Prochelidella argentinae
Taxonomy
Prochelidella argentinae was named by Lapparent de Broin and de la Fuente (2001). Its type specimen is MACN-CH-1680, a partial shell (anterior part of a dorsal carapace, mostly in imprint, showing the anterior border and the three first pleurals and neurals. Preserved bony part of peripherals ), 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
| Reference | Diagnosis | |
|---|---|---|
| F. de Lapparent de Broin and M. S. de la Fuente 2001 | Same for the genus and species. Carapace low (a) and wide (B), with a slight cervical notch. Part of the Acanthochelys subgroup of the Phrynops group as shown by the small size and decoration; relatively derived within the Phrynops group by the quadrangular neural 1 and moderately narrowed cervical. Primitive with respect to Acanthochelys by the moderate elongation of the anterior border of the carapace (C1), the nuchal anteriorly and posteriorly wide (D2–3), the cervical less elongated and narrowed (E-), the presence of neurals (b) and the more anteriorly placed axillary processes (P). |
