Dinosaur Walk Museum Period almost 210 million years ago. It grew to be between 2–3 meters in length and less than a meter tall at the hips. Coelophysis had an unusual formation in the vertebrae, forming an "S" like shape in its neck. It is the ""official dinosaur"" of New York State. Velociraptor: Living during the late Cretaceous Period, 83-70 million years ago. The Velociraptor, a carnivore, grew to be up to in length and could grow up to 45 pounds. The Velociraptors had on their feet long curved claws used for attacking their prey. They had a bone structure similar to many
Nothronychus upright than its carnivore ancestors. "N. graffami" weighed about a tonne, were 4.5–6 m (15–20 ft) long and stood 3-3.6 m (10–12 ft) tall, while "N. mckinleyi" was only slightly smaller. A reconstruction of 40 to 50 percent of its skeleton, from the two separate species, allowed scientists to describe these dinosaurs as having leaf-shaped teeth with circular roots, long necks, long arms with dexterous hands and, measured over the curve, up to thirty centimeter (12 in) long curved claws on their fingers, large "pot-bellied" abdomens, stout hind legs, and relatively short tails. "N. mckinleyi" was different from "N. graffami"
