Last Killers
E3 Sep 28, 2011 30m TV-PG
A look at the last of the killer dinosaurs - carnivores that took killing to a new level. By the end of the Cretaceous period - 75 million years ago - these gigantic and specialised hunter-killers had spread throughout the globe. In the southern continents, it was the powerful and muscular abelisaurids that reigned supreme, but it was the famous tyrannosaurids (or tyrant dinosaurs) that dominated in the north.
