Scutosaurus

The Scutosaurus was a prehistoric animal whose name means "reptile shield", referring to the protective layer of the skin formed by bony plates that covered much of the body. Of course, this shield had a protective purpose, its aim was to keep intact the internal parts of the attack Scutosaurus the sharp teeth of his hunters. And this saurian predators tremendous teeth were similar to the saber-toothed tiger. Most were gorgonópsidos, family of which we speak when we name the Inostranceva. A predator which we discussed two weeks ago, LINK.

The Scutosaurus lived during the Permian, 250 million years ago, and their remains have been found in what is now Asia. A continent 250 million years ago, was part of the great supercontinent Pangea.


It was a very large herbivorous reptile. Heavy, more than 500 kg. Was 2.5 meters (8 ft,) long and 1.5 (5 ft.) high. Unlike other reptiles they have their feet on the sides of the body, the Scutosaurus had under its robust body in order to keep that huge weight concentrated. They were also short, so it is understood that not run very fast (certainly more than men). I had the legs on the trunk and they were short would give the less interesting look ... if we saw it from afar, may seem a boar that had taken growth hormones ... or better yet, a giant toad ... anyway. He also had two small horns emerging from its lower jaw and pointed down. The aim of these horns was to protect the neck from those predators who try to hurt the most fragile part of the body: the neck.


Permian These animals were very numerous and found numerous fossils can complete several skeletons. Would be something like the wildebeest of the African savannah. A very large number of wildebeest that serves as food for many of the predators of the savanna. But unlike the African wildebeest, the Scutosaurus lived in small groups, think. Since maintaining that rugged body continually needed to eat grass, and knowing that during the Permian as the main feature was the desert climate, it is thought that this ancient lizard had to travel long distances to find food. If they would formed very elevated groups, had ended with the vegetation of the area very quickly, forcing them to find another that could be fertile ground for miles ... being counterproductive.


The Inostrancevia.


The Permian period ended 250 million years ago, is the characteristic period of the great explosion of different vertebrates, also terrestrial wildlife and the emergence of future ancestors of mammals as we (and you too) and also the ancestors of past and prehistoric reptiles such as dinosaurs.

Our ancestor while superpredator of the Permian period was a Gorgonops (Gorgonopsid, a family of reptiles which is really more a mamíferol). How I explained earlier bad, if we saw a Gorgonops, probably would think it is a reptilian, but really its features are unique to mammals, such as hot blood ... in fact, it is considered our distant ancestor and that we are descended from it ... and you too.


Well, the largest Gorgonops, the superpredator of the period was the Inostrancevia (any of the 3 species). It was a hunter well developed, nearly 4 meters (13 ft.) in length. Intelligent compared with other creatures of the Permian. It walked to 4 legs, and moved similarly to the Komodo dragon, though its legs kept it at a slightly higher position and not dragged belly. Being able to reach higher speeds and close to 50 km / h.

The skull measured up to 50 cm and had teeth similar to the saber-toothed tiger ... fangs longer than about 15 cm, sharp and ready to hunt their prey. Besides its jaws were very powerful and with the force of its bite crossed Scutosaurus skin, the largest herbivore and was covered by a hard shell crossing.

Although extinct in the late Permian, about 250 million years ago, in the mass extinction of the Late Permian and early Triassic. We know enough of them. The numerous remains were discovered over 100 years ago in what is now Russia. And his name "Inostrancevia" refers to the famous Russian geologist A. Inostranceva.
