Naturalist Charles Pickering was the librarian and a curator of the Academy of Natural Sciences. In 1843, he traveled to Africa and India to research human races. In 1848, Pickering published Races of Man and Their Geographical Distribution, which enumerated eleven races.
It lived from 98 to 83 million years ago, separating itself from the Velociraptor by roughly 10 million years. You might say it's an ancestor of the actual Velociraptor, even though the original specie of raptor was almost the size of modern chicken and the Achillobator was roughly 1 ft taller than the average person.
Velociraptor is the 3 to 4 meter (10â13 foot) long, 2 meter (6 foot) high dromaeosaurid theropod carnivore that appears in all Jurassic Park films and film-based media. The Raptors are the main antagonists of the first film and the secondary antagonists of the second and third films.
