WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Pilina liaoningensis sp. nov. is described from the Late Cambrian Wanwankou Member of the Fengshan Formation, Benxi, Liaoning, China. Muscle scars and other internal structures are preserved very well in the para type; bifurcate bundle scars are described for the first time from the fossil Tergomya. This is the oldest known occurrence of pilina. Three species of Late Cambrian gastropods, "Maclurites" ulrichi (Kobayashi), Matherella walcotti Kobayashi and Lytospira wanwankouensis sp. nov. are also described from the Late Cambrian of northeastern China. Lytospira has been previously reported in the Lower Ordovician to the Middle Silurian of North America and Europe.
