What type of dinosaur is a Ornithomimus?
Ornithomimus, (genus Ornithomimus), ostrichlike feathered dinosaurs found as fossils in Mongolian, European, and North American deposits dating from 125 million to 66 million years ago during the Cretaceous Period.
Are Ornithomimus and Gallimimus the same?
Gallimimus is the largest known ornithomimid; adults were about 6 metres (20 ft) long, 1.9 metres (6 ft 3 in) tall at the hip and weighed about 440 kilograms (970 lb). As evidenced by its relative Ornithomimus, it would have had feathers. The head was small and light with large eyes that faced to the sides.

Did T Rex have hair?
rex had feathers that sprouted from its head, neck, and tail. What were its offspring like? Its hatchlings most likely were covered in fine hair akin to ducklings or chicks. Eventually, they would grow larger, retaining their feathers only on their head, neck, and tail.
Why did dinosaurs develop feathers?
A feathered dinosaur is any species of dinosaur possessing feathers. It has been suggested that feathers had originally evolved for the purposes of thermal insulation, as remains their purpose in the down feathers of infant birds today, prior to their eventual modification in birds into structures that support flight.
How fast can a Ornithomimus run?
Ornithomimus Could Sprint at Over 30 MPH Ornithomimus not only resembled an ostrich, but it presumably behaved like an ostrich as well, meaning it could hit sustained running speeds of about 30 miles per hour.
Did Ornithomimus eat eggs?
Though Ornithomimus are considered vegetarians, they occasionally ate meat, therefore, making them omnivorous dinosaurs; eating plants, meat, small reptiles and mammals, and even eggs.
Is the Ornithomimus a true bird mimic?

How did the Ornithomimus dinosaur get its name?
Ornithomimus was about 3.5 metres (11.5 feet) long, and, although it was a theropod dinosaur, it was likely omnivorous. Its name means “bird mimic,” and, like most other members of its subgroup (Ornithomimidae), it was toothless and had beaklike jaws. The small thin-boned skull had a large brain cavity.
Where is the best material of an Ornithomimus found?
The best material of species still considered part of the genus has been found in Alberta, Canada, representing the species O. edmontonicus, known from several skeletons from the early Maastrichtian Horseshoe Canyon Formation.
Why did the Ornithomimus have extra grey matter?
The most likely explanation for Ornithomimus’ extra grey matter is that this dinosaur needed to maintain its balance at high speeds, and may have had slightly enhanced smell, sight, and hearing. Mathew Brady (1822-1896) or w:en:Levin Corbin Handy (1855–1932) [Public domain], via Wikimedia Commons
