Velociraptor was a mid-sized dromaeosaurid. Adults measured up to 6 ft 9.5" long and 1 ft 7.5" high at the hip. and weighing up to 33 pounds. The skull could grow up to 10" long. They jad 26 to 28 widely spaced teeth on both sides of their jaw. Their teeth were more serrated on the back edge than on the front edge.
Velociraptor, like other dromaeosaurids, had a large hand with three curved claws. There hands were similar in construction and flexibility to the wing bones of modern birds. The second digit was the longest of the three digits and the first was the shortest. The first digit of the foot, was a small dewclaw. Dromaeosaurids like Velociraptor walked on their third and fourth digits. They held their second digit retracted off the ground. It jad a relatively large, sickle-shaped claw. This claw, which could grow to over 2.5" long around its outer edge was most likely used to take down it's prey.
The Hell Creek Formation is an intensely-studied division of Upper Cretaceous to lower Paleocene rocks in North America, named for exposures studied along Hell Creek, near Jordan, Montana.
The Hell Creek Formation occurs in Montana and portions of North Dakota, South Dakota, and Wyoming.
Strata in Hell Creek a series of fresh and brackish-water clays, mudstones, and sandstones deposited during the Maastrichtian, the last part of the Cretaceous period, by fluvial activity in fluctuating river channels and deltas and very occasional peaty swamp deposits along the low-lying eastern continental margin fronting the late Cretaceous Western Interior Seaway. The climate was mild, and the presence of crocodilians suggests a sub-tropical climate, with no prolonged annual cold. The famous iridium-enriched K–T boundary, which separates the Cretaceous from the Cenozoic, occurs as a discontinuous but distinct thin marker bedding within the Formation, near its uppermost strata.
