The genus was described based on the external mold of a carapace and associated shell bone fragments found near the city of Tacuarembó, Uruguay.

[1] This fossil was found on the Tacuarembó Formation, whose estimated age ranges from late Jurassic to earliest Cretaceous.

[2] It is the first turtle to be discovered in South American continental deposits of that age, and shows a unique combination of traits (shared and derived), who allows the recognition of this fossil as a new genus.

Despite that, more remains are needed to clarify its phylogenetic relationships.

The histology of its plates, a shell that is dorsoventrally low, and the paleoenvironment proposed for the Tacuarembó Formation (permanent and temporary streams and lakes[2]), support the ecology of this genus as semiaquatic and mainly aquatic turtles.
