Austroraptor

 




The Austroraptor is a close relative to Velociraptor, but larger, about 20 feet long (3 times longer). His name means "thief of the South" (South raptor), such as birds, and do not put this name by chance. In a way, his appearance might remind us old birds, a predecessor to the Raptors next we Know today. His head (over 4 fts) was low, long and streamlined, provided with numerous small and conical teeth. Moreover, according to the markings found in fossils, it was covered with feathers.

This prehistoric animal called attention to the paleontologist who discovered it to see how their upper limbs were in proportion smaller than others of the same gender: their short forearms depart from the condition characteristic of all long arms and their relatives dromaeosaurids avian nearby. This would therefore be a missing link between dinosaurs and modern birds.
  Perhaps (and this is my opinion) is an example of regression, this means that they resumed their oldest species characteristics. As is the case of flightless birds also reduce its wings.

Instead, it was her hind legs which facilitated the classification of this new species, the family Dromaeosauridae or "corridors lizards." By this I mean that was a fast runner Austroraptor, who had strong back legs and he used to hunt their prey.

The Austroraptor lived 70 million years in the late Cretaceous period in what is now South America..
