Paleo

Paleo documents the adventures of a little alien girl, Minna, who crashes her spaceship on pre-historic Earth upon running away from her home planet.

On Earth, Minna meets Umo, a distrusting, wild cave-boy, along with his shy pet dinosaur, Toro.

The illustration below, depicting the first meeting between Umo and Minna, was done on a whim, and eventually grew into this webcomic.
