On the third instalment of this series of ranking mega-theropod dinosaurs, we’ll be looking at the North American species Acrocanthosaurus atokensis, known as the high spined lizard.
This guy is probably not everyone’s first choice for a large carnivorous dinosaur, but I was thinking of making an episode on this guy around the same time I started writing the Tarbosaurus script, so let’s get started.
