  1. If one assumes that the Ediacaran lasted from 635 MYA until 538.8 MYA then I have a number of ediacaran fossils that have little to no identification. Any comments or suggestions from Forum members would be greatly appreciated. The first image is the front of an ediacaran fossil from Guizho, China. This specimen is constructed of a relatively fragile high sand content shale. Most notable is the spaghetti like fossil that could be compressed fronds, tubes or perhaps even some type of mold; I have seen nothing like it on the internet. The top of this image depicts a crescent moon shaped fossil and the portion of the lower left may or may not reflect abrasion. The second image is of the back of the Guizhou specimen depicted in image 1. The top of this image depicts another more detailed crescent moon shaped fossil illustrating fine "hairs" on the periphery. There are small less featured fossils in the lower portion of this image. It is possible that the crescent shaped fossils are among the petalonamae. Images 3, 4 and 5 are closeups of the fossils depicted in images 1 and 2. Image number 6 is of Nemiana simplex fossils from the ediacaran in Mulgilw, Ukraine. When I first acquired this specimen it was thought to be a jellyfish attached to the sediment. More recently it has been proposed that it is the result of algae. Any further information would be appreciated. Image 7 is of Prota-medusae fossils from 550 MYA that were found in Gadsden, Alabama. I was pleased to see that such soft bodied creatures were preserved in the fossil record. Comments, suggestions, and corrections are welcome.

    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.

  8. 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 As well as a discoid fossil. They also had a large cast of some other fossils of Charnwood, I think this is a more recent addition to their display. This is Auroralumina, a cnidarian and the current oldest known predator. Unfortunately there was no information about this, not even a sign to note it as Auroralumina. Bradgatia. A cast of Charnia masoni. And lastly another disc. Aside from Ediacaran fossils, they also have Mesozoic fossils from Leicestershire and Rutland, but I will save these for another time.

    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!
  16. 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 Kimberella was legit given a fluctuating price tag that has been quite high in the past but seems to have levelled out in the mid range. As someone who once taught a diversity of life course, I am an absolute sucker for fossil items that include key moments in history, as well as evolutionary transitions. I've included pictures of the Kimberella in question, as well as a couple of items I place it next to because I'm a giant nerd and I like to imagine that this is the footprint left by some sort of mono- or poly-placophoran ("chitons") 600 million years ago. I wish I had some "smell shelly fauna" or traces left by an Aplacophoran to illustrate the molluscan "root" but alas this is it for now. The orange fossil shell is of a monoplacophoran named Proplina grandis (Gasconade formation, Missouri, Lower Ordovician) - unconcerned about its provenance - and a modern chiton from the Philippines. I know for a fact this quite popular seller misidentified a fossil fish sold to me as a madagascan coelacanth very, very early in my building of a fossil collection; this is also a reason I'd like to know if the provenance is legitimate; I've been hesitant to deal with them since and passed on many fossils as a result I'd probably only look to add a sea pen-like fossil from the region - unlikely due to the hefty price tag and commercial rarity - but I'd like to learn more about what to look out for nonetheless. As always, thanks for any insights the community might be able to provide! Cheers Marcus p.s. And happy fathers day!
  17. I think it looks shockingly similar to charnia. Maybe a cephalopod, snail, or plant? What could it be?

  21. 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
  22. 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

  25. 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.
