20.500.12556/DiRROS-18378 Ornate Bairdiidae (Ostracoda) in 3 dimensions exploring carapace morphology and pore canals of Triebelina van den Bold, 1946, Nodobairdia Kollmann, 1963 and Mirabairdia Kollmann, 1963 Marine ostracods of the family Bairdiidae Sars, 1888 have an evolutionary history starting from the Ordovician with an explosive diversification of ornate forms during the Triassic. 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 ca- nals 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. ostracods ornate Bairdiidae morphology normal pore canals CT-scan 3D analysis ostrakodi Bairdiidae morfologija porni kanali CT-sken 3D analiza true false true Elsevier, Académie des sciences, Muséum national d'histoire naturelle Angleški jezik Francoski jezik © authors, 2024 Neznano 2024-03-08 13:58:53 2024-03-08 14:04:35 2024-03-12 03:35:33 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 7. 3. 2024; str. 137-159 Art. 23 (11) Mar. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-03-07 621.38 1777-571X 10.5852/cr-palevol2024v23a11 188082179 RAZ_Forel_Marie-Beatrice_2024.pdf RAZ_Forel_Marie-Beatrice_2024.pdf 1 053FC6E422475D2597CC9C7EFA7D0056 92638ebfa79b1caac8a3832ee78e970d08031f04f79d55aa375fa767c03fa7d6 7d6fd82e-dfa4-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25010 RAZ_Forel_Marie-Beatrice_2024.pdf RAZ_Forel_Marie-Beatrice_2024.pdf Za odpiranje datoteke potrebujete bralnik PDF, ki lahko odpre 3D datoteke.
