  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!

    Coral ID, please.

    I purchased this little rugose horn coral from a fossil, crystal and mineral dealer in Spain a few years back. The label is definitely wrong i at least that it should be Tryplasma loveni. I have T, loveni from the British Much Wenklock Limestome Formation and it looks rather different to this and I don't know of the species nbeing found in Morocco, The specimen doesn't look anything like any Ordovician coral I know, so may be Silurian. Most horn corals in Morocco are Devonian. But this does sort of look Silurian in the colour of its preservation, but that's not a great way to tell. It may not even be from Morocco, maybe Spanish, they sometimes say it's from Morocco as you are not supposed to collect, sell or export fossils in Spain, I think, so they sometimes change the country of origin. I have looked about a bit on the net but cannot find anything that matches, though I think I have seen the species before somewhere. Here are some better photos: Very pointed base: The top: Any guesses most welcome. Tarquin @TqB? Any ideas? Thank for looking everyone.
  3. I found this fossil in Alpena, Michigan, in the USA. It looks like a colonial rugose coral to me, but I’m not sure of the genus or species. It would have to be Devonian or Silurian, and native to Michigan. Does anybody know what this is? Also, is it a petrified or cast fossil? I attached four photos below.

  5. On Monday I went on a little trip to one of my top secret places to fossil hunt on the shores of Lake Michigan. It's a small beach in Northeastern Cook County, Illinois which I've always found lots of Silurian aged fossils. (1) This trip was no different!! https://silurian-reef.fieldmuseum.org/narrative/392 I found a large amount of small but pretty interesting Silurian fossils which demonstrate the diversity of reef supported aquatic life in the Chicago land area 444 to 419 million year ago during the Silurian era!

    Horn Coral?

    Hey everyone!! I sent pictures of my fossil, that I found on a Devon beach a few years back, to a museum in the UK to see if they could help me identify what it was! I personally thought it looked like a claw! And my sister thought a mussel! Turns out it was neither! I have attached the lovley little reply I received from the gentleman at the museum so you all can read too! It’s a Horn Coral! Which is a solitary coral, that became extinct many MANY years ago! Pre-Jurassic Period! I'm posting here in the hopes that anyone else might have any more information to add about this? I’m quite excited, and I’m ready to put it in a little frame somewhere so it can stay safe. Any and all input is appreciated! Thank you guys! Abby C FullSizeRender.MOV

    Colonial Rugose Coral?

    No known location as this is from a rock collection I acquired. Came across another bucket of what look like corals. Here is the largest in the bucket 10 1/2" × 6" × 7". If it is Id'd as a coral I will post the rest. I think they are 6 sided so maybe a Hexagonaria? Thank you for looking.
  8. Hi guys I decided to rescue and acquire a new unlabelled specimen. It appears to be a rugose solitary coral that can possibly come from the Devonian of south western Ontario. Can anyone give me any leads on the species level??
  9. Hi all, I visited Aust Cliff in South Gloucestershire, UK for a couple of hours last week. I wasn't expecting much as I know how heavily collected it is, but got a few bits of interest which I was happy with under the circumstances. I'd be interested in educated takes on a couple of bits of bone bed I found there at least, especially this first piece that contains what I believe to be multiple bone fragments as well as coprolite pieces and lots of small black fragments - not sure if scales, teeth or what. Here's a view showing what I imagine is one end of a reptile limb bone - could this be Pachystropheus? And on the other side are a couple of embedded chunks that have the honeycomb texture of bone but without the outer coating (not sure of the technical terms here!) No chance of identifying such things I presume, beyond 'yes it's bone'?

    Payson Arizona corals

    Some more fossils that I acquired from fellow members of the local rockhound club, a couple who spend their Winters down there (except this past Covid year). I've got the location info but not the accurate stratigraphic info nor IDs. These are from two different locations in the Payson area. According to the maps in Gem Trails of Arizona (which the couple used to find the sites), the horn corals are from a spot along a road on the way to 'Agate Mountain', and the colonial types are from Houston Mesa, "right at the top of the hill". I don't know if the two locations are the same formation, or...? (I guess they are all Naco Fm/Group(?) but more specific info is harder to find and I can see myself spending several more hours tracking it down.) Agate Mtn: Houston Mesa:

    Unknown Fossil?

    I found this in an area of North East China. The area has some volcanic history, and a lot of granite mines. I thought that I had it figured out, but am torn on what type of limestone it is, thus what era it could have formed during, thereby leaving me clueless about the small, potential fossil! Any help would be appreciated! Also, any clues on how the granite became fused to the limestone?
  12. Hi everyone! Yesterday my girlfriend & I went on a fossil hunting trip to an abandoned quarry in Resteigne in Belgium. https://www.paleontica.org/sites/fossil_site.php?plaats=10&language=en I am currently at home for some time due to mental health issues. I am currently dealing with despression and severe anxiety attacks all related to COVID-19, I am in a risk group and work in an essential store and the stress and way that people threat you finally became too much and I simply snapped. I finally decided to go see a doctor and a psychologist to help out of it all. Since besides going to work I hadn't left the house for the past 6 months and I really needed to get out to help me get rid of the stress and fear, so both the psychologist and doctor encouraged my to go on some fossilhunts as I needed to come out of the house and do some outdoor activities to help with my healing process. So yesterday I went on my first hunt to help me recover! The quarry we visited was an abandoned quarry in Resteigne and the rocks found there are Devonian in age. Most of the fossils found here are from the Eifelian (393.3 - 387.7 mya) and are part of the Jemelle formation. We arrived quite early at the quarry and spent almost 5 and a half hours searching for fossils here. Since we went on a normal week day, we were lucky enough the have the quarry all to our self! Since it was our first time in the quarry we didn't really find anything too spectacular, but I am very happy with the things we found and most important of all, we had a great and fun day! The surrounding environment was stunning and the weather was prefect, sunny but not too hot and not too cold! Ruguse coral in the rocks Only 15 minutes after we arrived we already found our first trilobite! Unfortunatly it was enbedded in a big boulder of very though rock at an impossible angle to remove. We did try to remove it, but when we noticed it would be near impossible and removing it would probably destroy the trilo we eventually decided to leave it. There where multiple other fossils in the same boulder, among them these nice Brachiopods
  13. Can please someone help me? I found this fossil from an middle ordovician place. Could it be a horncoral or a foram with a spiralform? The specimen is about 2 cm in diameter, some parts hidden in the stone. Any help very appreciated.

    A Quick Stop

    With all of the recent field trip reports being posted I have been that I haven't been able to get out there yet myself. The weather has been warmer than usual, but it’s also been rainy. Today I had very little time, but on my way home from giving my father-in-law a helping hand, I was able to make a quick stop at a local Mississippian site that is 5 minutes from my house. I believe it is St. Louis Limestone, but need to verify. I was only at the site for 20 minutes or so, but I picked up a handful of things. I didn’t get any pictures from the field as I was in a rush, but a few of the finds are below. I’ve known about this spot for a while, but it’s the first time I have stopped there. I think that’s because when I get a chance to go hunting I want to go to a place that it a little farther away since I have the extra time. I have been telling myself “It’s close. I can stop there any time...” I finally took the time, albeit a short amount, and I’m glad I did. The site is a low road cut. Well... it’s more of a water eroded slope on the side of the road than an actual cut. Little bed rock is exposed, except fragments mixed in with the soil from erosion. The dirt in the area is locally called red clay. With the recent rains, it was very muddy and the red clay tends to stain whatever it touches. You can see a reddish orange hue to the fossils. This was after a cleaning with water and a brush. I haven’t had a chance to try and ID these yet, so if anyone has any suggestions feel free to throw them out there! The area is littered with pieces of this rugose coral. This picture of a calice is a little more out of focus than I realized, but you get the idea... EDIT: Swapped the out of focus picture with one that is a little less fuzzy. This rock is full of these little gastropods. They are only about 1cm in height. I also found this gastropod and brachiopod. A close up of the gastropod. I like it. Hopefully this quick stop will hold me over until I can get out there for a long relaxing hunt.
  17. Can anyone confirm that this to be a tiny horn coral at the top of this little pebble? Its diameter is about 3mm. It's not at all perfectly preserved, but what a surprise I had when I discovered it through my clip-on phone microscope. Sorry about the grainy quality of the close-up image, it's as good as it gets using a $4.50 clip-on toy microscope Also, I assume those are beekite lined shell bits on the sides of the pebble? TIA!
  18. I am really trying to learn my common invertebrate fossils. Can someone, once again, confirm my tenative identification, or correct me? I really appreciate it. The fossil in question is this oval fossil. After doing some research my guess is it is a crinoid of some sort. I am guessing that the little "nipple" in the center of the oval is where the normal hole is, but why does it have a line disecting the oval into two distinct parts? If it is not a crinoid, can someone please tell me what I am looking at, and where I went wrong on my identification? Thanks, Doug
  19. Once again, I am studying and working on my own identifications. I am just needing someone to either confirm or correct me on this one. My first guess when I saw it was it was a gastropod of some sort, but after researching and looking at images online, my guess is that it is an internal cast of a hyolith. It was found in northwest Howell County, Missouri, USA. The fossil in question measures approximately 16mm and the host rock measures 80mm across. The widest point across of the cavity where the fossil in question lies is 8mm. Once again, I am truly appreciative of any help that you are willing to give me. Doug
  20. It has become a yearly tradition of mine to visit the upper part of Michigan's lower peninsula, around the Gaylord and Traverse Bay areas, for vacation with my family, and I often spend time looking for fossil in the area, mainly Hexagonaria/Petoskey stones, but for some reason they are far and few between. During my time in the area, I have also found a chunk of limestone containing what appears to be the glabella of a trilobite surrounded by what appears to be large, crystalized corals, possibly a Heliophyllum or similar rugose coral, a smaller piece of the same coral, and what seems to be the calyx and arms of a crinoid. Should I be looking anywhere in particular along the shores of Lake Michigan that aren't as well known as some of the popular tourist destinations? Also, are there any areas more inland that are accessible? (i.e. old quarries, roadcuts, etc.) Any and all advice would be greatly appreciated!
  21. 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.

    Around Salt Lake City in 3 Days

    So I’m still snowed in so here’s a trip from warm Early June. My friends and I wanted to hit all the closest rock locations around Salt Lake City and search for fossils and cool sedimentary geology (a couple of them being sedimentary geologists). We visited the Southern Oquirrh Mountains and a few canyons over on the east side of the valley at the base of the Wasatch Mountains. Here are the stratigraphy columns for both provided by Geolgic History of Utah by Lehi F. Hintze and Bart J. Kowallis. I did not lead this trip so I am not certain which rock layers the fossils were each from (I’ll point out the ones I do know) but I’ll say we went through the Cambrian and Mississippian in the Oquirrh Mountains and basically everywhere on the Salt Lake City column.
  23. Does anyone have any information on the roguse corals found at the Fern Glen formation? I can only find one but the ones I have found there look nothing like the one in the photos. Mine all look like the "normal" tornado shapes. The Fern Glen is Mississippian. Here is the photos I'm talking about Amplexus sp. http://www.lakeneosho.org/Miss48.html I just did a prep on one (maybe my best prep yet) it's just a common and not even a good specimen, but I tried some different techniques. I'll post it tomorrow after everything dries and sets in. It turned out better than I thought but I will welcome critiques.
