To be a Velociraptor dromaeosaurid was relatively small, the adults reach a length of 2 m, and approximately 0.5 meters in height at the hip, and weighing about 15 kg. The skull, about 25 cm long, was uniquely up-curved, with a concave upper surface and a convex bottom. The jaws were lined with 26 or 28 teeth on each side, the rear edge of each tooth was markedly serrated.
But of all the features that made the Velociraptor a murderer efficient and sharp curved claws were the most dangerous. Located on the second toe of each foot, these claws were a fine point and were flattened laterally, like the claws of a cat. When the Velociraptor ran, stretched claws held back so as not touching the ground and did not lose their edge.
When the Velociraptor attack, the claw could project forward and down while HADB a strong kick. Thus, the claw could act as a razor-sharp knife and result in protracted and deep cuts in their prey, probably bleed to death.
Velociraptor is well known in his role as a cruel and cunning murderer may attack small offspring from larger dinosaurs such as Triceratops.

Velociraptor (meaning "swift thief") in Castilian Velociraptor, is a dromaeosaurid theropod dinosaur that lived during the Campanian to the late Cretaceous period, makes about 70 to 65 million years. On the mainland, which is in Europe and Asia.


This was a robust animal prehistoric herbivore that could switch between bipedal to quadrupedal. The well-known species, I. bernissartensis, it is estimated that weighed about 3 tons on average, and measure about 10 feet long when adult, with some specimens possibly would have reached 13 meters.
The arms were long, up to 75% of the length of the legs with inflexible hands built so that the three central fingers could bear weight.

One of the first details on the iguanodons noticed was that I had reptile herbivore teeth (Iguanodon means "Iguana tooth" as they were of a similar but larger and with a greater destructive capacity) although there was not always consensus on how to eat .

There is no evidence to support a sexual dimorphism, as in hadrosaurs and Ceratopsia.

It is thought that they lived in herds of several dozen individuals as fossils have been found in certain circumstances, several bodies Iguanadon in ancient lakes or rivers, possibly due to the flood of these during migration.

They lived in the early Cretaceous period, makes about 130 to 120 million years (mong the Berriasian and Aptian) in what is now Europe. And in North America.

The scion of thumb is one of the best known features of the iguanodons. Yet it was placed, initially, in the nose by Mantell. When they found the complete copies in Bernissart Dollo realized the mistake and I put in place fingerprint, thumb amended.
