Abstract
A shell-boring polychaete worm was found replaced by the min eral limonite-goethite; this fossil is probably a limonite-goethite pseudo morph after pyrite, suggesting that the soft-bodied worm was originally re placed by pyrite. External structures such as a prostomium, anterior tentacle like palps, peristomial cirri, parapodia, setae bundles of the parapodia, and dorsal cirri of the parapodia are pre served. This worm resembles living members of the family Spionidae in form and habit. This discovery extends the known range of this family (Cre taceous?, Miocene to Recent) back about 365 million years to the Devo nian period.This publication has 0 references indexed in Scilit:
