Razanandrongobe (meaning "large ancestor lizard" in Malagasy) is a genus of carnivorous archosaurian reptile of uncertain affinities from the Middle Jurassic of Madagascar. It is based on MSNM V5770, a fragment of maxilla, the main tooth-bearing bone of the upper jaw, and several isolated teeth have also been assigned to it. The remains come from the Bathonian-age Isalo Illb rock unit of Mahajanga. The jaw fragment and teeth are similar to the representative bones of theropod dinosaurs and some types of crocodylomorphs, and the authors refrained from assigning the genus to either group. They interpreted the stout teeth as having been used for crushing bones.[1] The fragment suggests a considerable size for the species, comparable to that of Tyrannosaurus.
