis n. sp.; Blenniidae: Blennius vernyhorovae n. sp.; and Labridae: Coris medoboryensis n. sp. The environmental implications of the otolith-based fish fauna are discussed, and a supraregional correlation of late Badenian otolith associations throughout the Paratethys is presented.

“…Many of its species are found in the tropical to subtropical waters of the Indo-Pacific (Thacker & Roje 2011;Agorreta et al 2013). The genus has been known in the fossil record since late Burdigalian (from India; Carolin et al 2022) and from the Paratethys since the Langhian (early Badenian) (Schwarzhans et al 2020b).…”

“…Limited coeval data from the Eastern Paratethys are consistent with the rich fauna known from the Central Paratethys. Carolin et al (2022) studied otoliths from southern India, which stem from slightly earlier strata dating from the late Burdigalian, and indicate a relatively limited faunal influence from the Indian Ocean in the Paratethys (e.g., the Asterropteryx lineage of the Gobiidae). According to Sun et al (2021), the Tethyan Seaway had become a restricted marine environment in the area of the closure (central Iran and southeastern Turkey) during the time, which likely limited the faunal exchange.…”

Reconstructing fossil bony fish faunas using otoliths is a well-established method that allows a diverse and dense record in time and space to be assembled. Here we report about a rich otolith-based fish fauna from the middle Sarmatian s.l. (middle Bessarabian) from Jurkine, Kerch Peninsula, Crimea. The study is based on more than 5,000 specimens constituting 36 different species, 24 of which are new and 2 remain in open nomenclature. This assemblage represents the first major otolith association described from the Bessarabian. It also represents a fish fauna from the last continuous restricted marine environment that evolved in the Eastern Paratethys, was recruited from the Badenian/Tarkhanian fauna, and was not affected by the subsequent Khersonian crisis. The association of otoliths is characterized by a high content of endemic fishes that derived from the relatively well-known early Sarmatian s.l. (Volhynian) fish fauna, and it contains certain faunal elements that were trapped in the then-secluded Eastern Paratethys and did not range into younger strata. This forced endemic evolution explains the unusually high percentage of new taxa. The fish fauna is dominated by stenohaline marine shelf fishes apparently recruited from the Konkian and earlier Sarmatian s.l. (Volhynian) fauna after the Karaganian crisis. The families Gobiidae and Gadidae benefited most in this restricted marine environment, while deep-water fishes disappeared with the Karaganian crisis. In this study, we discuss the further evolution of Eastern Paratethyan fishes as far as can be reconstructed from the relatively limited data from post-Bessarabian strata, and we also outline targets for future research in the field. The stratigraphic sequence of the Jurkine section is being revised based on a detailed suite of benthic foraminifera. Implications for the stratigraphy of the middle and upper Sarmatian s.l., their boundary, and the paleoenvironments of this part of the Kerch Peninsula are discussed.

The Kutch Basin of western India exposes one of the most complete, fossiliferous marine Cenozoic sedimentary sequences of India. Precise depositional ages of these sequences are of great importance in the reconstruction of palaeoclimatic and palaeobiogeographic histories of the basin. Due to the poorly constrained foraminiferal biostratigraphic ages, we conducted high‐resolution 87Sr/86Sr chronology of the various fossiliferous, stratigraphically continuous units of Oligocene–Miocene strata in Kutch Basin. Besides updating the previously determined 87Sr/86Sr chronology, we report new numerical depositional ages for Oligocene–Miocene formations and members, and correlated these ages to the existing biostratigraphic schemes. The new 87Sr/86Sr data indicates a depositional age range between 28.64 + 0.29/‐1.11 and 23.51 + 1.53/‐1.85 Ma (Rupelian‐Chattian) for the Maniyara Fort Formation, between 23.07 + 0.94/1.39 and 18.09 + 0.24/‐0.57 Ma (Chattian‐Burdigalian) for the Khari Nadi Formation, and between 15.11 + 0.56/‐2.87 and 12.29 + 1.22/‐1.9 Ma (Langhian‐Serravallian) for the Chhasra Formation. The sedimentation rate, determined through numerical ages derived from 87Sr/86Sr, indicates an increase in sedimentation for the Khari Nadi (0.23 ± 0.04 cm/kyr) and Chhasra (0.12 ± 0.04 cm/kyr) formations, likely related to uplift of the Himalaya‐Tibetan plateau and intensification of the Indian Summer Monsoon. The bulk sediment element ratios (V/Ni, Ni/Co and V/Cr) indicate oxic to suboxic palaeo‐redox conditions during deposition of the Oligocene–Miocene successions of the basin. Based on new and updated 87Sr/86Sr chronology, the depositional environments and sedimentation rates of the Kutch sequence are correlated with changes in sea‐level, sedimentation rates in the Arabian Sea and Bay of Bengal, and the global climate changes across the Oligocene–Miocene boundary.
