  1. Streetsville reconnaisance

    I hunted in Juan Emmanuel's old haunts. Went to Streetsville just for a reconnaisance. I didn't know the best places along the Credit River. So I went to a ball park between the river and Queen Street and just walked over to the water. The rocks scattered on the shore were just plastered with fossils...right where people picnic and entertain their children. Admittedly, most were of interest only to a beginner: Shell fragments, Bryozoan "wishbones", etc. Nonetheless, I had a good time and couldn't resist dragging some rocks home. Got a tetradium and a few nice corals, as well as other things to be identified.
  2. Hey TFF Members! It's been a while since I posted, and I see I have messages I need to reply to as well. I will get back to them ASAP. I have just been ridiculously busy and it's hard to keep up with everything. I just went up to Georgia to hunt for Agatized Coral Geodes! Cris got a saw and we were able to cut what we found in the video as well. I had a great time and we found some really great specimens that looked amazing cut up. Check it out when you get a chance!
  3. Favosites sp. from the Devonian Hungry Hollow member in Arkona, Canada. One of the more interesting corals I've collected, I'm trying to narrow down the species if possible. Any ideas?
  4. Hi guys! Haven't made any posts in a while but as I was going through some finds from Penn Dixie recently I have come across a few more fossils I would like to ID. The first few are what I believe to be Pelycopods but I have no further info on them. 1. Part and Counterpart 2. Part and Counterpart, found in the same piece of shale very close to number 1 3. Smaller one among some horn corals 4. A larger one, this one is thicker than the rest and is very different in texture. I have a few more pictures but I don't have space so I will include them below, Thank you guys for any help, Misha.
  5. Cretaceous ID

    North Sulphur River Texas Cretaceous find. Is this coral or a worn Globidens tooth? I'm leaning towards coral. Both are pretty rare finds at NSR so I'm not sure.
  6. This came from San Saba County, Texas; found in fluviatile terrace deposits (Qt). I would love to know more about this fossil. Thank you for your input.
  7. still learning

    Sorry I haven't been on the forum in a while since I've been working like crazy. After a 71 hour week last week I took a day off. My new job is a driving job around my local area so I make notes of places to revisit to rockhound ( I also do some while on layover time but its hard not to get dirty!). I went back to one today, It is a Bralier Shale (Devonian) exposure. Here's where I need some help. Are the tube things #3 corals or bryozoans? Any id's on the other things would be appreciated. Scale on all is centimeter.
  8. Coral Identification

    ADMIN NOTE: This was split out from the Fossil of the Month entry thread, as it strayed from the intent of that topic. It was decided that this might be useful as a learning tool. Thanks, Franz. Slow month so far but hopefully not everybody is out shopping for Halloween costumes and are instead taking advantage of the autumn temps to go out and add to their collections. Hoping to see the usual last minute addition of some enviable finds. Atlantic corals are something I know just a bit about (the extant ones anyway). A few years back the reef coral family Mussidae was analyzed using analysis which combined new DNA evidence along with the traditional morphological methods of classifying corals. Former students of a coral reef scientist friend of mine published an important paper resulting in the reclassification of several modern corals. ANN F. BUDD, HIRONOBU FUKAMI, NATHAN D. SMITH, NANCY KNOWLTON, Taxonomic classification of the reef coral family Mussidae (Cnidaria: Anthozoa: Scleractinia), Zoological Journal of the Linnean Society, Volume 166, Issue 3, November 2012, Pages 465–529, https://doi.org/10.1111/j.1096-3642.2012.00855.x The upshot of this as it applies to the genus Montastraea is that it now only contains Montastraea cavernosa, a species with large exerted "vocano-like" polyps which are roughly 5.5-7.5 mm in diameter and contain 36/48 septa. Here is a living Montastraea cavernosa colony: The other three extant species of Atlantic corals formerly in Montastraea were moved to the resurrected genus Orbicella (O. annularis, O. faveolata, and O. franksi). https://en.wikipedia.org/wiki/Orbicella These species (and the various hybrids or intergrates between them) have much smaller polyps (2.1-3.5 mm) with 24-26 septa. This genus is one of the primary reef building corals in deeper fore reefs. Here is an example of a living colony of Orbicella faveolata: I have no idea if taxonomic changes in the modern (extant) corals have any effect on what may be ancestral corals from the Miocene fossil record. I guess we would have to either know an invertebrate paleontologist (which I do) or find some papers online dealing with these Miocene (Badenian) corals that were published since the 2012 revision. If I can find further information, I'll post it here. Cool coral--whatever genus it belongs to currently. Cheers. -Ken
  9. Hello everyone, I recently found this piece along the shores of Lake Erie near Sunset Bay, NY. I'm not sure what I have here and was wondering if anyone might be able to help me identify it. For a little general information, the piece is pale white and features small tubular / stacking formations throughout it. When held in the light, the little stacks sparkle. The piece is just a little over an inch in diameter. Any assistance would be greatly appreciated. - Alex K.
  10. Devonian Coral - B.C. Rockies

    I picked up a few pieces of this stuff at a Devonian site in the Bull River Valley this past August. The tour guides weren't much help, and it's hard to find info about corals if you don't know the terminology very well and maybe there isn't much literature on corals from this site? If I could get the possibilities narrowed down, that would be better than nothing. I just figured it looked distinctive enough that someone might recognize it. Very small corallites, 1mm scale or less. All I know about the site is that it is supposed to be Devonian. Forgot scale on this first piece but the following ones have it. There is at least one other type (maybe two) on this piece as well, toward the right.
  11. Went down to downtown Dallas Trinity River and walked down the river banks. Right above the Austin Chalk layer I saw couple of interesting rock formations. I'm thinking these are ancient coral or geologic rock formations? I found these two rocks next to each other. They must been formed around same time. That round stone picture has round growth ring pattern on it.
  12. Fossil Coral?

    This is said to be a Triassic fossil coral from Guizhou, China. Any idea if it is a fossil coral and what species it probably is? Thanks.
  13. Petrified brain coral?

    I found this in my Seattle area yard, near the dead stump of a small maple. After washing and bleaching the septums appear filled with sand and shell bits. There is also something growing throughout it like a veinous system—likely plant? It is heavy. There are striated and mineralized layers. There is a ventricle feature and a faceted stem—it’s disturbingly brain-like. I feel honored to have finally guessed my way through your captcha (respect!)~~hoping someone can identify this oddity. Best guesses so far are coral or fungus, but I’ve not found any examples sporting this stem canal...
  14. Can anyone identify this object?

    This is the size of a 50 cent piece for those familiar with that coin. It measures about 2 inches in diameter - it's a bit oblong however. I can supply more photos if needed. Someone might identify this immediately with just the 2 photos. This was found recently along the Atlantic Coast shoreline along an outgoing tide after a storm. It's the shape of a top of a mushroom, even with the bottom having an a small indent in center. It's texture feels like pumice, and is light in weight like pumice. As you can see the tissue (or sheet) layers upon layers of holes that create this round small structure. Thank you.
  15. I put "brain" in quotes because I obviously know it isn't one, but helps describe its physical appearance. Although, maybe it is??? Lol. No idea what this might be. Found on my ranchland, western Colorado, amongst other dinosaur fossils on the surface. Appears to be agatized. It's in the shape that I found it and assume the entire piece would be a sphere. I was thinking some sort of coral, but due to the other dinosaur fossils in the immediate area, I'm wondering if it might be something dinosaur related. Pictures taken wet. Any guesses? Thanks
  16. Ocean Life

    Good morning, I was hoping that somebody could let me know if one of those is sponge and the other one is coral? Or if not could you please tell me what they are? Also, these were found in Glen Rose Texas, in the country at a creek bed . And that is Somervell County
  17. Marine Fossils (Ohio)

    Figured I’d post one more while I’ve got the collection out. When I was younger, my grandfather had a gravel driveway put in. I assume it came from Ohio, although I have no idea in truth. I frequently picked through it and found a few fossils. The gravel is clearly made of marine sediment for the most part - I’ve found brachiopods, trilobite fragments, shells, etc. I just wonder what these two could be? The first one has a couple of different structures in it - I’m thinking sponge or coral for the main part. The second, I have no idea. It looks footprint-ish, but this doesn’t make sense due to the marine nature of the gravel. Any ideas? Thanks, Nate
  18. Fossil coral ?

    Hello, first post here. Reside near Houston, Tx and found this in gravel bed on San Jacinto River near conroe, tx. From what I can gather I believe its fossilized coral. However, the only images I've been able to find online that closely resemble it have all been labeled as Indonesian fossil coral. Was hoping someone could help to identify it, and also shed some light on how common or uncommon it is to find this type of coral in this general area of southeast texas. Any help and info is much appreciated! And thanks for looking!
  19. Well I decided to stop again at the Garage Sale at an ESCONI members house. It had been a rainy night and before it opened at 10 am I along with another gentleman helped the owners daughter remove tarps that were covered with a lot of water. After that, I and a number of others began to look around for new items that had been placed outside since last week. I found a couple things that caught my eye, I don’t know if the prices are good for a couple things that I purchased , but it was to help the owner and I was willing to pay the price that I did. These trilobites appear to be from the Ordovician of New York, but I would not be surprised if they came from Canada, maybe @Kane can confirm. For these pieces I paid $130.00 I believe that they are Ceraurus and Isotelus. I got 3 Ceraurus- And then these Isotelus. I also got this box of Agatized Coral from Florida for $50, I have never owned a piece of this. To be continued-
  20. Fossil Tabulate

    I found this in rail road ballast, so I do not know original state. I believe more western USA. any ideas on possible location and other comments?

  22. September Hunt NY 2019

    September Hunt NY 2019 I cleaned our Devonian aged fossils from the other day and assembled a group photo of our favorite finds. The brachs are rare (Elythe, Meristina) and several rare and uncommon corals (Botryllopora, Heliophyllum delicatum, large Pleurodictyums) were found. The large orange Heliophyllum (4.5") is covered in epibionts. A large enrolled Eldredgeops found in a creek stone, needs more prepping and would have been over 3" long if prone. All finds were surface collected in NY. Thanks, Mikeymig
  23. Ancient Coral Ruins

    I dug up a Devonian Favosites coral recently with a group of corallites on the bottom of the colony that looked like tiny cliff dwellings
  24. Looking for a site

    Hi everyone, My name is Skylar Snowden. I am brand new to the forum and brand new to fossil hunting. I am not from Arizona and am relatively new to the area. I am a Marine Biologist/Curator by profession, and have recently started getting into fossil hunting. I have found a few at diamond point, but want to find some other options. I was going to try and head up to the Payson area again in a week or so, and wanted to see if anyone could elaborate on the site that is, I think, 87 near the E. Verde river. Or, any other sites in the Payson/rim area. I did try the Paleo Site, but found very little. Honestly, I really enjoy doing this, as it gets me and my 2 dogs out of the valley heat. Lol. Any and all help is greatly appreciated. Sky
  25. I found this tiny "pebble" lying at a beach north of Chicago when hunting for interesting non-fossil beach rocks and sea glass. (Yeah, there are people who collect and love sea glass and "just rocks" :-) So now, that I've started to collect coral fossils as well, mostly corals, I've been taking a closer look at some of my old finds and see all sorts of little fossil bits and pieces. This one when I found it, had caught my attention due to the tiny pattern, which I thought at the time was maybe something man-made. (Near a big city, there is a lot of man-made tumbled material to be found at the beaches). Looking at it with my magnifying glass, I saw that the individual white spots seem to have the same starlike pattern as the large corals I find. But this thing is almost microscopic. Is/was there really coral with such tiny corallites? If yes, what is its name? Maybe a tiny favositid? Top: Bottom (and side):
