Since the discovery of the first bones found in northwestern Madagascar in 1993, Krause and his team have gathered some 75 fossil fragments of Beelzebufo. Through the accumulation of these fossils, the team has been able to reconstruct the frog's skeleton, including nearly the entire skull.

Not only was the frog huge, it was powerful in design, had a protective shield, an extremely wide mouth and powerful jaws. These features made Beelzebufo capable of killing lizards and other small vertebrates, perhaps even hatchling dinosaurs. [emphasis added]
