PaleoDB taxon number: 65907
Under the current state of knowledge, it may appear superfluous to maintain the name Thalassemydidae because it is redundant with Thalassemys at the moment. However, the phylogenetic relationships of Thalassemys spp. with other thalassochelydians have never been properly explored. One of the main reasons for this is the absence of cranial material for thalassemydids. Pending better understanding of thalassochelydian relationships, we maintain the use of the name Thalassemydidae for practical reasons, but, once again highlight its taxonomic ambiguity through the use of quotation marks.
