Eotyrannus or “early tyrant” is a genus of tyrannosaur theropod dinosaur from the Early Cretaceous Period. It was discovered in the Wessex Formation, on the southwest coast of the Isle of Wight, UK. The remains were officially described in 2001.
Eotyrannus was roughly 20 feet in length. It was a fairly primitive tyrannosaur with elongated neck vertebrae and long, well-developed forelimbs. The dorsal surface of the skull was undecorated, unlike more advanced tyrannosaurs. This specimen has one of the longest hands of theropods known to date.
Eotyrannus most likely preyed upon herbivorous dinosaurs such as the Iguanodon, and other similar animals. The discovery of this tyrannosaur specimen in Europe makes an interesting case for determining the possible origins for these animals, along with other North American and Asian tyrannosaurid dinosaurs.
