Ornithomimus, the “bird mimic” dinosaur, was a fascinating creature that roamed the earth during the Late Cretaceous period, approximately 74-66 million years ago.
With its bird-like appearance, long slender arms, and three-toed foot, it was a sight to behold.
The name Ornithomimus means “bird mimic” because of its striking resemblance to modern-day ostriches.
One of the most remarkable features of Ornithomimus was its speed. It was one of the fastest dinosaurs, capable of running up to 40 miles per hour.
This made it difficult for predators to catch and allowed it to outrun danger.
It also had a small, thin boned head with a large brain cavity and beak-like jaws, which suggests that it had a keen sense of sight and was a skilled hunter.
Despite its bird-like appearance, Ornithomimus was a dinosaur. It lived alongside other famous dinosaurs such as the T-Rex and Triceratops.
It was an omnivore, meaning it ate both plants and animals. Its diet consisted of leaves, fruits, insects, and small animals.
Ornithomimus was a fascinating creature with a unique appearance and remarkable abilities that continue to captivate scientists and dinosaur enthusiasts alike.
Discovering Ornithomimus
Ornithomimus, the “bird mimic” dinosaur, was first discovered in the late 19th century by the famous paleontologist Othniel Charles Marsh.
Since then, numerous fossils of this genus have been found across North America, shedding light on its unique characteristics and behaviors.
Fossil Finds Across North America
Fossil deposits of Ornithomimus have been found in various locations across Western North America, including Alberta, Colorado, and Wyoming.
The majority of these fossils were discovered in the Horseshoe Canyon Formation, Dinosaur Park Formation, and Denver Formation, which are all part of the Late Cretaceous period.
One of the most significant Ornithomimus fossils found in North America is the Ornithomimus velox, which was discovered in the Horseshoe Canyon Formation in Alberta.
This fossil is known for its exceptionally well-preserved skull, which has provided valuable insights into the dinosaur’s anatomy and behavior.
Unveiling the Ornithomimus Species
Over the years, several species of Ornithomimus have been identified, including Ornithomimus edmontonicus, which was first described in 1933.
However, some of these species, such as Ornithomimus elegans, are now considered nomen dubium, meaning that they are not considered valid species due to a lack of sufficient evidence.
Despite the ongoing debate surrounding the classification of Ornithomimus species, one thing is clear: these dinosaurs were fast and agile creatures, capable of reaching speeds of up to 40 miles per hour.
Their long, slender bodies, beak-like snouts, and slender limbs made them well-suited for running and hunting prey.
Fun Fact: Ornithomimus is often compared to its close relative, Dromiceiomimus, which means “emu mimic.” Both dinosaurs were known for their bird-like appearance and fast running speeds.
Anatomy and Appearance
The Bird-Like Features of Ornithomimus
Ornithomimus, a member of the Ornithomimidae family, was a toothless, bipedal, and slender theropod dinosaur that lived in the Late Cretaceous period.
It was about 12 feet long, 6 feet tall, and weighed around 300 pounds [1].
Ornithomimus had a long neck, a small head, and big eyes that gave it a bird-like appearance [1].
Its skull was small, thin-boned, and had a large brain cavity with beak-like jaws [2].
Ornithomimus also had a long tail, fingers, and forelimb that were adapted for speed and survival [2].
Its fingers were long and slender, and its forelimbs were short and powerful, which helped it to run faster and escape from predators [2].
Adaptations for Speed and Survival
Ornithomimus was a fast runner and had several adaptations that helped it to achieve and maintain high speeds.
It had a long neck that it used for display and balance while running [3].
Its long and slender legs had hollow bones, which made them lightweight and strong [1].
Its feet had three toes that were equipped with sharp claws, which helped it to grip the ground and run faster [2].
Additionally, Ornithomimus had a flexible spine that allowed it to make sudden turns and change directions quickly [2].
Its beak was toothless and lightweight, which made it easier for Ornithomimus to carry it while running [1].
Fun Fact: Ornithomimus was not the only “bird mimic” dinosaur.
Other members of the Ornithomimidae family with similar bird-like features include Struthiomimus (“ostrich mimic”) and Gallimimus (“chicken mimic”) [2].
Overall, Ornithomimus was a fascinating dinosaur with unique bird-like features and adaptations that allowed it to run fast and survive in its environment.

Diet and Behavior
Ornithomimus is a versatile omnivore, meaning it eats both plants and animals.
Its varied diet includes leaves, insects, lizards, small mammals, and even eggs.
The toothless beak of Ornithomimus suggests that it was adapted to feeding on soft, succulent plants and small animals.
Feeding Habits of a Versatile Omnivore
Ornithomimus had a varied diet and feeding habits. It was an agile and speedy dinosaur, which made it easier for it to catch prey.
Ornithomimus had a keen sense of smell and sight, which helped it locate food.
It was also able to run at high speeds, which allowed it to chase down prey and escape from predators.
Ornithomimus was able to feed on a wide range of food sources due to its omnivorous diet. It could eat plants, insects, and small animals.
It was also able to eat hard-shelled insects and seeds due to its powerful beak.
Social Lives and Survival Strategies
Ornithomimus lived in groups and had a complex social behavior.
It was believed that they lived in large herds, which provided them with protection from predators.
They were also able to share information about food sources and other resources.
Ornithomimus was able to survive in a wide range of habitats, including open plains and forests.
It was also able to adapt to different environments and feeding habits, which helped it survive for millions of years.
In conclusion, Ornithomimus was an omnivorous dinosaur with a varied diet and feeding habits.
It was able to survive in a wide range of habitats due to its agility and social behavior.
Its ability to adapt to different environments and feeding habits helped it survive for millions of years.
