Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Sarda and I. Maniel 2024 | Baalemys mansillai (MUC-Pv 2169) can be diagnosed as Chelidae by the combination of the following characteristics: a cervical scute, presence of a pectoral scute behind the entoplastron, mesoplastra which are wider than long, a narrow posterior lobe, only one suprapygal bone, and pleural scutes wider than vertebral scutes. It can be distinguished from all extant chelids by the presence of mesoplastra. Baalemys mansillai differs from Prochelidella portezuelae by having the first hexagonal neural with short posterolateral sides, the second neural shaped like a regular hexagon, and a narrow posterior plastral lobe. It can be differentiated from all Cretaceous chelids of the Neuquén Basin by its granulated ornamentation. Finally, it presents this unique combination of characters: granulated ornamentation, moderate size, dome-shaped shell; first hexagonal neural with short posterolateral sides, second hexagonal neural, narrow nuchal, and a plastron with the anterior lobe > posterior lobe > bridge. |
