Discover authentic dinosaur fossils including T. rex, Triceratops, Apatosaurus, Atlasaurus, eggs, and coprolite. Hold prehistory in your hands.

The "dinosaur bones" that you see on display at the Museum aren't really bones at all. Through the process of fossilization, ancient animal bones are turned into rock.

We offer a wide range of dinosaur fossils for sale, including dinosaur teeth, dinosaur bones, and dinosaur claws. All of the material we offer has been legally collected and can be legally sold.

Eastern dinosaurs come from the rift valleys of the Late Triassic and Early Jurassic, and coastal areas of the much higher seas of the Cretaceous. We can see this pattern in a map of National Park Service units with dinosaur fossils, which are concentrated in and around the Colorado Plateau (Four Corners states).

The Mesozoic Era is further divided into three Periods: the Triassic, the Jurassic, and the Cretaceous. Park fossils document dinosaurs from the Late Triassic (approximately 210 million years ago) to the end of the Cretaceous (66 million years ago).

July 8, 2022 - Think mostly sand, silt, mud, and pebbles, with some cases of chemical deposition of lime, or marine “rain” of tiny plankton pieces. Most dinosaur fossils are found in rocks deposited by ancient rivers, because the rivers moved enough sediment ...

4 days ago - They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya.

April 3, 2025 - Above: An artist’s depiction of the massive fossil! The first near-complete dinosaur skeleton, this Hadrosaur was a major milestone in the field of paleontology!

A fish fossil. Nearly all fossils we find are from marine animals because sediments like mud and sand quickly bury their remains. The most common way an animal such as a dinosaur fossilises is called petrification.

October 30, 2025 - Skeletons of duck-billed dinosaurs found more than 100 years ago are so well-preserved that they contain fleshy body parts of the extinct species embedded in thin layers of clay, scientists say. Specimens of Edmontosaurus annectens, known for their long skull that resembles a duck's bill, were found in eastern Wyoming in the early 1900s. Recent reexamination of those fossils by paleontologists at the University of Chicago revealed that the fossils do not contain just bones, but mummified body parts protected underneath a clay mask, according to a paper published last week in Science.

1 day ago - Some fossils are so exciting that when first shown at academic conferences, they draw audible gasps even from experienced palaeontologists. Zavacephale is one of these. The stunning skeleton of this one-metre-long plant-eating dinosaur was discovered in 110-million-year-old rocks in the Gobi Desert of Mongolia and described by palaeontologist Tsogtbaatar Chinzorig and colleagues.
