Ammonites from Guanling, Guizhou Province


-Andy-

Recommended Posts

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?

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!

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.

Someone on Facebook who seems to know his ammonites identified B as Neoprotrachyceras and C as Trachyceras sp.
