The Museum of New Mexico is preparing an exhibit with an eight-foot-long bug that left its tracks in the mud three hundred million years ago. 
The bug, called arthropleura, is related to millipedes and sowbugs--those little black guys that roll into a hard ball when you try to pick them up. 
Another nice find was a fossilized dinosaur with eggs inside. 
That proves that dinosaurs laid eggs and may have been the direct ancestors of birds. This week's Science magazine has the full story.
