Maganuco S. & Pasini G., 2009 - A new specimen of trematosaurian temnospondyl from the Lower Triassic of NW Madagascar, with remarks on palatal anatomy and taxonomic affinities. Atti Soc. it. Sci. nat. Museo civ. Stor. nat. Milano, 150 (I): 91-112.
Abstract - A new partial skull (preserved as a natural mould) of a trematosaurid temnospondyl fromthe Lower Triassic of the Ankitokazo Basin, Diégo Suarez Province, NW Madagascar, is described. It provides new information on the palatal anatomy, poorly known in the Malagasy trematosaurids, the more important concerning the morphology of the cultriform process, which is squared in cross section and comparatively wide. The new specimen represents a taxon well distinct from both Malagasy lonchorhynchine trematosaurid Wantzosaurus elongatus and other trematosaurid genera known out of Madagascar. The taxonomic and phylogenetic affi nities found between the new skull and all the Malagasy non-lonchorhynchine specimens so far described suggest that the material may belong to a single species, closely related to the German species Trematolestes hagdorni, and more similar to Tertrema acuta than to Trematosaurus brauni. The new skull is therefore tentatively referred to cf. Tertremoides madagascariensis, the only non-lonchorhynchine trematosaurid species from Madagascar that we regard as valid, following the systematic review by Schoch & Milner (2000).
