Resumen
We provide a detailed description of the poorly known reptile Eifelosaurus triadicus Jaekel, 1904 from the Upper Buntsandstein (Triassic: early Anisian) of Oberbettingen in the southwestern Eifel region of Rhineland-Palatinate, Germany. The holotype and only known specimen is a partial postcranial skeleton exposed in ventral view. Since its original description Eifelosaurus triadicus has been almost completely ignored in the literature. Our phylogenetic analysis recovered this taxon within Rhynchosauria and Rhynchosauridae, as the sister taxon to the clade comprising Stenaulorhynchinae and hyperodapedontine-line rhynchosaurids. A unique combination of character states allows distinguishing Eifelosaurus triadicus from other rhynchosaur species with preserved matching postcranial bones. Thus, we tentatively consider this taxon valid until more information about the postcrania of other Early to Middle Triassic rhynchosaurs becomes available. Eifelosaurus triadicus represents a paleobiogeographically important record, showing that rhynchosaurs had already attained a broad paleolatitudinal distribution by the early Middle Triassic.
