Pangea Software' Nanosaur II for modern systems
Nanosaur II: Hatchling is a continuation of the original Nanosaur storyline, only this time you get to fly a pterodactyl who's loaded with hi-tech weaponry. In addition to the three level adventure mode where you blast enemy dinos and save eggs, there are also six two-player levels including racing, capture-the-flag, and battle. This is a port of the original Mac version of the game to modern operating systems, made under permission from Pangea Software, Inc.
