A Boreal serpulid fauna from Volgian-Ryazanian (latest Jurassic-earliest Cretaceous) shelf sediments and hydrocarbon seeps from Svalbard

Description
Summary:Serpulid polychaete tubes are described from Volgian-Ryazanian sediments (?Pyrgopolon decorata (Stolley, 1912), ?Pyrgopolon aff. nodulosum (Lundgren, 1883)) and four contemporaneous hydrocarbon seep deposits (?Pyrgopolon aff. nodulosum, ?Pyrgopolon sp. A, Propomatoceros sp. A, Nogrobs aff. quadricarinata Münster in Goldfuss, 1831) from Spitsbergen, Svalbard. These are the oldest serpulid tubes yet described from fossil hydrocarbon seep deposits, and comprise the most diverse fossil seep serpulid fauna known to date. The genera Propomatoceros Ware, 1975 and Nogrobs de Montfort, 1808 have their first fossil occurrence elsewhere in the Early Jurassic and then appear in the Svalbard seeps much later. This is the first report of ?Pyrgopolon de Montfort, 1808 from a fossil seep site.
