Vertebrate Paleofauna
Animals found in the formation include frogs (including Beelzebufo ampinga), turtles, snakes, lizards, at least seven species of crocodyliforms (including species of Mahajangasuchus and Trematochampsa), abelisaurid theropod Majungasaurus, noasaurid Masiakosaurus, two types of titanosaurian sauropods (Rapetosaurus and an unnamed second form), and at least five species of birds or very bird-like dinosaurs, including Rahonavis. The 6 to 7 meter long (20 to 23 ft) Majungasaurus was likely the apex predator in the terrestrial environment. Crocodyliforms were very diverse and abundant.
