From the Guardian:
A huge mouth and no anus – this could be our earliest known ancestor
Discovered in sedimentary rock in Xixiang County in the Shaanxi province of central China, the species has been dubbed Saccorhytus coronarious for its sack-like, globular body and large mouth
So, a big mouth a fat, sac-like body?
And full of shit, because of that no-anus thing.
Gee, sound like anyone you know?
