FossilDAWG Posted September 26, 2022 Share Posted September 26, 2022 I'm amazed at how many people have Ediacarian fossils in their collections. I don't have any, but that's probably because I rarely buy fossils. Don 1 Link to comment Share on other sites More sharing options...

I see pieces at big shows like Tucson or Denver but some of the online dealers have it too so I shouldn't be surprised. I didn't think I had any until I found a piece from Michigan in a box of mixed fossils received as a gift years ago. I need to get it photographed for this thread.

I'm pretty much restricted to buying Ediacarans as there is no way I'll ever manage to collect fossils of that age myself. Link to comment Share on other sites More sharing options...

Mochaccino Posted September 29, 2022 Share Posted September 29, 2022 (edited) For the Mississippian, a Pentremites girtyi blastoid with brachioles and a bit of stem from the Big Clifty Formation of Sulphur, Indiana, USA. Blastoids were a group of filter-feeding echinoderms like crinoids, and it is generally fairly rare for their fossils to preserve the delicate filtration appendages a.k.a. brachioles.

siteseer Posted September 29, 2022 Share Posted September 29, 2022 On 9/9/2022 at 11:03 AM, rocket said: middle Eocene, Messel Pit, Germany, a nice mammal, Kopidodon, size around 80 cm from snout to tail I didn't comment on this when I was first posted but this is one of the most unusual vertebrates I've seen in this thread. Kopidodon belongs to an extinct order, Pantolesta, of mammals that appeared in the Early Paleocene and survived into the Oligocene. It was a diverse group with some apparently living like otters, others more like rodents, while Kopidodon was more like a raccoon. Unfortunately, the group died out without leaving any descendants but it lasted longer than most other Paleocene groups. Most pantolestans are known mostly by just teeth and jaw sections, but the Messel site has provided complete skeletons like this one. Wow, great specimen. 1 Link to comment Share on other sites More sharing options...
