Along the muddy rivers of Late Cretaceous Mongolia, a smaller predator stalks the shallows. Slender, sharp-toothed, and crowned with a row of bony crests, this is Alioramus altai—a cousin of the mighty Tyrannosaurus, but one built not for brute power, but for speed and precision. This dinosaur is looking for his next meal for the morning of the Cretaceous, finding small lizards or small herbivores as its meal.
