Beelzebufo ampinga or Devil Frog.


To begin the week and make it more bearable, I had thought about an animal today, very curious, which was discovered 4 or 5 years ago and that is the physical evidence of a fascinating event happened on Planet Earth. This animal is called "Beelzebufo ampinga".

Beelzebufo ampinga the Latin "Beelze" means devil, "bufo" means toad and "ampigna" means shield. It is the largest frog discovered in the world. Beelzebufo lived 70 million years ago in the Cretaceous in Madagascar. It shared the world with some known dinosaurs like T-Rex, and although it was no match for them, thanks to their huge mouths, could hunt small dinosaurs, babies and eggs, and other amphibians.


It measured just over 40 cm (16 in) and weighed 5 kg (10 lb), actually the largest frog is the Goliath, with 30 cm and 3 kg (6 lb). The ampingade Beelzebufo skull is composed of a thick shell and their teeth were strong and sharp. Its bite was very powerful and huge mouth, about 35 cm (12 in)  wide. The detail of its mouth is very important, its mouth was large compared to other frogs or toads, in fact it was this characteristic that served to classify this "frog" in the group of prehistoric "Pacman Frogs" or Ceratophrys, a group of frogs living in South America and have a big mouth. And here the controversy.
The earth 80 million years ago

How can it be that the "Pacman" are from South America andon the other hand, locate devil frog in Madagascar?
In principle this creates a contradiction. 70 million years ago, the continents had already split and although nearer than they are now, it would be impossible for terrestrial wildlife pass from one continent to another without encountering miles and miles of ocean. However, some experts think that there was a land connection between South America, Madagascar, Antarctica and possibly to some 65 to 70 million years. It's the only explanation, and if so, "continental drift" was not in order and not in the mode that we were taught in the representations.

Proterosuchus



This post refers to the end of the Permian (250 million years ago), just as is produced the great extinction that wiped out 95% of life that lived the Earth.

We talked a little moment in the history of the Earth, but that influenced the species appear in the next million years. Let us see:

It is thought that the Permian extinction was caused by the continued and exaggerated emanations of lava and gases that literally suffocated the Planet. Some events that ended with the great synapsids that ruled the prehistoric Earth, and they were a kind of curious animals, with characteristics of mammals, but reptiles ... some are called "mammal-reptiles".
The peculiarity of these animals is that they were warm-blooded. And although in principle we think this is an advantage over cold-blooded animals, the truth is that at the decisive point of extinction, was a real problem. We must consider that for an animal to keep warm blood should eat up to 20 times more calories than a cold-blooded animal. A treat for a time when food was becoming scarce.


In a world dark and wounded animals that died were the first warm-blooded. Instead of cold-blooded animals could resist. Now when entrael Proterosuchus in history.

The importance of the survival of this genus (Proterosuchus) is that, because it, envolved all the dinosaurs and birds we know today. If Proterosuchus not have survived, probably we would not know either the T.Rex, or to Spinosaurio, or the Argentinosaurus.

And how was this prehistoric animal?

Well, to get an idea, the Proterosuchus was similar to a three-meter crocodile. Hunted in ambush near streams and lakes. Like crocodiles, his eyes on the top of his head to stalk their prey. The snout ending in hook.

Finally, gender is Proterosuchus in the history of evolution, an individual as important as what could be the Pikaia or Ichthyostega.
