Prochelidella buitreraensis is known from the Huincul Formation of Argentina.[3] Its specific epithet references the paleontological site La Buitrera, where its fossils were discovered.[5]
The remains are notable for their exceptional state of preservation, which includes the presence of the skull. Besides, the remains of cervical vertebrae, the shell and the appendicular skeleton have also been found. The remains were found in Cañadón de las Tortugas, at La Buitrera, Río Negro Province, Argentine Patagonia, by scientists from CONICET. The estimated age of the finding, from the Cenomanian age, was calculated with radiometric dating carried out on zircons on a volcanic tuff. The remains of Prochelydella buitreraensis are hosted at Carlos Ameghino Provincial Museum in the city of Cipolletti, Río Negro Province, Argentina.[3] Its discovery appears to show that turtles and tortoises at some point in their early history were incapable of hiding their heads into their shells.[6]
