Plan an expedition to the Kamin Hall of Dinosaurs—Carnegie Museum of Natural History’s core exhibition featuring real dinosaur fossils.

This exhibition is home to dozens of original fossils from throughout the Mesozoic Era displayed in scientifically accurate reconstructions of their ancient habitats.

Are the Dinosaur Fossils on Display Real?

About 75% of the more than 230 objects on display are original fossils from one of the finest paleontological collections in the world, and most of the exhibition’s dinosaur skeletons are real, not replicas. Several of these skeletons—including those of the iconic dinosaurs Apatosaurus louisae, Diplodocus carnegii, and Tyrannosaurus rex—are holotypes, the original specimens upon which their respective species are based.

In the many decades since the discovery of Diplodocus, scientific interpretations of dinosaurs and their lifestyles have changed dramatically. This exhibition uses up-to-date paleontological evidence—much of which has been provided by the museum’s own scientists—to accurately reconstruct the appearance and behavior of these colossal creatures.

For instance, we now know that Apatosaurus and Diplodocus (two famous long-necked dinosaurs) did not spend their lives wallowing in swamps and that predatory dinosaurs such as T. rex walked with their tails held off the ground and their backs horizontal. The three-horned Triceratops may have used its famous headgear more for display than for fighting, whereas some theropod dinosaurs (such as Anzu wyliei, the notorious “Chicken from Hell”) would have closely resembled their modern descendants—modern birds.

Dinosaur Exhibition Layout

Many museum exhibitions group extinct species according to geologic time, but this exhibition takes this concept several steps further. In this exhibition, dinosaurs and other Mesozoic animals are shown in extraordinarily detailed reconstructions of their respective environments. Like the dinosaurs themselves, the habitats in this exhibition are firmly grounded in scientific evidence.

A panicked Apatosaurus smashes a small tree known from fossils found in the same Jurassic-aged rocks. A sculpted trackway of a hungry T. rex is based directly on the only known footprint of this terrifying meat-eater. The cat-sized Cretaceous mammal Didelphodon angrily confronts a much larger Triceratops. In short, in our museum’s exhibition, when dinosaur species are exhibited together, they actually lived together—their fossils are found in the same rock formations, and in many cases, the same quarries.
