Top row: Partial braincase of Timurlengia euotica in tree views (L to R: from the back, from below, and from the right side). Bottom row: Composite images of the brain case from CT scanning. Reconstructed brain in dark blue, inner ear in pink, nerves in yellow, and blood vessel in red. 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.
