What Dinosaur Is in the Smithsonian Museum of Natural History?

If you’re a dinosaur enthusiast, the Smithsonian Museum of Natural History is a must-visit destination. This museum houses one of the largest collections of dinosaur fossils in the world. In this article, we’ll take a closer look at one of the most famous dinosaurs in the museum’s collection – The Tyrannosaurus Rex.

The Tyrannosaurus Rex

The Tyrannosaurus Rex, also known as T-Rex, is arguably the most famous dinosaur species in history. This massive predator lived during the Late Cretaceous period, around 68 to 66 million years ago. It was one of the last dinosaurs to go extinct before the asteroid impact that wiped out all non-avian dinosaurs.

Physical Characteristics

The T-Rex was one of the largest carnivorous dinosaurs ever discovered. It stood up to 20 feet tall and weighed around 9 tons.

Its long and powerful tail helped it maintain balance while running at speeds of up to 20 miles per hour. The T-Rex had strong legs with sharp claws that could grip and tear prey apart.

One of its most distinctive features was its massive head, which was almost five feet long and filled with dozens of sharp teeth up to 12 inches long! Its jaws could exert a force of over 12,000 pounds per square inch – enough to crush bones with ease.


The first T-Rex fossil was discovered by paleontologist Barnum Brown in Montana in 1902. Since then, hundreds of T-Rex fossils have been found across North America.

The Smithsonian’s T-Rex specimen is named “Stan,” after Stan Sacrison, who discovered it in South Dakota in 1987. Stan’s skeleton is over 40 feet long and nearly complete – missing only a few bones from its tail and feet.


The T-Rex skeleton is displayed in the museum’s David H. Koch Hall of Fossils – Deep Time exhibit. The exhibit features a range of other dinosaur fossils and interactive exhibits that showcase the history of life on Earth.

Visitors can get an up-close view of Stan’s skeleton, which is mounted in a dramatic pose with its mouth open and teeth bared. The exhibit also includes a life-size model of a T-Rex skull, allowing visitors to see just how massive this dinosaur’s head was.


The Tyrannosaurus Rex is one of the most famous dinosaurs in history, and for good reason. Its massive size, fearsome appearance, and impressive hunting abilities have captivated the imaginations of people for generations.
