A possible serpulid tube worm of the genus Filograna from the upper Permian Cadeby Formation of South Yorkshire, UK
Simple, tubular clusters from a single boundstone hand specimen, collected from loose material in the Permian (Lopingian) Cadeby Formation at Hazel Lane Quarry, Doncaster Metropolitan Borough, are tentatively identified as the serpulid worm, Filograna sp. A. The tubes are calcareous, found in vertical clusters, with some short sections growing horizontally, and with external diameters between 0.6 mm and 1 mm. Recent work on the Permian Tethyan deposits of Italy have identified occurrences of the genus Filograna from before the Permian-Triassic extinction, but the importance of this example is its provenance in the Zechstein English Shelf biota, where reported occurrences of Serpulidae have been rare.
