It looks a bit poisonous, the Concavenator. That's probably because of its yellow-green lizard skin and the fiery red hump on its back. I wonder if it has a purpose other than scaring people. It's certainly impressive. The prehistoric giant's height of six meters also commands respect. But if you mess with it, you'll soon realize that the Concavenator isn't in the mood for fun: its powerful jaws open and close menacingly as it exposes his razor-sharp teeth. Time to head for the hills!
