With its length of six meters, the concavenator has an imposing appearance. His lizard skin glows grass green and yellow. There is an elongated bump on his back that stands out red against the rest of his body. With his striking appearance he keeps enemies at a distance. And when they do approach, he shows his sharp teeth. There is no predator that will not run away. The concavenator looks quite poisonous. That's probably because of that yellow-green lizard skin and the bright red bump on its back. What is it for? No idea, but it does make an impression. This prehistoric giant also commands respect with its six meters length. If you want to compete against him, you will quickly notice that he does not like jokes. He then opens his powerful jaws threateningly and shows his razor-sharp teeth. Get out!
