Stokesosaurus was a small, early cousin of the mighty T. rex. It lived during the Late Jurassic period, about 150 million years ago, in what is now the United States. This speedy predator hunted small animals in a world full of giant sauropods and Allosaurus.1

Datos curiosos
Stokesosaurus is one of the earliest known tyrannosauroids, the group that later included T. rex.1
The only certain fossil of Stokesosaurus is a single hip bone (ilium) from a juvenile, about 22 centimeters (8.7 inches) long.1
Stokesosaurus lived alongside giants like Allosaurus, which made up 70 to 75 percent of the big predators in its environment.1
A tiny ilium from South Dakota may belong to Stokesosaurus, showing it lived far from Utah.2
Some scientists think Stokesosaurus might be the same animal as Tanycolagreus, but the missing hip bone of Tanycolagreus makes this hard to check.1
Stokesosaurus was named after geologist William Lee Stokes, who helped dig up thousands of Allosaurus bones at the Cleveland-Lloyd Quarry.1
