A List of Omnivorous Dinosaurs: What Is It?

Anserimimus, Deinocheirus, Gallimimus, and Othnielia are examples of omnivorous dinosaurs. A tiny dinosaur called Fruitadens haagarorum was found to be omnivorous because to the existence of both canine-like, cutting teeth and leaf-shaped, plant-grinding teeth. It showed a change in feeding from its earlier herbivorous ancestors as a heterdontosaurid.

Early maniraptor lineages changed their diets to become more omnivorous. These included seedeaters like some troodontids, avialans, and insect eaters like alvarezsaurs.

Gallimimus, Shenzhousaurus, and Ornithomimus were some of the ornithomimosaurs, commonly referred to as ostrich dinosaurs, that existed during the Cretaceous Period. Some possessed teeth, but the majority had beaks, large upper limbs with hoof-like claws, and lengthy legs. Ornithomimosaurs, according to scientists, were among the quickest runners of all dinosaurs and consumed primarily plants and tiny animals.

The Late Cretaceous ornithomimid Anserimimus was a swift runner with powerful front limbs. It stood out from related species due to its strongly built forelimbs and slightly curled claws. It was most closely related to Gallimimus.

Ornithomimids, which originated from carnivores, were likely omnivores or even herbivores, according to scientific theory. Gallimimus, which is Latin for “rooster” or “chicken mimic,” resembled modern birds in that it possessed hollow bones and eyes on the sides of its head.
