Beelzebufo, otherwise known as the “devil frog”, was an extinct species of giant frog that lived during the late Cretaceous period. It was one of the largest frogs ever to have existed and its fossils were first discovered in Madagascar. Unfortunately, this massive amphibian didn't survive into modern times and eventually went extinct due to a combination of factors. One possible reason for its extinction is climate change; as temperatures rose during the end of the Cretaceous period, Beelzebufo may have been unable to adapt quickly enough to survive in a drastically different environment. Additionally, scientists believe that competition with new species introduced by humans may also have played a role in its decline; it's theorized that human hunters encroached on Beelzebufo's habitat and hunted it out of existence. Ultimately though, we will never know exactly why this remarkable creature disappeared from our planet so long ago - but what we do know is that its unique size and features will not be seen again on earth anytime soon.
