The epanterias Amplexus was probably the greatest of all Allosaurus. I say probably because many experts do not consider the rest found, the rest of a different species to allosauros. But this confusion is normal, the only bones that have been found are, 3 vertebrae a coracoid (a part of the body near the shoulder) and a metatarsal (a finger). Of these fossils, after analyzing the experts, it has concluded that they were Allosaurus, which were quite large, even more than the Saurophaganax or Allosaurus fragilis.
The epanterias Amplexus was a theropod (like almost all theropods, bipedal carnivores) allosaurid North America who lived around 150 million years ago ... in the Jurassic.
As to its dimensionsthe measures vary between 12 (39 ft) and 16 meters (52 ft.). Respectively, the first estimate corresponds to those who think that it was only a large Allosaurus fragilis. The measurements between 14 and 16 meters are estimates of those who believe that are treated rather of a different species.
Take for example the case of T. Rex. The Rex measures 12.5 (42 ft.)meters in length. Instead the epanterias Amplexus can reach 14 (45 ft.) meters according to some estimates, however, the most conservative support could reach 12 meters (39 ft.).
The height of one and the other is about 4 meters (13 ft.)high to the hips. If set upright likely it reaches 6 meters. And if we calculate the weight, this would approach between 4 and 5 tonnes (2250 lb.).
Only seeing the data we get an idea of their proportions. In fact, it is considered the longest of all allosáuridos, and larger and heavier than the Allosaurus fragilis ... if he really is a different species allosaurido.
If we saw to it quickly, clearly we would see the differences between epanterias Amplexus the T.Rex. For example, the first has smaller than the second head. Another characteristic feature is that the T.Rex has little arms, however the epanterias Amplexus has a longer and arms with huge claws.
If we had X-ray eyes, we would see that the T. Rex skull is more compact, its bite was stronger. Instead, the epanterias Amplexus had a lighter skull, but the top of his skull was secure with a powerful neck and would aim a bite with the upper teeth as an ax.
Among its favorite foods we would find Camptosaurus, Diplodocus and Stegosaurus ... of the greatest of all herbivores.
