Meridiosaurus is an extinct genus of mesoeucrocodylian that is a possible member of the family Pholidosauridae.[1] Remains have been found in the Late Jurassic Tacuarembó Formation in Tacuarembó, Uruguay.[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 some authors, but a 2011 redescription and phylogenetic analysis confirmed the pholidosaurid classification of Meridiosaurus.[5][6]
