Hi

I recently obtained this specimen at a street market in Peru. Its 5cm x 4cm.

Looks scallop or oyster like.

Any ideas on id and age?

Regards

Dennis

Looks like a spiny brachiopod, I'm not great with the genuses though.

Happy hunting,

I thought it must be a bivalve; symmetry is left & right along the hinge line.  So oyster, clam, scallop-like

There are also spiny bivalves which might look like your specimen, for example Spondylus (the thorny oyster). (Look at the history)

 

Could you provide images from different angles?

The valves are still attached, but it could be a spondylid.

I would like to compare it with the specimen from Figure 2. The spines might be broken.

Sure, there is quite a resemblance isn't there to Spondylus calcifer? (without the spines).  And there is an important link to Peru/Ecuador where I bought this fossil.

Thanks for your investigation

Regards, Dennis
