Well, this is a very random question. Anyway, he'd just about get gobbled up by any large carnivore like T.rex, Spinosaurus and the Indominus. A kitchen knife won't do much against a 10 ton behemoth. A pack of Raptors would overwhelm him, but a single velociraptor against the shape would make for a good fight. Michael could use his supernatural strength to stab the raptor at a vital organ.
