A new species of dinosaur that looks like a mini T-Rex has been discovered by scientists in New Mexico, America.
It's called 'Tawa hallae' after the native American god of the sun.
Scientists are excited about the find, as it tells them more about how dinosaurs evolved in North and South America, and spread around the world.
The dinosaur is two meters long, has sharp ridged teeth like a steak knife, and would have lived in the late Triassic period 213 million years ago.

Tawa hallae is a distant relative of the T.rex and Velociraptor and would have walked on its back legs.
When Tawa hallae was alive North and South America were joined up into a super continent called Pangaea.
Some scientists think dinosaurs originated on this massive continent, and then spread around the world.
