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.

Hello all, I recently ordered a big piece of Wheeler Shale and have had loads of fun splitting the rock and finding Trilobites. I've got a nice complete specimen of each of the common species (Kingii, Wheeleri, Interstricta) as well as a ton of molts, cephalons, and pygidiums. I am a new prepper and thought this would be a good way to start, though my dream is to eventually learn how to do Moroccan or Russian trilobites. I've been practicing on the molts and parts of the trilos, but the head I am prepping currently looks like it is pyritized. It's got a few pyrite pieces on it, but as I'm washing and brushing it off, the whole thing looks to have a golden sheen. I'm worried the water I've been putting on the specimens to soften the matrix will damage the fossil, though I've been scrubbing and brushing it off before it soaks in too much. Should I stop using the water as soon as possible or is it okay? And how do you more experienced preppers handle the pyrite? I love the look of the gold and don't want to damage it. For now I've been using these tools: Dental pick Thin Steel Wool Wire brush Kneaded Eraser Spray Bottle with Water I'm planning to get an air scribe soon to prep the complete trilos with.

Elrathia Kingii - Real, fake, or another species?
GreatHoatzin posted a topic in Is It Real? How to Recognize Fossil Fabrications
I purchased this a long time ago (I cannot remember where) and the seller claimed it was an Elrathia Kingii. As it says on the card, it is apparently “Pre-Cambrian,” although Elrathia kingii originated during the Cambrian. It appears at first glance genuine, but I’d like to be sure.- 5 replies

This was carefully prepped out with serendipitous results, as the main attraction was always the Asaphiscus. -

This bug was either thrown into an unnatural position during the burial process or is an uncommon example of enrollment in Cambrian trilobites! -

I had a bit of spare time today so I thought I'd prep a trilobite or two from my trip around the Confusion and House Ranges of Utah. (See trip report here) I had found this guy in someone else's throwaway pile probably after it came out chipped and subsequently scraped. I didn't think it was worth leaving out in the elements so I brought it home. Here's a before picture. After 4 hours of swapping between dental picks, wire brushes, toothpicks, and various Dremel attachments here is my final product. It's not perfect at all but I think it deserves to be admired for a time because it has not been on this earth for over 490 million years just to be chucked aside when it finally reached the surface. I even gave it a polish using a piece of newspaper. I don't think it came out too badly. The scrape is still visible on the thoracic segments but there's not much more I can do for that. What do you guys think?

I recently purchased a 40lb box of shale from U-Dig Fossils in Utah. Mid-Cambrian, Wheeler Shale Formation, House Range, Millard County, Utah. This morning after work, I split a smallish piece & one side had an odd dent, the other had an indistinct, slightly raised shape that sort of looked like a trilobite, so I started trying to find out if it was. This was the result. Using dental picks, a needle in a small pin vice, a # 428 Dremel wire brush (by hand) & another small, round nylon brush (Dremel) in another pic vice... and lots of patience. I think it's most of an Elrathia Kingii minus the cheeks (of course) measuring 1.5 cm in length. It isn't the cleanest & I have a bit more to do, but I wanted to "show it off" as it were. And see if I got the I.D right. Not the greatest quality pic, but I've also been up for almost 24 hours, so it may just be my imagination (pic quality or that I actually took a pic).
