  1. I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

    Possible bryozoa colony?

    I found this heavy triangular piece of what appears to be a bryozoa colony ,but at different angles and lighting I find it to show several other possibilities. This was retrieved from a receding river bed amongst many more corals and lingulla plates I also gathered. If anyone has an input or correction to my guess ,I greatly appreciate it.

    2023 Prep Jobs

    I haven't posted in quite a while, so I thought I would post pics of some of my 2023 prep jobs. I have done a lot more than these but these are the only ones I took a before pic. Zacanthoides idahoensis Cambrian Spence Shale Richmond, Utah Pseudogygites latimarginatus Ordovician Lindsay Formation Bowmanville, Ontario, Canada Ceraurus plattinensis Ordovician Bobcaygeon Fm. Brechin, Ontario, Canada Archimedes wortheni Mississippian Warsaw Fm. Fenton, Missouri Platycrinites bozemanensis Missisippian Lodgepole Fm.

    Devonian Identification Dilemma

    Recently I have taken interest in fossil hunting after discovering a plethora of fossils from some farmland in Southern Indiana. It is my understanding the fossils are from the Devonian period. My grandsons (5 and 6 years old) and I have collected several specimens I’ve the last couple of months. I have been searching the Internet for weeks trying to correctly identify our finds and just when I think I have something identified —I find other possibilities. I would like to make displays for the grandkids and label our other collections appropriately. I am in hopes this community would help identify the specimens, and provide advice on how best to label the fossils. I appreciate any assistance that can be provided. Thanks. —Bill Shingleton PS: All the fossils depicted are from Jeffersonville, IN.
  5. Can somebody help to ID this fossil? it comes from shallow marin miocene deposits is it a coral or a bryozoan?

    Adam's Early / Lower Devonian

    The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these groups are extinct or severely reduced in importance and brachiopods never quite recover. Also, the Devonian is the last time we see trilobites with such variation, large sizes and numbers and orthocerids too are much more uncommon after the rise of the goniatites. The massive tabulate coral reefs also disappear after the Devonian. Fascinating period and I hope to share some of its wonders with you. Equally, a lot of this is rather new to me, so I would be very grateful for any assistance, corrections or further information on my specimens. Thank you. The Early Devonian epoch is split into three stages, so let's start with the first of those, the Lochkovian, that began about 419 mya and finished roughly 411 mya. I have been sent a nice selection of brachiopods from the Kalkberg Formation, Helderberg Group by the Mighty @Misha, mostly. But the kind gentleperson also sent me this fascinating little bryozoan hash : It is dominated by fenestellids, which is usually the case in the Devonian, but other orders sill occur. These ones, I think, are Fenestella, but there are so many species in the formation that I wont take a guess as to species : Not sure what this one is ;

  10. Identification help requested! In presumable Burlington chert (Mississippian: Tournaisian/Osagean) of east-central Missouri (Lincoln County), USA, I recently came across a mostly moldic chert specimen of what must be a bryozoan, but I do not know what early Mississippian bryozoan would possess such a robust axis devoid of zoœcia, as in the later Mississippian Lyropora. At first I was not even sure it was the bryozoan’s own axis but instead thought the bryozoan was somehow associated with an orthoconic cephalopod. Each photo below is paired with its optical inversion to help visualize what originally filled the mold. Scales in mm. The main reason I feel confident that this whole structure is bryozoan is thanks to a colleague’s find of a presumably related unidentified bryozoan, also in moldic chert presumably from the Burlington Formation but from southwest Missouri, that shows the axis and its texture much more clearly than mine. Here is that specimen, again with inversions. Again I have no knowledge of an early Mississippian bryozoan built like this. (Yes, the axis surface texture looks quite a bit like the texture along the genal rim of some Mississippian trilobites! But it also resembles undoubted bryozoan textures I’ve seen.) Identification help requested! Thanks.

    Unknown bryozoan fossil from the Maastrichtian of Romontbos

    Hi all, Just through this out there, as I have no idea what to make of this other than that it contains bryozoa. Found at the Romontbos quarry in the Province de Liège, Belgium on September 24th, this fossil seems to comprise three superimposed layers, with the reddish bryozoan layer forming the bottom one, the smooth shell-like layer being on the outside and the gray layer of bryozoa laying in between. I found this piece on the depots, so exact stratigraphy is, unfortunately, unknown, although the composition of the marl suggests it comes from the Romontbos Horizon in the Chalk of Eben Emael. @ziggycardon @Mart1980 @Jasperfossils @Manticocerasman Here's a fun interpretation I have of it. But beware, once seen, it can't be unseen!
  12. This place is just like Wrens Nest Dudley i.e. Silurian. I like both places but find different things at each. Personally I have found more Trilobites bits at Wrens Nest. 1 - Arachnophyllum murchisoni Coral, top view 2 - Amphistrophia funiculata Brachiopod 3 - Favosites Coral 4 - Halysites Coral 5 - Heliolites Coral 6 - Kodonophyllum truncatum Solitary Coral 7 - Labechia conferta Stromatoporoid sponge 8 - Leptaena depressa Brachiopod 9 - Trepostome Bryozoa

    Some ordovician oddballs

    Hi folks, I made a long trip to several sites yesterday and brought home a couple of oddballs. First up, from St. Leon, I think this is Tetradium. I've found it before at this site and had it id'd here, but this appears pyritized and a bit different, maybe a bit larger segments? Thoughts? Second, from Lawrenceburg. I thought this was a giant gastropod wrapped in bryozoan when I first found it, but now I think it's just a very snail-like bryozoan growth. Can you see the spiral? Also from Lawrenceburg, is this oddity. The crater thing in the middle. Looks a lot like a crinoid calyx seen from the bottom, but I've never seen a calyx like this from either of these ordovician sites. Has a very bryozoan like texture around the top, but then gets smooth as it goes down. I suspect this is also a really odd bryozoan growth, but tell me what you think. Finally, there is this thing. I've been really wanting to find an Isotelus, so when I saw this, well, I said some choice words. Apologies for no scale, this was perched pretty high up in the Lawrenceburg cut. It's still there, as I convinced myself it had to be something else and it was on a big slab. It was around 6-8" long from top to bottom in the photo. I actually brought home a partial one of these before, but never ran it down to figure out what it is. It has a very defined edge along the right, that has a small "bead" on it, if you will. (Bead like in woodworking, if that helps.) Thanks!

    Waldron Shale Bryozoan

    Hello. I was looking at one of my old Waldron Shale hash plates and noticed a round piece seemingly connected to a Bryozoan colony and was wondering if it was the “stem” of the colony, for lack of a better word, or just a coincidentally similar piece on the bottom side of the plate. It also a smaller piece attached to the side that I assume is part of the same column but wanted to ensure it wasn’t an epibiont. Thank you!

    Some sort of Bryozoa?

    Found in the Mahantango formation of the Devonian. Ideas on genus of this specimen ?
  19. Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.

    Bryozoa?

    Hope everyone is doing well. Found this in the Needmore Formation so earlyish Devonian in age. My guess was some kind of bryozoan but looking at the texture up close I wasn’t sure. I’m not necessarily a bryozoan guy so I don’t have any frame of reference. If that is what it ends up being, does anyone know the genus/species? As always, I’m very grateful for your time.

    Horn coral or bryozoan colony?

    Found in landscaping gravel at a gas station on a 6.5 hour drive to Lake Huron for some fossil hunting. This is probably Devonian. Instinct tells me horn coral but it looks rougher than that and lacks visible septa at the top. Bryozoan colony? That’s my next best guess. Thanks! Love you guys.
  22. Hey there, me again (since my first ever post had great success)! The photos I am about to show you may depict one or two different animals, found in the Neuville Formation of the Trenton Group (Middle Ordovician). The host rock would be micritic limestone and all pictures were taken in Neuville, 30 km west of Quebec City (Québec Province, Canada). Stratas had a subhorizontal dip, slowly sinking into the Saint Lawrence River. Today, I have 6 pictures showing 6 different specimens. The photos might be showing the same animal, but seen from the top AND the bottom (which are quite different). In my opinion, those are probably encrusting bryozoans. The first three pictures would be the top of the animals, with the individual zooeciums (hundreds of small zooid holes) still preserved; whereas the last three ones would show the bottom. The thing is: I'm not sure and I never asked anyone knowledgeable. My second guess would imply two different animals. The three first pictures would show the top of encrusting bryozoans (or something else?), while the last three ones would be another animal (algae? stromatoliths? sponges?). I'm open to your feelings and diagnosis. Thank you very much!
  23. Day One; Locality Four Tizi N'Talghaumt Pass 19th February 2019 This pass runs through a slightly lower section of the eastern High Atlas along the course of the Ziz River which snakes its way right through to Algeria. These wonderful trees are common in the Sub Sahara, but I don't know what they are. We stopped by the altitude sign overlooking the Aoufous Oasis on the River Ziz. Whilst wifey and Abdulla admired the huge palmerie oasis, one of the largest in Morocco, Anouar and I nipped across the road to see what we could find :
