Leyvachelys

Fossils of a turtle found in the dinosaur-rich Glen Rose Formation of Texas, informally named Glenrosechelys brooksi, have been assigned to the same genus and type species.

The section belongs to the middle segment of the Paja Formation called "Arcillolitas abigarradas Member" and has been dated on the basis of ammonites to be Late Barremian to Early Aptian in age.

Pliosaurs as Kronosaurus and Stenorhynchosaurus, ichthyosaurs as Muiscasaurus and Platypterygius and a plesiosaurs known as Callawayasaurus represent the known marine reptile fauna assemblage of the formation.

The abundant occurrence of molluscs, principally ammonites, some of them preserved associated with the carapace of L. cipadi, suppose a potential source of food for its durophagous diet adaptation which could have also included arthropods, as for example crabs.

[1] Fossil turtle fragments, initially and informally described as Glenrosechelys brooksi, found in the contemporaneous to slightly younger Glen Rose Formation of Texas have been assigned to the same genus Leyvachelys.
