Lacusovagus was a large pterasaur from Brazil during the Early Cretaceous. It hunted over the land instead of the water like other pterasaurs. It would eat mostly small prey like reptiles and baby dinosaurs. At the time of its discovery, Lacusovagus was the largest pterasaur to be discovered in Crato Formation. Like all pterasaurs its wings where made of three long stretched finger bones and a tiny layer of skin is stretched across them to give it support in the air. As well as hollow bones to make the dinosaur light.
