Abstract
A new anomiid, here designated Eonomia timida gen. et sp. nov., is described from the Upper Bathonian and Oxfordian (Middle and Upper Jurassic) of England and Normandy. Its attachment to the substrate by pallial secretion, and the detailed structure of its ligamental area, distinguish it from later members of the family. Uncertainty about the taxonomic position of previously described pre-Cretaceous members of the family makes it a likely candidate for the earliest known anomiid.
