A dinosaur from the cretacous period which had scorpion claws for hand. Coloured red and green and was one of the most dangerous things around. Liked to eat roarberries and spotted shrews (from which pigeons evolved from). Remains have been found in Texas and new Zealand
Now used to describe someone who has done something rediculous!
Ie - wow your such a scorpasaur!
Or - Scorpasaur! Man your crazy
