A new archosauriform reptile from the Middle Triassic (Ladinian) of Germany.

Numerous well-preserved skeletal remains of a distinctive armoured archosauriform reptile from the Lower Keuper (Erfurt Formation; Middle Triassic: Ladinian: Longobardian) of Baden-Württemberg (Germany) represent a new taxon,Jaxtasuchus salomonigen. et sp. nov. The dermal armour ofJaxtasuchuscomprises transverse rows of four rectangular osteoderms each in the cervical, dorsal and caudal regions, with the individual plates closely resembling those ofDoswellia kaltenbachifrom Carnian strata in North America. The long and low maxilla ofJaxtasuchusheld at least 15 teeth. The labial and lingual surfaces of the tall, only slightly recurved crowns of the maxillary teeth bear distinct vertical ridges and smooth mesial and distal carinae. The cervical region of the vertebral column is long. Phylogenetic analysis placesJaxtasuchusas the sister taxon toDoswelliain DoswelliidaesensuDesojoet al. (2011). Doswelliidae is diagnosed by the coarsely reticulate, incised ornamentation of osteoderms composed of central regular pits of subequal size and contour, and a mostly smooth anterior articular lamina on each osteoderm. The discovery ofJaxtasuchusconfirms that Doswelliidae had a wide palaeogeographical distribution during the latter half of the Triassic. http://www.zoobank.org/urn:lsid:zoobank.org:pub:4A400628-07F3-4D1B-9CA8-336C379721FA [ABSTRACT FROM PUBLISHER]
