Dinosaur's Superstars of Paleontology
Dinosaur National Monument is famous for its remarkable dinosaur quarry. Today, visitors have the opportunity to see the bones in-situ, which means that bones have been carefully exposed but left in the ground as they were found. However, in the early 1900s, the quarry was very active and many dinosaurs were removed, studied, and put on display. Even a century later, paleontologists come to Dinosaur to study and discover more information about dinosaurs and small animals that lived with them.
From the mighty sauropod (long necked dinosaur) to the fragments of the tiniest lizard bones, Dinosaur National Monument is full of fossil treasures that are both beautiful and scientifically fascinating. Join us on our virtual journey to learn about some of the best Dinosaur has to offer. If you enjoy reading about them, we hope you will join us here at Dinosaur or visit a museum near you to see some of our exquisite specimens.
