Notidanodon Posted September 3, 2021 Share Posted September 3, 2021 Hi guys, these echinoids are from the miocene Murray river cliffs in Australia, they may be too partial to identify but It’s worth a shot 1 Link to comment Share on other sites More sharing options...
fifbrindacier Posted September 3, 2021 Share Posted September 3, 2021 (edited) Hi, i think they are temnopleuridae. My guess is Amblypneustes formosus but i'm not expert. To have a more certain and precise identification i call @caterpillar and @Coco .

Coco Posted September 3, 2021 Share Posted September 3, 2021 I’m not familiar with Australian sea urchins, but I suppose there are a number of possibilities. @caterpillar should know more than I do.

caterpillar Posted September 3, 2021 Share Posted September 3, 2021 Thanks for the call but I'm not Aussie Echinids specialist. But It could be Cryptechinus 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
