A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

From the album: Wheeler Formation
This was carefully prepped out with serendipitous results, as the main attraction was always the Asaphiscus. -

There are actually four bugs on this decent sized plate! -
From the album: Wheeler Formation
This bug was either thrown into an unnatural position during the burial process or is an uncommon example of enrollment in Cambrian trilobites! -

Hey all, I bought this trilobite from a seller today and was wondering if anyone could help me ID it. I'm pretty sure its from Utah, and I think it's an Elrathia, but I just want to get some other thoughts or opinions. In the bottom left there seems to be part of an agnostid, but I could be wrong. The seller said that they didn't know where it came from unfortunately.

Hello again, still going back through my neglected trilobites. This one I had labeled in my mind as Elrathia+ Agnostid fragment. After learning a little more about trilobite ontogeny (https://www.trilobites.info/ontogeny.htm) I wonder if the partial agnostid may rather be a larva of Elrathia? Or can I rule that out by size? I hope the "adult" is sufficient for scale comparison. The more you learn the less you know. Best Regards, J

I now have 2 slabs with Agnostids: One that I found last week, and one that I bought years ago at Fernbank Museum of Natural History. You know what to do: Show 'em if ya got 'em! This is the hash slab I bought with some Agnostids and Elrathria: And this is the Barrandagnostus inexpectans that I found last week up in Chatsworth. Probably my most proud find in the Conasauga shale:
