Podocnemis brasiliensis
Discussion
TYPE SPECIMEN: DGM 214-R in Price (1953: 12) but DGM 2980 in Candeiro et al. (2006: 927). Correct number is MCT 214-R (G.R. Oliveira, personal commun.). Partial plastron figured in Staesche (1937: fig. 1 [restored], pls. 16, 17) and Price (1953: figs. 1, 2.).
Taxonomy
Podocnemis brasiliensis was named by Staesche (1937). Its type specimen is MCT 214-R, a partial shell (partial plastron), and it is a 3D body fossil. Its type locality is Between Jupiá and Araçatuba (Km 101-104), which is in a Campanian/Maastrichtian terrestrial horizon in the Adamantina Formation of Brazil.
It was recombined as Bauruemys brasiliensis by Kischlat (1994), Romano and Azevedo (2007); it was considered a nomen dubium by Romano et al. (2013).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. P. Bogado et al. 2025 | “Podocnemis” brasiliensis can be diagnosed as a member of the Pleurodira because its plastron bears an anal notch and sutural attachments with the pelvic girdle. It is recognized as a member of the Pelomedusoides due to the presence of rounded paired mesoplastra that do not meet in the midline, and as a representative of the Pan-Podocnemididae owing to its elongated plastral bridge.
“Podocnemis” brasiliensis can be distinguished from other Pan-Podocnemididae due to the combination of the following characteristics: (1) shell surface with ornamentation composed of dichotomously branching shallow grooves, which may locally anastomose into an interconnected network (“pelomedusoid ornamentation” sensu Broin, 1977); (2) extragular scutes restricted to the epiplastra; (3) gular scute relatively narrow; (4) long midline contact between humeral scutes; (5) humero-pectoral sulcus departs from the midline at a posterior position, but progresses antero-laterally so as to nearly contact or slightly overlap the epiplastra; (6) pectorals reach entoplastra but not mesoplastra. |
