One of the most well-known dinosaurs from the Triassic Period is Coelophysis, a small theropod dinosaur that lived in what is now the southwestern United States. Fossils of Coelophysis have been found in New Mexico and Arizona. Another notable dinosaur from this period is Sharovipteryx, a gliding reptile that lived in what is now Wyoming.
The Jurassic Period
The Jurassic Period lasted from 201 million to 145 million years ago. During this period, North America began to separate from other continents, forming the Gulf of Mexico and the Arctic Ocean. Many iconic dinosaurs lived during this period, including Stegosaurus, Allosaurus, and Diplodocus.
One of the most famous dinosaurs from the Jurassic Period is the long-necked sauropod Brachiosaurus, which lived in what is now Colorado. Another important dinosaur from this period is Archaeopteryx, a small bird-like dinosaur that is considered the link between dinosaurs and birds. Fossils of Archaeopteryx have been found in Germany, but its close relatives lived in North America.
The Cretaceous Period
The Cretaceous Period lasted from 145 million to 66 million years ago, and it was the last period of the Mesozoic Era. The climate during this period was warm and humid, and North America was divided by the western interior seaway, which stretched from the Arctic Ocean to the Gulf of Mexico. Many famous dinosaurs lived during this period, including Tyrannosaurus rex, Triceratops, and Velociraptor.
One of the most iconic North American dinosaurs from the Cretaceous Period is the horned dinosaur Triceratops, which lived in what is now Montana, Wyoming, and North Dakota.
