Meridiosaurus is an extinct genus of mesoeucrocodylian that is a possible member of the family Pholidosauridae.[1] Remains have been found from an outcrop of the Tacuarembó Formation in Tacuarembó, Uruguay that dates back to the Early Cretaceous, but may also include very Late Jurassic strata as well.[2] The genus was described in 1980 on the basis of a partial rostrum that included the premaxillae and most of the maxillae.[3][4] The assignment to Pholidosauridae is considered doubtful by several paleontologists, such as R. Estes, A. Báez, and A. Mones (the first to name and describe the genus).[5]
