"Oxalaia" shared this habitat with many different kinds of animals. Other dinosaurs found in the formation included giant carnivores like "Carcharodontosaurus", and perhaps "Spinosaurus". Smaller predators lived there too, such as dromaeosaurids, and an animal very similar to "Masiakasaurus". There were also large sauropods, a group of herbivorous (plant-eating) dinosaurs. Fish found in the formation included bony fish, ray-finned fish, and lungfish. There were also giant coelacanths and sawfishes. Besides dinosaurs, there were other reptiles, like pterosaurs and crocodilians. Fossils of snakes and molluscs have also been found.
