  2. I recently visited the New Walk Museum in Leicester, specifically to see their Ediacaran fossils from Charnwood. Firstly, the famous Charnia masoni type specimen. This was significant as it was one of the first fossils to be described from Precambrian rocks. They had several type specimens, including this Charniodiscus concentricus type specimen. Sorry, this photo came out quite badly, but on the left is the Cyclomedusa cliffi type specimen. This is the Pseudovendia charnwoodensis type specimen

    Ediacaran fossils from Saudi Arabia

    Hellooooo i traveled 2 and a half hours to a Ediacaran deposit of sandstone and mudstone(600 million years old) near Madinah in Saudi Arabia. I found what I think is wave ripples, is that true? I also found some sort of imprint fossil showing perfect bumps, I don’t think erosion can create a pattern like that since there weren’t any others like it that I saw. if this is a fossil it is definitely the oldest fossil I am ever going to find since it is Precambrian. thank you so much for your time and effort!!!

    Guizhou Ediacaran?

    Hello, I see these pieces being sold as apparent precambrian Ediacarans from Guizhou, China. My question is, how does one determine if these are even fossils and biological in origin as opposed to just some random smudge or geological oddity? Is anything known about these sorts of specimens? Thank you.

    Ediacaran Still Life

    Firstly, I am NOT an artist and will never claim to be one! I always have and will refer to my “art” as doodles. I draw these on my IPhone with my finger… that is by definition a doodle! Secondly, I recently realized that there is very little art for a vast majority of Ediacaran Biota. So, I want to eventually give them all their time to shine, even if it’s just doodles with some artistic liberties. This is just for fun after all. My first is Anfesta. I’m not 100% finished but I wanted to share anyways! Cheers!
  10. Hi everyone, This fossil has always bothered me because of the way it felt in terms of weight and the cleanliness of the cut (there looks to have been some stabilizer added from the side, which I guess helps the case for authenticity). I only have one other fossil - what appears to be what was a very commonly sold Nemiana simplex - from a nearby region with a similar geology, and I could very well be wrong because it is indeed quite similar, albeit lighter with a more uniform grain. Since they're both Ediacaran in age and commercially not rare per se, I've always wondered if this K
  11. I think it looks shockingly similar to charnia. Maybe a cephalopod, snail, or plant? What could it be?

    Adam's Cambrian

    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.
  16. 555 myo fossils reveal early Arkarua feeding habits An international team of researchers has shed light on the feeding mode of Pentaradial Arkarua, strange, alien-like creature. By Annemarie Gaskin, University of Adelaide. University of Adelaide Newsroom, cosmos, April 6, 2021 The open access paper is: Cracknell, K., García-Bellido, D.C., Gehling, J.G. et al.

  17. So I recently acquired this little Ediacaran fossil. The round convex blobs have been identified as Beltanelliformis/Nemiana, but I'm not so sure about the flat one in image 3. Is this just a flattened specimen of the same genus? Or is this something else (e.g. a holdfast? muscular structures?)? The small bump/dimple in the center, along with the circular(ish) rings are of interest. Location: Podolia, Ukraine
  18. Hello everyone, I came across this fossil on one of the auction sites - unfortunately the seller knows nothing about its age or even the country of origin. He sent me the following pictures, which however are not very sharp :(( Nevertheless, does it look like anything Ediacaran to you? The size is 17,5 x 12,5 x 2 cm. The guy says it's shale rock. What do you think? I will appreciate your comments :) Kasia

  21. Hello, I'd like to share my most recently acquired fossil, a Dickinsonia costata from the White Sea. It's estimated to be a little over 550 million years old and is considered among the first animal macrofossils. I think an old stromatolite may be the next fossil item on my wishlist. What is the oldest fossil in your collection? Share it here

  23. Hello together, I just got a fossil that I am not sure what to make of. The species ID I got is Nemiana/Beltanelliformis, which I have no reason to doubt so far. https://en.wikipedia.org/wiki/Beltanelliformis What has me wondering is the preservation. Most pieces the seller had to offer seem to be imprints or remnants of sediment glued together by biofilms as one would expect for the species, like in the third pic. Containing mica interestingly. The piece in question appears covered in a shiny black layer that reminds me very much of what I once found in a glass bottle of c
  24. Ediacaran body fossils are extremely rare in North Carolina. This specimen came from a well dated Ediacaran Site. The site produces Aspidellas, microbial mat, and trace fossils. The Cid fm is the unit exposed in this quarry. Some have argued that this is microbial mat that had been influenced by the movement of water. If you look closely there is at least two specimens and the structure doesn't appear to show the MISS type features. I have sent some photos off to paleontologists who specialize in Ediacaran fossils. I'm eagerly waiting to find out what they think. I have had at least one paleon
