Mystery Fossil

Data: I live in Russia. Two years ago my friend presented me with a fossil sea shell. It was located at an elevation of about 2,000meters on a mountain in Central Asia.

I would like to know more about this fossil. I am also open to the idea of selling this fossil as well. Please direct all queries to Yury if you are interested in this fossil

Positive ID:



  • Your ribbed fossil is a member of bivalve family Trigoniidae. I don't have access to my literature on the family at present, but it has similarities to some Pacitrigonia and Iotrigonia... but it is not in those genera. It has a Cretaceous appearance.
    The other specimen could be almost any bivalve in order Veneroidea. Not enough characters are visible to give a diagnosis.
