The time when Dinosaurs roamed, the Age of the Reptiles.
"Isn't that dinosaur skeleton from prehistoric times?"

a slang term used to describe an obvious lesbian. She is described as prehistoric because she is a direct descendant of a "Lick-alotta-puss". Lipstick lesbians are not prehistoric because they are not easily picked out as a dyke
Dude, look at that dyke playing 3'rd base with the short ass hair, she dives for every ball like she's diving for muff. She's prehistoric.
