Because of its suture line and juvenile shell morphology, Ammonites flexisulcatus belongs to the family Desmoceratidae, and is herein assigned to the upper Aptian genus Caseyella Cantú-Chapa. Our palaeobiological study documents a morpho-dimensional dimorphism based on small-sized, robust, ribbed microconchs with a short ventral rostrum, and large, high-whorled macroconchs with a simple aperture. This species occurs in the upper part of the Epicheloniceras martini standard ammonite zone in both the South Provence and Vocontian Basin of southeastern France. Another morphotype of Caseyella, which occurs in the lower part of the Epicheloniceras martini Zone of southern France and Spain, differs by a flattened ventral region in the juveniles; pending examination, they could belong to a new species or consist of an ecological variant of Caseyella flexisulcata.

A biometric analysis of the species Dorothia hauteriviana is proposed in order to identify its morphotypes and their biostratigraphic significance. This study aims to identify benthic foraminiferal assemblages and to propose an integrated biostratigraphy along the Valanginian to Hauterivian sequence of the Vergol and La Charce sections (Vocontian Basin). Two foraminiferal assemblages have been recognized. The Lenticulina nodosa foraminiferal assemblage ranges from the lower Valanginian to the basis of the upper Valanginian Saynoceras verrucosum ammonite standard zones (StZ). The Lenticulina busnardoi foraminiferal assemblage is recorded from the second half of S. verrucosum to the top of Neocomites peregrinus StZ.

Here, we document the oldest known representative of the extant genus Primeuchroeus Linsenmaier, 1968 based on a specimen from Priabonian (upper Eocene) Baltic amber, and described as Primeuchroeus groehni sp. nov. This finding is the oldest Chrysididae fossil indisputably attributed to an extant genus and refutes the hypothesis that modern genera are not older than Neogene in age, as hitherto believed. Additionally, we propose the reallocation of a recently described fossil genus and fossil species. The genus Sphaerocleptes Cockx et al. (2016), described in the subfamily Cleptinae from Cenomanian French amber, is transferred to Chrysidinae, tribe Elampini; this is the first temporal occurrence for the tribe, previously not known earlier than the upper Eocene. The fossil species Hedychridium rosai Brazidec and Perrichot, 2023 is transferred from the subfamily Chrysidinae to Amiseginae and we propose the new combination Atoposega rosai (Brazidec and Perrichot, 2023) comb. nov. These findings provide deep insights into the evolution of Chrysididae: within the Chrysidinae subfamily, established by the mid-Cretaceous, some of the modern generic lineages had already diverged by the upper Eocene, and the Miocene Chrysididae fauna was likely similar to the extant fauna, pending further discoveries. Based on our observations, the fossil record of Chrysididae shows more similarities to that of other diverse hymenopteran families than was previously thought.</div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141156331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specimens collected include four individuals of O. edulis and three individuals of M. gryphoides from the Sağlam village area, and one individual of H. hyotis from the Sarıca village area in Eğil. These specimens were found in the yellow-limestone facies and beige-white marl facies, which represent the thickest and largest sections of the Fırat Formation. For the Sağlam village area, O. edulis suggests a littoral environment with excessive detrital inputs, ranging from medium to shallow depths, and a warm subtropical climate. The O. edulis display a slender, small, and comparatively regular morphology, suggesting a preference for stable habitats commonly found in coastal regions with minimal environmental variability. Similarly, the presence of the fossil species indicates littoral environments characterized by nearshore shallow depths, low-energy conditions, normal salinity, and warm subtropical climatic conditions for M. gryphoides. For the Sarıca village area, H. hyotis is linked to reef and peri-reef environments, along with shallow tropical-subtropical marine paleoenvironments at depths of up to 50m. Overall, this study presents novel information about the paleoecological distribution of Early Miocene oysters and their first records in the Eğil district.</div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141249721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
