What once appeared as a fossil of the primitive animal Dickinsonia turned out to be notihng more than a decaying beehive, shown falling off the rock on the right just a couple years later. (Gregory Retallack/Joe Meert)

The fossilized skull of Coccocephalus wildi, an early ray-finned fish that swam in an estuary 319 million years ago. The fish is facing to the right, with the jaws visible in the lower right portion of the fossil. The eye socket is the circular, bumpy feature above the jaws. This fish would have been 6 to 8 inches long, about the size of a bluegill. Photo credit: Jeremy Marble, University of Michigan News.
