SFGate: Geologists Find Ancient Worm Feces

Swedish geologists have found fossilized feces from a worm that lived some 500 million years ago, media reports said Wednesday.

The tiny piles of feces were found embedded in rock-face near Malmo in southern Sweden by geologists Mats Eriksson and Fredrik Terfelt, newspaper Sydsvenskan reported.

Eriksson told the newspaper they examined the level of phosphorus of the samples and that "we realized pretty soon that it could not be anything other than coprolites, in other words fossilized dung."
