It may have been a fish eater. Society of Vertebrate Paleontology Memoir 14. Madagascar has a diverse but mainly endemic frog fauna, the biogeographic history of which has generated intense debate, fueled by recent molecular phylogenetic analyses and the near absence of a fossil record. It grew up to over a metre tall and probably weighed anywhere from 400-600 kilograms (881 to 1322 pounds). It represents a lineage that evolved on Madagascar for over 20 million years and joins a litany of other bizarre Late Cretaceous vertebrate animals that we've found on the island. 40-47 in S. M.
