Abstract
Abstract Latex impressions of the cuticle of a compression fossil of the ?priapulidPalaeoscolex piscatorum, from the Lower Ordovician of Shropshire, demonstrate a complex ornamentation of sclerites similar to isolated material, e.g.Hadimopanellaand phosphatized arrays. Each ‘segment’ is defined by an intercalary zone and bears two rows of sub-circular plates with prominent nodes on the upper surface. The intercalary zone bears two narrow grooves and a series of platelets, similar to but smaller than the plates. The remainder of each segment is occupied by microplates.Palaeoscolex piscatorumis fairly similar to a number of other species, includingGamoscolex herodesandMilaculum elongatum. Present evidence suggests the palaeoscolecidans are priapulid worms (or near relatives). Their abundance, combined with records from Burgess Shale-like occurrences, suggest priapulids were a major component of many Lower Palaeozoic benthic communities.
