The Five Families of Dinosaurs: A Comprehensive Guide
T-Rex – The King of Dinosaurs
The Tyrannosaurus rex, or T-rex as it is more commonly known, is probably the most well-known dinosaur. Its fierce reputation and powerful jaws made it one of the dominate predators of the ancient world. But what many people may not know is that the T-rex is just one of five major families of dinosaurs that roamed the Earth millions of years ago.
Ornithomimosauria – 'The Bird Mimic Dinosaurs'
Ornithomimosaurs were a unique group of dinosaurs that were characterized by their long necks, long legs and smaller heads. They were also known for their 'strutting' gait, which seemed to give a bird-like motion. Fossils have been found in both North America and Asia.
Sauropods – The Largest and Most Heaviest of Dinosaurs
Sauropods, also known as the Brontosaurus, were some of the most massive dinosaurs ever to exist. These massive animals stood up to 50 feet in height and were some of the most massive animals to ever live on land. These incredible creatures powered through the ancient forests and plains, thanks to their four large and powerful legs.
Therizinosauria – The 'Scythe Claws'
Therizinosaurs were a unique breed of dinosaurs that featured incredibly long claws on their forelimbs. It is thought that these claws were used for self-defense, as well as for catching their prey. Fossil evidence suggests that these animals lived in both North and South America.
Theropods – Predatory Dinosaurs
Theropods were predators. They were not only fast, but they also had powerful claws that allowed them to catch and hold their prey. Fossils have been found on every continent, including Antarctica, which would have been unfrozen during the time of the dinosaurs.
Ankylosauria – The Armored Dinosaurs
Ankylosaurs were a unique breed of dinosaurs that featured a protective armor of bony plates and spines. This armor allowed them to protect themselves from predators and to defend themselves from attacks by other dinosaurs. Fossils of Ankylosauria have been found in North America, Europe, Asia, and Africa.
These five families of dinosaurs were just some of the creatures to inhabit the Earth during the age of the dinosaurs, but they are the ones that are most familiar and easily recognized by people today. While they left the planet millions of years ago, they live on through the fossils and other remains left behind, and in our imaginations.
