Dinosaurs in Their Time

From dinosaurs to birds and millions of years in between, there is always something to sink your teeth into at Carnegie Museum of Natural History.


Dinosaurs in Their Time is the first permanent exhibition in the world to feature scientifically accurate, immersive environments spanning the Mesozoic Era—the Age of Dinosaurs—arranged chronologically and filled with actively posed original fossil specimens. See dinosaurs like they haven’t been seen in 66 million years!

Nearly 75% of the exhibits are composed of actual fossils from one of the finest dinosaur collections in the world. Plan an expedition to Dinosaurs in their Time to examine these real fossils, just like our paleontologists do!


In the century since the discovery of Diplodocus carnegii, scientific interpretations of dinosaurs and their lives have changed remarkably. Dinosaurs in Their Time is a dramatic exhibit arena that reflects current scientific evidence of these colossal creatures and their environments. For instance, we now know that Diplodocus did not drag its tail through Jurassic swamps, and the sheer size of Tyrannosaurus rex casts a shadow of doubt on its reputation as a Cretaceous killing machine.

The continental and climatic changes that affected the evolution of species over time are also addressed as well as the other extraordinary life forms that shared their environment, including birds, fish, amphibians, turtles, plants, and even mammals. The museum's vast fossil collections, combined with its scientific expertise, guarantee an exhibition that accurately interprets the incredible record prehistoric animals left behind and integrates the dinosaurs into the ancient ecosystems in which they lived.


  • Visitors can witness dinosaur fossils and other prehistoric creatures being prepared for exhibit and study in PaleoLab.
  • Experience the thrill of unearthing dinosaur and mammal fossils casts in our hands-on interactive fossil dig, Bonehunters Quarry.
  • Explore more than 300 pages of scientific content on 20 interactive touchscreens for in-depth information on the creatures and dioramas in the exhibition.

Did You Know?

Dinosaurs lived from about 225 to 65 million years ago, during the Mesozoic Era. In that tremendous span of time, a great variety of dinosaurs evolved—over 370 species of these "terrible lizards" have been named. Cenozoic Hall, the Hall of Fossil Mammals provides information on the Age of Mammals, which followed the dinosaurs.

The 78-foot-long Diplodocus was one of the longest animals that walked the Earth, and the more famous Apatosaurus, formerly known as Brontosaurus, nearly equals it in length.
