help me identify a game

[RaNkeri]

ok, so I remember that as a little kid I once played this beat 'em up style arcade game that had something to do with dinosaurs.

I especially remember a boss fight where this beefy badguy whacks a dinosaurus with two swords before he notices you and attacks you. I also remember that one of the playable characters was black, with yellow cap, green jacket and jeans, and another one was a brown haired muscle man.

Also, the game had many pick up-able items and weapons. One special item was a radio transmitter which allowed you to contact your friends, who'll give you a ride in a car for few secs, while running over all the bad guys during the ride.

Does this ring any bells?
