Abstract

A peculiar nodule from the Upper Liassic (Toarcian) shales of Whitby, Yorkshire, is interpreted as an infilled burrow system which was probably excavated by a shrimp-like crustacean (possibly Glyphea sp.)- This interpretation is supported by comparisons with fossil crustacean burrows in the ichnogenus Thalassinoides. The nodule had formerly been regarded as a cluster of fossil embryos from the aquatic reptile Plesiosaurus.
