  1. I'm currently working on a simulation of extinct biomes, i'm slowly learning how to make everything as realistic as possible for realtime 3d simulation. I would like to start with plants recreated from some Silurian, lower devonian and upper devonian, and slowly working to recreating the biomes in the areas where they lived and later i'l like to add animals aswell. All my research is made with google i'm not a professional in archeology or 3d art, some of the models are very simple and unpolished for now and will be updated. The project is in the early stages
  2. I had the opportunity to visit another Silurian site in the northern Georgia/southern Tennessee area. This is now the third such site I've visited, but the first in the Rockwood Formation as opposed to the Red Mountain Formation. As far as I can tell there's very little different between the two lithologically and paleontologically, with the Rockwood and Red Mountain occupying pretty much the same stratigraphic position. The difference seems to be that the TGS prefers to use the term "Rockwood" to describe it's Niagaran Silurian system and the GGS and AGS prefer the term "Red Mountain", mostly

    Local Railcut

    Went out to a railcut that slices through upper Racine formation. This locality is only 10 minutes from my house. I almost never visit it because of scarcity of fossils, however I was reading a paper that mentioned forams in chert and decided to take another look. Here you can see the beds dipping gently to the east. This is interreef strata. Closeby is/was a huge reef, now filled with garbage. Here is a chert nodule to be sliced up. Also, found a silicified coral and packed in my bag. Disturbed this guys slumber. Silicified Favosites

    Crinoid

    I’m looking for some information regarding this crinoid. It looks typical of the fossil crinoids I’ve seen from Morocco but I’d really appreciate a more learned perspective. A family member is thinking of acquiring this specimen. Only photo I have unfortunately. Thanks. @Tidgy's Dad
  7. Hi guys so today I came across a new shop that popped up in downtown Hamilton, Ontario. Anyway long story short I bought what appears to be Silurian coral fossil that originated somewhere on the Niagara Escarpment in Ontario or the State of New York. This fossil came from a peculiar museum that liquidated its collections in Niagara of Ontario and closed but the fossil didnt come with a label. Can anyone help me pin down what it is? I have never encountered a fossil like this on the Niagara Escarpment of Hamilton, Ontario. Also this was being sold along with o

    Silurian Fish Remains

    I wanted to start this thread on the identification and discussion of silurian fish remains. I have been learning a lot about this subject, and hope to share my own finds and discoveries with you. I also hope that this thread will not only include my finds, but finds of all members of the Fossil Forum who have such materials, so that we may share our knowledge on these amazing fish. Some of our members( @jdp, ... ) are quite knowledgable on such finds, and I am looking forward to working with you guys more. On each post, please include size, stratigraphi
  9. I have just found this microfossil. It is unfortunately incomplete, but the general shape is still discernible. I have two ideas for this specimen, a fish scale or an inarticulate brachiopod. Of these possibilities, I think that inarticulate brachiopod is more probable. The shape, "growth rings", and slight depression in the top lead me to this conclusion. On the other hand, its size, color, and the absence of such brachiopods from this formation, lead me towards fish scale. I am uncertain on both, and could use some help with this one. The specimen is the from the Leighton Formati

    Fish Coprolite?

    I have read in multiple papers that there are three theories to the preservation of thelodont scales. First, a rapid burial when the thelodonts have died under still circumstances, e. g., in a lagoon or other still body of water. This results in associated scales. Second, the thelodonts die and disintegrate in the open ocean, leaving behind disassociated scales. Third, the thelodonts were eaten, and deposited as coprolites. Now, I have just found an array of thelodont scales in a single small spot. The stone they are preserved in is a lighter color than the rest of the shale. The

    Tentaculite species identification

    I have found a few Tentaculites specimens from the Leighton Formation, Maine; which is Pridoli, Silurian. I was wondering if it is possible to ID them to species, based on the external molds alone. I have read in a few papers that many tentaculite species are identified by the number and shape of the rings on the shell exterior. Unfortunately, I have not been able to many definitive papers on USA Tentaculites sp, and their identification. The specimen below is only of the external mold. This is the best preserved, as well as smallest, of the specimens that I have collected.
  12. I have just finished preparing this little fossil. I really have not seen anything like it. It reminds me of a eurypterid head fragment, or something similar, but the ridges on the "internal mold" are perplexing. Also, it is horizontally symmetrical, suggesting a scale or segment. It is from the Leighton Formation, Maine; which is Pridoli, Silurian. The pictures below first show the "internal mold" under raking light, than of it under direct light. The third picture is of the "external mold" under direct light. It does not have any surface detail that would be brought out by rakin

    Unknown Leighton Formation Fossil

    When I first started prepping this one, only the tip of the bottom right corner was showing. I initially that that it was a trilobite free cheek, which is quite a common find for this formation. About half-way through, I realized that it was not what I had initially thought. Now that I see it fully prepped, I have absolutely no idea what it is. Approximately half of it had crumbled before I started preparing it, due to the soft siltstone it was preserved in. Any help would be greatly appreciated. The pictures are taken with direct light, as there are no small details on the surfac

    Gastropod ID

    So, I have been preparing this nice little gastropod. I have seen five other specimens that shared the same characteristics, but, unfortunately, some of them did not make it. Before I continued to prep this one, I was wondering if it is possible to roughly ID this gastropod. It would greatly facilitate prep work to have a good idea of its shape. All the specimens I have seen have had three whorls. The upper two whorl's ridges are almost absent, this has been consistent through all my specimens. The shape of the shell is coeloconoid. It was found in the Leighton Formati
  15. Hello everyone! I recently purchased two fossils, they were both sold to me as Ordovician the crinoid being from Wisconsin and the brachiopod from Illinois. @connorp has told me in a different thread that the dolomites of the region also preserve Silurian fossils and that these look much more like that. Doing a quick Google search I did find something that looks very similar to the crinoid I have, but I don't know enough about these animals or the area they come from to be certain of the ID. Here is the crinoid in question: To me this calyx looked quite similar t
  16. I purchased a couple of buckets of fossil/rocks from a friend who found them in the Ohio/Indiana area...which he told me was Ordovician and Silurian. Unfortunatly I've lost the paper that described where this section of fossil/rock came from. At first I thought it was a Crinoid...upon further inspection I noticed that there were patterns along with the ridges. So, I scribed it out of the rock. I noticed that one end was slightly larger than the other and that it was on the "Oval" side. There is a bit of pyritisation...especially inside the small end. So, I'm not really sure ...but I
  17. I found this piece by "popping" one of the "dishes" on a slab at Lang's Quarry in Ilion, NY several years ago. In this case, there is a bivalve-like fossil which was suggested to me was a cephalopod. Does anyone know the species of this fossil? I'd really like to learn more about it.

    Unknown fossil (myodocope ostracod?)

    I have been finding these small little fossils all through my specimens from the Leighton Formation, which is Pridoli. I suspect that they are myodocope ostracods, but I haven't found any ostracods that match it from my available literature. The specimen below appears to be an association of two valves. Each individual valve has a small protuberance in the middle, with two pits next to it; they are approximately 4 millimeters long, by 1.5 millimeters wide. The pictures below are first of photo with direct lighting, then a photo with raking light, to show the protuberances. Any hel
  19. A year ago I was able to hook up with my field comrade for some time in the Lagerstatte of the Silurian Eramosa in Ontario (northern section). This was a place where land and sea scorpions were found by the ROM. We did not find any. We obtained permission to enter quarries on account of connections and complying by safety rules. They do not let casual collectors in, so it was on account of those connections that we gained access. These quarries specialize in flagstone. Much of it is blank. Our focus was on the rubbly upper portion of the Silurian. As stated, fossils are ver

    Number 2 invert fossil

    This is another fossil that has me stumped. I think that there is a possibility of bryozoan, because of the pits, but I remain unconvinced. It is from the Leighton Formation, which is Pridoli. The pictures below are of the fossil under raking lighting, to show the pits, then of it under lighting from directly above, and finally with scale (mm). Thanks everyone!

    Silurian fragment

    Any ideas on this fragment from the Silurian Bisher Fm. Kentucky? Measures 1 cm.
  24. I had the opportunity to collect in the Red Mountain Formation recently, and considering the seeming lack of accessible sites in the area (RIP Tibb's Bridge) I thought it'd be good to show some of my finds here and say there is some stuff out there. At first I thought the site was in the Mississippian Lavender or Floyd Shales, which was my initial reason for venturing out to it as I didn't have the opportunity to collect in marine Mississippian units closer to home. I can say now with almost 100% certainty it's actually within the Red Mountain Formation, an early Silurian unit that is also a p

    Silurian or Devonian

    Hello guys! Please assist for dating of such rocks. I suspect it is Silurian, but it could be also later Devonian. I find plenty of these here like pieces of rocks.
