5. Ostrich-mimics (Ornithomimids)

Estimated Speed: 40 mph (64 km/h)


The Ostrich mimics refers to a group of dinosaurs collectively known as ornithomimids, which flourished in the late Cretaceous period. These dinosaurs generally had long legs, small bodies, and fierce facial features compared to modern ostriches. Although several genera of Gallimimus, Struthiomimus, and Dromiseiomimus were in this group, they all shared the same modifications for speed and agility

Ostrich mimics were among the fastest dinosaurs in the world, reaching speeds of 40 miles per hour or more. Their physical features, such as long hind limbs and lean bodies, contributed to their impressive speed. Despite their speed, they must have eaten a variety of foods, from plants to small animals.

These dinosaurs played an important role in Late Cretaceous ecosystems, populating geographical areas as scavengers and possibly as predators. Discoveries in places like Mongolia and North America have provided valuable information about their behavior, physiology, and role in the ancient ecosystems in which they lived.

6. Tyrannosaurus rex

Estimated Speed: 20 mph (32 km/h)

 Tyrannosaurus rex

Tyrannosaurus rex, often abbreviated as T. rex, is one of the most iconic and well-known dinosaurs that roamed the Earth during the Late Cretaceous period, approximately 66 to 68 million years ago. Renowned for its massive size, powerful jaws, and tiny, seemingly vestigial arms, T. rex was an apex predator in its ecosystem.

With an estimated length of up to 40 feet and standing about 15 feet tall, T. rex was an imposing figure. Despite its size, it wasn’t as fast as some smaller theropods, with an estimated top speed of around 20 mph. But it has been a formidable hunter, compensating for its lack of speed with impressive touch and sharp scent.
