Eotyrannus (meaning “Dawn Tyrant”) is a genus of tyrannosauroid from Early Cretaceous England.  It most likely hunted hypsilodontids like Valdosaurus. Neovenator and Baryonyx were both much larger than Eotyrannus. It may have had feathers or proto feathers, which is evidence that Tyrannosaurus may have had feathers, but Yutyrannus from China is a better example of tyrannosaurids having feathers.

The specimen is most likely a juvenile so the adult may have been larger. The species is E. Lengi, named by Hutt, in 2001. It is mostly related to Aviatyrannis from Europe and Stokesaurus from North America.
