Dinosaurs with Hair

I woke up this morning with one question on my mind.

"What if dinosaurs had hair?"

Is it so hard to imagine?
And, as follows by the dictates of logic, "What if dinosaurs grew beards?"
Also, one must ask, for the sake of posterity, "what if dinosaurs preferred mullets?"
or other fun and exotic styles?
What this ultimately amounts to is a fresh new challenge to the scientific community, if not an entirely new field of science all its own.

Get to work boys!
