Artwork: Tyrannosaurs were generally small early on in their evolutionA newly discovered relative of Tyrannosaurus rex stood just over a metre tall at the hip, a study shows. The diminutive tyrannosaur reveals crucial new information about how T. rex established itself as a dominant carnivore in North America. Early in their evolution, tyrannosaurs were small, but at some stage, the hulking T. rex along with others emerged as apex predators. The new fossil helps fill a 70-million-year gap in the fossil record. Discovered in Emery County, Utah, the animal lived about 96 million years ago, during the later part of the Cretaceous Period. Tyrannosaurs, or "tyrant lizards" - the group to which this specimen and T. rex belong - ruled the predatory roost on land during the last 15 million years before the Chicxulub asteroid slammed into the Yucatan Peninsula 66 million years ago. T. rex could reach more than 3.5m tall as measured at the hip. Read:- www.bbc.co.uk/news/science-environment-47321411

If this Tyrannosaur lived around 96 million years ago, that would put it in the Cenomanian stage of the Early Cretaceous.
