An ostracod-like arthropod with appendages preserved from the lower Ordovician of England

Authors


Abstract

A tiny arthropod with a thin, possibly poorly mineralized, bivalved carapace and a pair of annulated, uniramous, probable frontal appendages is described from lower Ordovician marine mudstones in boreholes from central England. It represents only the fifth Ordovician example of a conservation deposit with soft integument preserved. Its systematic position is unresolved, but it may belong to the Ostracoda; if so, it is a rare example of an ostracod with fossilized appendages.Arthropoda, Ostracoda, appendages, Tremadoc Series, Ordovician, England.
