  1. 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!!!
  4. Three years ago, I went to Peggy’s Cove to look around by the lighthouse and enter the nice shops and houses. At some point, I went around looking at the beautiful rock formations created by the glaciers that once covered Nova Scotia during the Pleistocene. I went to one of the very few erratics in the town, and checked underneath to see if I could find anything. I remember there was a cluster of pebbles and stones that were mostly cylindrical, but there were some fragments and shales there as well, however I am not entirely sure if they are endemic to the Mahone Bay / Halifax area aside from

    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.
  6. This was found in glacial till. It contains sedimentary rock from Precambrian through the Ordovician. Size is about 2.5cm / 1inch would love to know if any one has seen something like this? Extra excited if I can get a positive ID! In previous posts I have noted the 3 leaf clover like head in other examples of this fossil. However they are not as clearly preserved. There is a chance this is broken and splitting in 2 or its 2 making babies. I normally see them as a foot ball shape with the club head and no extra "wings" that make it look like a sting ray.

    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!
  8. I was told this was a type of Protomedusas from Jin Jia . I’m not super well versed in Precambrian biota but I have not been able to find any info about this anywhere. I thought it was a crinoid attachment point at first but that also doesn’t look correct. Any help would be greatly appreciated. The slab is about 2 inches total.

    I want to define fossil

    The fossil was found near the Mukhavets River, Belarus, Brest. Length ~ 6-7cm (~ 2.5 inch) whole piece. If I registered here, I will be impudent: you can recommend a book (100 -200 pages), an introductory course in fossils.
  10. It is possible to be this a real cyclomedusa fossil?
  11. 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
  12. 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
  13. Hello again Fossil Forum, Last week I posted a few pictures of what I thought might be fossil wood that I found on my property in Southeastern PA (Montgomery County, just over the Philadelphia County line). It seemed that it was possible that my rocks were fossils, but also maybe not... One helpful user suggested that I might polish some of the ends (hopefully crossections) of a few pieces. So below and in the next few replies I will post some pictures of a few pieces, for the polished parts I used a cabbing machine. I live at the bottom of a relatively steep hill and these pieces wer

  16. Hi. I have heard of Precambrian stromatolites found in the Precambrian rocks of Ontario but I am curious, has there been any reports of Ediacaran or Mistaken Point- like fossils being found in the Canadian Shield of Ontario?

    Pre/Cambrian Collection

    I have always been quite fascinated with the early stages of development of life on Earth. My interest really picked up when I first discovered the Ediacaran biota, and who can blame me. Those creatures are so enigmatic and fascinating. I was able to pick up a few specimens, but quickly realized that my desire for fossils greatly outweighed the supply and cost of Ediacaran fossils, and I soon discovered the equally fascinating and enigmatic Lower Cambrian Chengjiang biota. I was, and still am, blown away at the quality of preservation of these soft bodied critters. A lot of specimens come very
  18. Sinopaleus

    Grypania spiralis

    Generally accepted to be one of the earliest eukaryotes, these spiral ribbons are also the oldest macroscopic body fossils known to date. The Negaunee Fm. has been dated to 2.11 billion years old, but new studies suggest the unit is 1.87 billion years old. These ribbons are most simply referred to as a form of archaic alga, and existed when increasing oxygen levels caused global rusting of the oceans, also resulting in the extinction of other lifeforms unable to adapt to the then-toxic levels of oxygen.

  20. Good morning everybody, For anyone interested! Mid January 2019 I’ll publish a new book (in Italian, the english version is planned in 2020, but only if I'll recover the printing and translator costs) ‘Spiagge Cambriane. Meduse e tappeti algali’ [Cambrian shorelines - Jellyfish and Algal mats]. It concerns fossil jellyfish (and cnidarian in general) and their relation with algal mats, as a principal factor of the taphonomy of these soft-bodied organisms, covering fossils lagerstätten from Precambrian to the French Oligocene. The 232 pages book is rich of inedit illustrations coming from w
