The Neoproterozoic: revised

[ edidior ]

This painting by D. W. Miller, from the March-April, 1997 issue of American Scientist, shows how new fossil finds have revised our understanding of Ediacaran fauna.

The frilled, shell-less snail at the lower right is Kimberella, thought now to be one of the complex trace-makers of the late Neoproterozoic and a possible ancestor of the phylum Mollusca.
