Moronosaurus

A Moronosaurus is The dumbest mammal on earth. The variation, Moronosaurus Rex, is the dumbest of the dumb.

Ever have someone that is so dumb it's mind numbing? They are most like a rare species of Moronosaurus.

That Don is such a moronosaurus. He can't do anything right.

If I have to listen to that moronosaurus one more time I think I might have to join the School of Dumbasses.

Morosaurus

A semi aquatic monster/dinosaur that comes out and beats kids with anything available. If it be a pole or a canoe paddle, no one is safe. A morosaurus is very protective of his turf and will defend it at any cost. If you ever run across a morosaurus, the only way to escape is to yell "You won't" or "Square Up" as loud as you can. He will see it as a very offensive act and will scurry off into the wilderness.

That creature looked alot like a morosaurus!
