Life reconstruction of the new tyrannosaur Timurlengia euotica in its environment 90 million years ago. It is accompanied by two flying reptiles (Azhdarcho longicollis). The fossilized remains of a new horse-sized dinosaur, Timurlengia euotica, reveal how Tyrannosaurus rex and its close relatives became top predators, according to a new study published in the Proceedings of the National Academy of Sciences.
