It corresponds to the first occurrence of a vertebrate in the Graissessac Basin. The specimen consists of a partial skull articulated with the pre-sacral part of the vertebral column, ribs, scapular remains and skin patches. Yet its poor preservation limits its identification to Temnospondyli indet., even if it presents a mosaic of characters found in both dvinosaurs (short preorbital region, small orbits, a broad cultriform process anteriorly widened) and dissorophoids (elongated skull table, proportionally long and slender ribs). The specimen is identified as a possible paedomorphic adult. This specimen highlight the close resemblance between dvinosaurians and micromelerpetid dissorophoids, especially at a larval stage. In France, Carboniferous temnospondyls were known so far in the basins of Blanzy-Montceau, Commentry and Decazeville. This new discovery therefore increases the range of this group in another basin (Graissessac) and it corresponds to one of the rare Carboniferous temnospondyl found south of the Variscan Belt. It also confirms the strong dispersal of the group during the Carboniferous and the closed interconnections between the lacustrine European basins. Finally, the fact that this new fossil has been discovered by a volunteer strenghtens the role of non-institutional palaeontologists in the search of specimens important for science.</div></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":"112 2","pages":"Article 102931"},"PeriodicalIF":0.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148738375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ichnoassemblage is assigned to the <em>Entobia</em> ichnofacies, a recurrent association typical of hard substrates such as boulders and oyster shells across a wide range of temporal and spatial settings. Taphonomic attributes and bioerosion patterns indicate that the oysters inhabited a shallow, nearshore, high-energy marine environment characterised by low sedimentation rates. Following death, the shells were likely transported downslope by storm-induced currents to a deeper shelf setting. The borings appear to have formed during multiple bioerosional phases, most of which occurred post-mortem and prior to final burial during the Tortonian.
