Alcheringa 0, 000–000. ISSN 0311-5518.Sinoceras chinense (Foord) is one of the most important and dominant cephalopods in lower Upper Ordovician deposits of China and has been used traditionally as an index species for the lower Katian of South China. Eight published subspecies, including some morphologically diverse forms, have been assigned to the species, and a taxonomic revision of Sinoceras chinense is required. Based on an examination of the 33 published specimens and 12 new specimens, the relationships of Sinoceras chinense and its allies are analysed using cluster analysis and non-metric multi-dimensional scaling. The results segregate these specimens into three discrete groups: (1) the Sinoceras chinense (Foord) Group; (2) the Sinoceras eccentrica (Yu) Group; and (3) non-Sinoceras chinense Group. Accordingly, we e... |
