Pangea Software, the company that brought us Bugdom, developed and published Nanosaur in 1998. In Nanosaur, dinosaurs have been reproduced by scientists. Shortly afterwards, the human race died out from a plague of some sort. You play as a dinosaur sent sixty-five million years back in time to collect dinosaur eggs before the asteroid hits Earth, wiping out all the dinosaurs.
Three versions are now included: v1.0, v1.0.6 & v1.1.6.
Repackaged the broken Nanosaur 1.1.6 archive from here and removed all traces of OS X hidden files from the archive. Now it is a compressed ".sit" Stuffit 5.5 archive enclosing a locked Disk Copy 6.3 image file. Also have included with this archive the original Nanosaur version 1.0 with a 1.0.6 updater for those who would like to try the original - this can run on Mac OS 8.0 or newer, so it requires the least resources and can play reasonably well on a 603e or better CPU.

Version 1.1.6 plays very nicely on my G3 iMac (Mac OS 9.2.1)
