A giant lizard is drawing on a cave wall. Two cavemen are spying on him.
Lizards don't have opposable thumbs and can't draw pictures.
Who lives in that cave?
It will be worth even more when he's extinct.

This joke takes the common trope of an artist's work rising in value after they die to an extreme: instead of the lizard's art rising in value when the lizard dies, it rises in value after the entire lizard species is extinct. Extinction also fits in with the trope of cave-people/ancient times/dinosaurs.
