Description

Crystal System: Hexagonal System Description: Phylum: Chordata Class: Reptilia Family: Ornithomimidae Common Name: Ornithomimus Age: Late Cretaceous Location: Denver Formation, Colorado Description: A very well preserved claw of the tip of the digit. Light brown in color. Physical Characteristics: Ornithomimus ( /??rn???'ma?m?s/; "bird mimic") is a genus of ornithomimid dinosaur from the Late Cretaceous Period of what is now North America. In 1890 Ornithomimus velox was named by Othniel Charles Marsh on the basis of a foot and partial hand from the Maastrichtian Denver Formation. Another seventeen species have been named since. Most of these have subsequently been assigned to new genera or shown to be not directly related to Ornithomimus. The best material of species still considered part of the genus has been found in Canada, representing the earlier Edmontonian-age Ornithomimus edmontonicus Sternberg 1933, known from several skeletons. However, on some of these the new genus Dromiceiomimus including Dromiceiomimus brevitertius (Parks 1926) has been based, causing taxonomic problems of priority and identity that are still unresolved. Ornithomimus was a relatively small swift bipedal animal, equipped with a small toothless beaked head, that may indicate an omnivorous diet.
