Raibliania

Raibliania is an extinct genus of tanystropheid archosauromorph discovered in the Calcare [del Predil Formation] in Italy. It lived during the Carnian stage of the Late Triassic and it was related to Tanystropheus. Raibliania is distinct from Tanystropheus due to some distinct features of the cervical vertebrae and teeth. The type species is Raibliania calligarisi, named in 2020. The holotype consists of a partial post-cranial skeleton, with the known elements including vertebrae, a single tooth, several ribs, gastralia and parts of the pelvis |ilium] and pubis.
In their [2024 description of Dinocephalosaurus material, Spiekman et al. suggested that the Raibliania fossil material may actually be referrable to Tanystropheus, due to notable similarities between skeletons of the two taxa. The results of their phylogenetic analysis, which included both Raibliania and Tanystropheus spp., are shown in the cladogram below:
