PBS Eons has a new episode.  This one is about the Wormworld of the Ediacaran.

Elongated tubes, flat ribbons, and other “worm-like” body plans were so varied and abundant that a part of the Ediacaran is sometimes known as Wormworld. But in the end, the ancient Wormworld was ended by the actions of its very own worms.

Thanks to Franz Anthony (http://franzanth.com​) for the incredible illustrations of Ediacaran life!
