Moontanman Posted February 20, 2011 Posted February 20, 2011 Oldest Fossils of Large Seaweeds, Possible Animals Tell Story About Oxygen in an Ancient Ocean These images are part and counterpart of a macroscopic Lantian fossil, probably a seaweed, with differentiated morphologies including a distinct root-like holdfast to secure the organism on sea bottom, a conical stem, and a crown of ribbon-like structures. Scale bar is 1 centimeter.

Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free waters. http://www.sciencedaily.com/releases/2011/02/110216132032.htm
