Description. Slender segminate P 1 element with a terminal, reclined or recurved cusp that is usually broader than adjacent denticles, a shallow, posteriorly rounded basal cavity and three to seven anterior denticles.
Remarks. Despite their overall resemblance with Spathicuspus spathi these elements are either too long and bear too many denticles or their cusp is not broad and blunt enough to be assigned to that species. Some of them may not belong to Spathicuspus at all. Similar and apparently coeval elements were illustrated by Liang et al. (2016) and Chen et al. (2019) from other sections in China and Oman. Te element illustrated by Orchard (2005) has similar aspect ratio and denticulation as for instance the specimen we illustrated in Fig. 13O View Fig , but it is also much younger and may be only superficially similar.
Occurrence. South China: Luolou Formation, Spathian, Mingtang section, Nanpanjiang basin ( Liang et al., 2016), Upper Guandao section ( Orchard, 2005). Oman: Wadi Bani Khalid section, Spathian UAZ 7 ( Chen et al., 2019).
