Bonapartemys bajobarrealis

Osteichthyes - Testudines

Taxonomy
Bonapartemys bajobarrealis was named by Lapparent de Broin and de la Fuente (2001). Its type specimen is MACN-CH-1469, a set of postcrania (carapace, a right posterolateral part lacking, plastron less a right longitudinal part, part of girdles, limbs and tail), and it is a 3D body fossil. Its type locality is 6 km north of Estancia "Ocho Hermanos", which is in a Cenomanian/Turonian terrestrial sandstone in the Bajo Barreal Formation of Argentina.

Diagnosis
ReferenceDiagnosis
F. de Lapparent de Broin and M. S. de la Fuente 2001Same for the genus and species. Large ovale carapace, with an attenuated decoration, similar to large extant Phrynops, but with more primitive characters, given below. Apomorphic: posterior border of the carapace medially progressively elongated at peripherals 8–11; marginals 12 on the suprapygal, progressively medially elongated; vertebrals (V) 2 to 4 clearly narrowed, anteriorly as wide as posteriorly (V2=V3=V4); anteriorly narrowed intergular, elongated bridge. Plastral lobes are prolonged by a ridge at the bridge limit: the anterior lobe ridge particularly marked, up to the mesoplastra. B>PL>AL.
