This paper presents new insights into the systematic and evolution of Orthomyctera andina (Rovereto, 1914), one of the most abundant species within Caviidae Fischer de Waldheim, 1817, in the fossil record of this region. A comprehensive anatomical description and taxonomic review of Orthomyctera andina in a phylogenetic context is provided. Moreover, it includes a redescription of the type specimen of Orthomyctera rigens (Ameghino, 1888). The taxonomical results confirm that O. andina belongs to a different genus: Orocavia (Kraglievich, 1932). The phylogenetic analysis further confirms the placement of both species within Caviinae Fischer de Waldheim, 1817. Orthomyctera andina is the sister taxon of the clade that includes Microcavia Gervais & Ameghino, 1880, Dolicavia Ameghino, 1916, Neocavia Kraglievich, 1932, and Orthomyctera Ameghino, 1889. It is supported by a combination of plesiomorphic characters (e.g. furrow opposite to hypoflexus/id in molariforms) shared with basal taxa and Dolichotinae Pocock, 1922 and derived characters (such as a terreced palate, external auditory meatus below the occlusal surface , length of p4-m1 shorter than length of m2-m3) shared with Caviinae. This study aims to elucidate the taxonomic status of these poorly known rodents and their relationships within Caviidae. Additionally, it incorporates a biogeographic analysis of caviomorph communities from the late Neogene in Argentina.","PeriodicalId":51002,"journal":{"name":"Comptes Rendus Palevol","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141929263","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}

Here we study both the morphology and the microanatomy of the osteoderms in Paleosuchus palpebrosus (Cuvier, 1807), in order to both assess the distribution of bone ornamentation over the osteoderm shield, and to compare the porosity between the dorsal osteoderms with the non-dorsal osteoderms. Since both the ornamental pit excavation and the bone porosity are relevant proxies to the osteoderm blood vessel content, we mapped the distribution of the vascular network within the osteoderm shield in P. palpebrosus. Our results show that both the bone ornamentation and the bone porosity are significantly more pronounced within the dorsal shield osteoderms. Our results suggest that the dorsal osteoderms may be involved in heat transfer via the superficial blood vessels that are located in the ornamental pits if they are artificially exposed to a basking lamp in captive conditions; it is however unlikely to be the case under the canopy of the equatorial forest since the sun exposure is poor. We therefore hypothesize that the dwarf crocodylian extended osteoderm shield mostly consists of a labile calcium resource that would allow to buffer the diet variations which are related to the various equatorial forest niches (i.e., streams, excavated pools, jungle floors, caves).","PeriodicalId":51002,"journal":{"name":"Comptes Rendus Palevol","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140241770","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}

Representatives of the family are notoriously homeomorphic, which makes their taxonomy a major challenge of modern ostracodology. Their classification has thus been problematic since the 1970s. Here we present the first CT-scan investigation of recent and fossil ornate Bairdiidae valves in order to characterize and evaluate the taxonomic significance of unexploited characters, such as pores and pore canals. Thanks to 3D tomography, we explore the distribution of pores at the surface and the pathway of pore canals within the valve wall of the recent genus Triebelina van den Bold, 1946 and the Triassic genera Nodobairdia Kollmann, 1963 and Mirabairdia Kollmann, 1963. In Triebelina indopacifica van den Bold, 1946, we describe an unexpected system of double pore canals, so far unknown in ostracods. We confirm that pore systems in Triebelina have largely intramural positions. In the Triassic Bairdiidae (Nodobairdia mammilata Kollmann, 1963 and Mirabairdia pernodosa Kollmann, 1963), we recognize simple unrimmed and massively nodular pores as well as marginal pores. Lateral normal pores of the Triassic specimens appear to be mostly in intra-solum positions. Although still exploratory and at the limits of the tomographic resolution, these observations provide new evidence to reject the formerly proposed synonymy of Triassic genera with Triebelina, which obstructed the establishment of a phylogenetic classification.","PeriodicalId":51002,"journal":{"name":"Comptes Rendus Palevol","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140260180","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}

It is also an important step in any test of the researcher’s understanding of the anatomy of the fossil. Even so, there is no recognized method for its completion, leaving the actual process to the individual undertaking the investigation. While this is often accomplished in an appropriate manner, there remains extensive room for error. With the onset of cladistic methodology dating back to the 1980s, character state description has become ever more critical in establishing phylogenetic histories, and over a period of 40 years, character state interpretation has often relied on specimen drawings and reconstructions. Based on a career dedicated to the detailed skeletal reconstruction of tetrapods, the content presented here highlights a stepwise approach that is designed to minimize error and increase the value of fossil reconstructions. We describe the skull reconstruction of the Palaeozoic tetrapod Limnoscelis paludis Williston, 1911 and highlight some of the more critical strategies that are necessary to maximize accuracy and hence increase phylogenetic reliability as well as support opportunities for testing anatomical interpretations as well as functional and ultimately behavioural interpretations. We also take the opportunity to highlight the extensive career contributions made to the field of palaeontology by Diane Scott, who for over 40 years has represented the nec plus ultra of fossil preparation, illustration, and reconstruction.","PeriodicalId":51002,"journal":{"name":"Comptes Rendus Palevol","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139958940","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 fossils include a partial skull, several maxillary and mandible fragments and isolated teeth. They have been partially illustrated, but never described excepting the isolated teeth of Pogana. The previous assignments were confusing, ranging from Chilotherium schlosseri (Weber, 1905) and C. cf. sarmaticum for Reghiu specimens to an indeterminate species close to C. sarmaticum Korotkevich, 1958, C. kiliasi (Geraads & Koufos, 1990), and C. kowalevskii (Pavlow, 1913) for Pogana teeth. Based on descriptions and comparisons with other Chilotherium remains, all specimens from Romania can be referred to C. schlosseri. Chilotherium schlosseri is the most widespread species of the genus, ranging from Eastern Europe to Central Asia. The presence of this genus in Romania, and more globally in Eastern Europe, attests to a transition area between the more closed and wooded environments of Western Europe (where Chilotherium is absent) to the more open ones in Asia.","PeriodicalId":51002,"journal":{"name":"Comptes Rendus Palevol","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006443","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}
