    Favosites, or another tabulate coral?

    Fossil is from the Silurian of Gotland, though I am not aware of the precise stratigraphic unit from which it originates. On a broad classification level I'm virtually certain it's a tabulate coral (as you can see tabulae on the third picture), but while my initial hunch was that it's Favosites sp. I'm getting less and less sure the more I look at it. I have another Favosites specimen that I'm 100% sure about, and when I compare it to that, it definitely seems like there's subtle differences - at the very least, we'd be talking about two different species. In the last pic I've posted a compari
  2. 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
  3. A month or so ago I've acquired what seems to be a fairly solid Eurypterus Tetragrammatus specimen for a pretty bargain price, but now I'm a bit curious as to the authenticity. I'm not very familiar with eurypterid forgeries, and the main thing really that's causing some suspicion in me is the prepwork - is this how prepwork marks can actually look like? There's also the fact that there's no multiple appendages, but that I can explain away by only partial preservation. Here's photos. I was too lazy to put a scale mark, but I think that it's not really relevant here. Hopefully I have not
  4. Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadc
  5. I've been looking through some fossils I found around two months ago on Prinz Tobey Beach in Chicago, Illinois, which has Silurian aged fossils, and I'm wondering if anyone could ID any of the specimens (primarily Crinoids) to a specific genera?

  14. Hello guys, Summer is nearing its end so I decided to go and hunt the Niagara Escarpment of Hamilton, Ontario. The exposures I checked out at a creek ranged from the Cataract Group (early Silurian with the Whirlpool formation at its base and it sharply cuts the Queenston formation) all the way to the Clinton Group. Here is a pic of the Manitoulin formation, which is a part of the Cataract Group and is above the Whirlpool sandstone/formation. Above the Manitoulin formation is the mostly shale dominated Cabot Head formation. The Manitoulin and Cabot Head formati
  15. Over the last month or so, I've managed to get out to a few places. Although I can't say I've made stellar finds, I made out okay. In order of geologic sequence, I'll start off with the Ordovician. I have a spot in the Cobourg/Lindsay Fm that is typically very high energy, and so complete trilobite specimens are scarce. A few Isotelus parts, a Pseudogygites latimarginatus pygidium, a Ceraurinus marginatus glabella, and what may turn out to be a complete Flexicalymene senaria prone (to be determined after prep).

    Waldron Crinoid and Brachiopod

    A while back I made a quick stop at a small exposure of the Waldron Shale (Silurian) in southern Indiana. I only picked up a couple of items but since I have not previously collected the Waldron, I wanted to confirm (or get the correct ID) on two small items. I'm hoping one of our Waldron experts such as @Herb, @Ken K, @crinus or @squalicorax or anyone else that has some Waldron knowledge can help me out. The first item is a small, nicely preserved brachiopod. Based on what I could find, I suspect it might be a Stegorhynchus but I wanted to confirm this and if anyone can add a s
  17. It's been a long while since I've posted on here. I haven't been able to collect much lately, but I recently went out to some new haunts and came back with some pretty intriguing stuff I'll hopefully get to follow up on later. I'll start off with an interesting discovery I've had recently. The outcrop exposes rocks stretching from the upper(?) Brallier Formation to the middle(?) Foreknobs Formation. Although I tried searching in the past for brittle star trace fossils, I was mostly unsuccessful in this regard, and over time my interest in it shifted to the much more fossiliferous

    Possible fin from unknown period

    Hey everyone, I have this fossil I found along a beach when I was a kid. Unfortunately, I have no knowledge as to where I found it, other than it was an Ontario provincial park. I suspect it's a fish fin from either the Silurian or Devonian, but I want to get the thoughts of someone who knows more on fauna of this time. Thanks! Ps. There's a little something on the side of the rock that may help with id, it's in the second pic. Looks to me like a part of a plant.

  20. I was fascinated by this eurypterid fragment from Ukraine because it has a rough symmetrical pattern on the dorsal surface of the cephalothorax. There is a midline structure with apparent tracts leading to the eyes and perhaps other structures (like downwards toward the abdomen). It doesn’t look like ventral appendages of the cephalothorax projecting dorsally. This has the appearance of some internal structure, fossilized with perhaps some part of the dorsal exoskeleton removed. While very unlikely, the tracts toward the eyes might lend some support an interpretation of a neural or

    This is far from a complete specimen, but it has most of the appendages, which is quite nice. From the Fiddlers Green Formation at Lang’s Quarry, given to me by a good friend.

  23. I've recently come to acquire a collection of various fossils from the Silurian of Gotland. One of the larger specimens is this: My thinking is that this is 100% either a particularly large rugose coral, or an orthocerid. Could use some help.

    Cephalopod Shell Color!

    Hello all! Recently I have been obsessed with cephalopods and realized there is a real lack of reconstructions of the color patterns on extinct nautiloids and ammonites! This led me to compile a list of known fossil color patterns on cephalopods. After a year of on and off research, I found about 90 species of cephalopods retaining official or undescribed, original patterning on their shells. These are the first 15 species on my list. The color markings are based both on descriptions and photographs of the fossil material. The shades of the markings are based on the fossils, bu

    Is this a keeper ?

    I couldn't quite bring myself to toss this out without checking. Is this something good ? I think it's from the Silurian Hardwood Mountain formation, but honestly I hadn't been treating it as very important.
