The retailer Crylophosaurus

Before Antarctica became a frozen wasteland, a ferocious predator prowled over the polar landscape. Crylophosaurus was a strong, stealthy killer, although it's bulky body prevented it from running fast for long. It probably hid among the trees, watching a heard of plant eaters and waiting for an opportunity to strike. When a likely victim came close, it would have made a short, high speed chase to seize its quarry, holding it with its huge clawed limbs and biting into the victim's neck with sharp, serrated teeth. On its head, Crylophosaurus sported a bizarre Crest and short horns, unlike any other prehistoric meat eater.
