-Andy- Posted September 16, 2020 Share Posted September 16, 2020 Hi all, I recently obtained several lovely ammonites from the late Triassic (Carnian) Xiaowa Formation of Guanling, Guizhou Province However, I lack the expertise to identify them and I was hoping you could help I suspect A is a Trachyceras multituberculatum as this ammonite type is abundant there, and that species is also the most common ammonite there I can't tell what B and C are. I am not even sure if C is a different species from A. From my research, the following species are also present there: Trachyceras cf. aon Paratrachyceras cf. hofmanni Paratrachyceras douvillei Hauerites cf. himalayanus Protrachyceras sp. Arctosirenites canadensis Arctosirenites columbianus What do you think? 2 Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...

Runner64 Posted September 16, 2020 Share Posted September 16, 2020 I'm of no help when it comes to ammonites but those are some really cool looking pieces @-Andy-! Link to comment Share on other sites More sharing options...
FossilDAWG Posted September 16, 2020 Share Posted September 16, 2020 Perhaps @andreas or @old digger may be able to help. Those are quite nice ammonites. I think you are on the right track with the first one, but I do not know the differences between Trachyceras and Paratrachyceras off the top of my head.

-Andy- Posted September 18, 2020 Author Share Posted September 18, 2020 Someone on Facebook who seems to know his ammonites identified B as Neoprotrachyceras and C as Trachyceras sp.
