The fossil tooth is a remnant of an intense aerial attack between a double-spotted shark and lizard.
According to media reports, the animal has a sagging lower jaw, indicating that their mouths have pockets like pelicans, perhaps to catch fish and small reptiles.
Scientists have recently discovered the bones of nearly 50 winged reptiles of a new species, Caiuajara dobruskii, which lived during the Cretaceous period in Southern Brazil.
In movies, they flutter in the air with tremendous speed. But in fact, flying dinosaurs can hardly escape the ground because it is too heavy.
