			We at Geologic Resources are fascinated by dinosaurs and since they no longer exist, have collected some pictures of reconstructed dinosaurs. The period of time (Geologic Time) known as the "Age of the Dinosaurs" was during the geologic Mesozoic Era which has been dated as from about 65 to 248 million years ago (USGS). Mesozoic time has been divided into three major periods: the first was named the Triassic Period, the second the Jurassic Period, and the third the Cretaceous Period. The Mesozoic Era was brought to a close by an episode of widespread diastrophism (mountain building and earth movement) known as the Laramian Revolution. The close of the Mesozoic Era has been called the "great dying out" because dinosaurs and many other life forms ceased to exist after this time (Stovall, et al, 1955).

Replicas of this species are present in nine museums around the world. The original reconstruction stands in the Carnegie Museum of Natural History's renowned Dinosaur Hall.
