  Genus Struthiomimus
Struthiomimus was an dinosaur that lived in the late Cretaceous period, between about 76 and 74 million years ago.

Struthiomimus was about 14 feet (4.3 meters) long, and about 4½ (1.4 meters) tall at the hips. It is believed to have weighed around 330 pounds (150 kilograms). It was probably a fast-runner, perhaps being able to reach speeds of 30 to 50 miles per hour (50 to 80 kilometers per hour).

The first fossils of the animal were found by Othniel C. Marsh in 1890, and further fossils were discovered by Lawrence Lambe in 1901, and by Barnum Brown in 1914. The fossils found by Marsh and Lambe were believed by them to be a variety of Ornithomimus and were named accordingly - however after Barnum Brown's discovery of a near-complete specimen in Alberta, Canada in 1914, Henry Fairfield Osborn was able to identify this animal as a separate Genus and named in 1914, chosing the name "Struthiomimus" - which means "ostrich mimic".

As well as the confusion about classification, there has been considerable debate about the diet of Struthiomimus. Based on its straight-edged beak, some scientists believe it to have been an omnivore. Other scientists have thought it to be a carnivore (meat-eater), because some of its relatives were carnivores. Many scientists (including Henry Fairfield Osborn) have suggested Struthiomimus was probably a herbivore (plant-eaters) - its hands seem well-adapted to hooking branches and fern fronds. Finally, there is also a possibility that it may have lived on the shoreline and been a filter feeder, straining water for food particles in a way similar to modern flamingo birds.

Struthiomimus Facts

Here is a summary of some of the key facts about Struthiomimus:
  1. Struthiomimus was a genus of dinosaur.

  2. "Struthiomimus" means "ostrich mimic". This name was chosen by Henry Fairfield Osborn in 1917.

  3. Struthiomimus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Struthiomimus was not closely related to lizards, it did have similarly shaped pelvic bones.

  4. Struthiomimus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Struthiomimus was not itself an ancestor of birds).

  5. Struthiomimus lived between about 76 million years ago and 74 million years ago, during the late Cretaceous period.

  6. Struthiomimus lived in North America.

  7. Struthiomimus was probably an omnivore - although there have also been theories that it may have been a carnivore (meat-eater), herbivore (plant-eater), or even a filter feeder (straining food from water like a flamingo).

  8. Struthiomimus was about 14 feet (4.3 meters) long, and about 4½ (1.4 meters) tall at the hips.

  9. Struthiomimus weighed about 330 pounds (150 kilograms).
