blackmoth Posted January 13, 2021 Share Posted January 13, 2021 This is found in North China's Henan Province, mid Cambrian rocks, together with Bailiella. Obolus is much mentioned for this layer ( mostly very small, about 1mm) . This one is not only bigger, but also looks like a bit similar to some Paterina, to me. 1 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted January 13, 2021 Share Posted January 13, 2021 I agree, it looks more like Paterina to me, but I'm far from certain. It's very beautiful. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

It's very beautiful. what I gathered from some literature, it matches obolus ( in North China's mid Cambrian rocks) in that it is shiny with a luster of paint. and it is big (although the range of size given for obolus in these rocks is 3-8 mm, and this one is at least 9mm). I wonder if the paint luster thing applies to Paterina as well ( I guess it does as the the Paterina in the region was IDed as Obolus originally) , but the size range given is only " up to 3mm". There are numerous small shells (up to 2mm) which is hard to ID without a SEM. This one stands up with its sheer size. Link to comment Share on other sites More sharing options...
Misha Posted January 14, 2021 Share Posted January 14, 2021 That is an amazing brachiopod! Link to comment Share on other sites More sharing options...
blackmoth Posted January 19, 2021 Author Share Posted January 19, 2021 could it also be an Acrothela, which is also mentioned for similar layers in other areas? Link to comment Share on other sites More sharing options...
