Abstract

The first articulated ophiuroids to be recorded from Neogene deposits in the southern North Sea Basin are described as a new species, Ophiura paucilepis, based on two discs with portions of proximal arms preserved, plus an isolated arm fragment. The specimens were collected from the Oosterhout Formation (Pliocene, lower Zanclean to mid-Piacenzian, ca. 4.9–2.8 Ma) at sandpit ‘De Kuilen’ near Langenboom (province of Noord-Brabant, the Netherlands). A comparison with extant taxa from the North Sea and North Atlantic, such as O. albida, O. ophiura, O. sarsii and O. carnea, shows the fossil species to be characterised by a coarse disc scalation, which may be an ancestral state or a paedomorphic condition, similar to immature stages of extant taxa. The new species is compared to and distinguished from other records of mid-Cretaceous to Cenozoic taxa that have been assigned to the genus Ophiura either routinely, indiscriminately or with a query.
