    Unknown fossil

    Fossil forum, I recently found an interesting fossil. I was thinking coral or bryozoan, but was unable to identify it correctly. It is from the Leighton Fm Maine (again), which is Silurian. Any help would be greatly appreciated. Here are some pictures of it:

    Help figuring out what this is

    I found this at the bottom of a dry river in the woods in Tennessee. Anybody have any idea what this could be?
  15. The brachiopod fauna of the Leighton Formation is so small that I don't often find one that needs some help with identification. This individual does. The closest brachiopod that has the same characteristics is Eoplectodonta (=Plectambonites) transversalis, but it only occurs in the Dennys Formation. The Dennys Fm has quite a different fauna from the Leighton, but it is the closest thing I could find. My other option was some sort of small spiriferid. I will have to defer to @Tidgy's Dad for this one. Below are two pictures of it, first of the cast, and second of the external mold
  16. Well, it has been a while since a post on the Silurian Leighton Fm. Had to make a trip due to family matters, and once I got back had a lot of work to do. I finally got into a position to start splitting and prepping more shale, and found this new little guy. I am torn between an operculum of a gastropod, and an inarticulate brachiopod. My main argument for an operculum is because of the shape - the only inarticulate brachiopods in this formation are Orbiculoidea and Pholidops. Unfortunately, I cannot find any reliable papers on the brachiopod Pholidops, it looks very similar but

    Coprolite?

    I have just found this little coprolite? yesterday. This is the second time a coprolite-like fossil has turned up in the shale from the Leighton Fm. I am not really sure on this one, though, due to the presence of crinoid stems. The fossil(s) are from the Leighton Formation, Maine; which is Pridoli, Silurian. The main reason I think it is a coprolite is because of its situation in the shale. The rest of the shale around it is relatively uniform, with no fossils whatsoever. The fossils present in it are one crinoid stem, quite a few ostracods, a very small Orbiculoidea brachiopod,

    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

    Rhynchotrema sp?

    I am unsure on the identification of this brachiopod. It is from the Leighton Formation, Maine; which is Silurian, Pridoli. According to Maine's Paleozoic Record (an excellent book that lists all the fauna and flora found in formations across Maine), there are only two Rhynchonellid genera in this formation, Camarotoechia and Rhynchotrema. It does not look like a Camarotoechia, but I cannot find many references for the internal mold of Rhynchotrema brachiopods. I would appreciate any references you have on this genus, as well as any advice on the identification of it (@Tidgy's Dad

    Am I wasting my time?

    I seen this boulder one day driving down my gravel road & threw my back out getting this bad dude in the truck by myself. Probably weighs a couple hundred pounds or more. It's approximately 2'x2'x2'. I seen the formations barely sticking up above the surface & curiosity got the best of me. I figured if it wasn't anything of interest or value I'd at least get some hands on training in prepping a fossil & the painstaking process involved with exposing it. So can anybody tell from the pics if there's any reason to keep etching away at this bad dude? Also what are these formations
  21. 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

    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

    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.
  25. 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
