Dennis Richards Posted October 15, 2017 Share Posted October 15, 2017 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 Link to comment Share on other sites More sharing options...
Miocene_Mason Posted October 15, 2017 Share Posted October 15, 2017 Looks like a spiny brachiopod, I'm not great with the genuses though. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Dennis Richards Posted October 16, 2017 Author Share Posted October 16, 2017 I thought it must be a bivalve; symmetry is left & right along the hinge line. So oyster, clam, scallop-like Link to comment Share on other sites More sharing options...
abyssunder Posted October 16, 2017 Share Posted October 16, 2017 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?

abyssunder Posted October 16, 2017 Share Posted October 16, 2017 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. comparative specimen from here " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Dennis Richards Posted October 16, 2017 Author Share Posted October 16, 2017 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 Link to comment Share on other sites More sharing options...
