What Type of Dinosaur Skeleton Is Featured at the Smithsonian Museum of Natural History?

The Smithsonian Museum of Natural History is home to an extensive collection of dinosaur artifacts, including one of the most complete dinosaur skeletons ever discovered. This dinosaur skeleton is known as the Tyrannosaurus Rex and is undoubtedly one of the most popular exhibits in the museum.

The Tyrannosaurus Rex

The Tyrannosaurus Rex, also known as T-Rex, was a massive carnivorous dinosaur that lived over 65 million years ago during the Late Cretaceous period. It stood about 20 feet tall and measured up to 40 feet long, making it one of the largest land predators to have ever existed.

Appearance: The T-Rex had a large head and powerful jaws that were filled with sharp teeth. Its arms were relatively small compared to its massive body, and it had two powerful hind legs that allowed it to move quickly. The T-Rex’s bones were hollow and lightweight, making it easier for them to move around.

Discovery: The first T-Rex fossils were discovered in Montana in 1902 by paleontologist Barnum Brown. Since then, numerous fossilized remains of this species have been found across North America.

The Smithsonian’s T-Rex Skeleton

The T-Rex skeleton on display at the Smithsonian Museum of Natural History is named “Stan.” It is named after Stan Sacrison, who discovered the fossil in South Dakota in 1987. Stan’s skeleton is over 90% complete, making it one of the most well-preserved T-Rex skeletons in existence.

Size: The bones on display are not replicas but are actual fossils that were carefully excavated from their original location. The skeleton stands at an impressive height of over 12 feet tall and measures about 38 feet long from head to tail.

Exhibit: Visitors can view Stan’s skeleton in the museum’s David H. Koch Hall of Fossils – Deep Time exhibit. The exhibit features a range of fossils and interactive displays that allow visitors to learn more about the history of life on Earth.


The T-Rex is a fascinating dinosaur that captivates people of all ages. The Smithsonian Museum of Natural History’s T-Rex skeleton, Stan, offers an incredible opportunity to see one of the most complete and well-preserved dinosaur skeletons in the world.
