    Are these real shell fossils?

    This matrix of shells is for sale and the description says it is a fossil. I would greatly appreciate any advice on whether or not this seems to be a genuine, fossil, or a more modern matrix. Thank you so much for your expertise everyone.
  2. Location: Abbey Woods, London, UK Epoch: late Palaeocene to early Eocene (54.5Ma) Geology: Lesnes Shell bed of Blackheath Member Date visited: 4 March 2024 As the visit to Tankerton proved a bust, I was eager to actually find some fossils and decided to try out Abbey Woods when the Monday dawned sunny and mild. Again, this was a new destination and I thought it best to scout it out before dragging the rest of my family along. I took public transport with a nice muddy backpack and hiking boots, so must’ve confused a fair number of people on the London tube. Thankfully, the new Elizabeth line terminates at Abbey Woods, so it was pretty easy to access. It’s a fair walk from the tube station to the park (.7mi) and there is very little on the high street (if you could even call it that), apart from a few corner shops to get a drink and a Greggs. You could seemingly take a bus to the park, but I didn’t see any during the time I was walking, so probably best to plan on a walk. The main entrance to the park is somewhat signposted, although you can’t really see it until you get close; it’s near the pedestrian overpass. The park itself is beautiful. I didn’t know what to expect, and was very pleasantly surprised. The ruins of the abbey are striking, and the trails are clearly signposted and lead up into a wilderness area that feels like you’re completely outside the city. There’s a café/information centre near the ruins with clean toilets and running water. The water will be KEY to this site. To reach the fenced-in fossil bed, you can either go up a gentle slope to the left of the main entrance or take a steep set of stairs from the café. I would recommend going with the steep stairs when hauling water, as it’s considerably closer to the café and, although steeper, a shorter distance to travel. I didn’t know how far away the water was, just that it existed on site, so didn’t bring the appropriate transportation gear; all I had was a collapsible bucket, so abandoned the idea of wet sieving on site. Instead, I put on my waterproof trousers and began to dig down into the dirt with my trowel. It is spring in the UK, so the dirt was wet. The recommendations online https://ukfossils.co.uk/2016/06/16/abbey-wood/ are to wait for a dry period, but who knows when that will be, so I went for it anyway. The dirt was easy to scoop and move about into my sieve. I found Group A dry sieving, and was quite pleased, as what I had seen online indicated that it would be very hard going indeed to find anything during this part of the process. That being said, I didn’t start finding anything until maybe 18 inches down, but then it was fairly regular for the remaining hour and a quarter that I was there. While sieving, I separated out the larger rocks and sticks and put the fine sieved dirt into a bag to carry home. You can remove 2k from the site; I wouldn’t have wanted to carry more than that in my backpack for over an hour on public transport anyway! Another group joined me about an hour into digging – a mum, her 7/8yo son and his friend. They had buckets, a plastic sieve, and plastic shovels and were getting quite frustrated. I gave them some pointers and ended up inviting them to share my hole that I had dug out so they could reach a deeper layer. The son became frustrated quickly and just played around, but his friend loved it once I started pulling out teeth (and gave one to him). He found a couple of bits that may have been teeth that I recommended he take home to wash, and right at the end the mum found a definite tooth – she was delighted! I was glad to help them enjoy the digging more and get some results; I expect the friend will be back with his family at some point. There is a definite technique to follow at Abbey Woods. I’m going again with my family and another two families (kids range in age from 4-6) in a couple of weeks and will bring the following: - metal digging implements (and plastic ones for the kids to play with) - waterproof trousers for kids definitely (and recommended for adults) and generally outdoor clothes - large buckets for wet sieving - milk jugs to carry the water up the hill - sieves (mine is 2.5mm, but I would recommend smaller as some of the teeth are teeny-tiny) - bags for taking home micromatrix post-sieve - spare bags for muddy clothes and tools - snacks and drinks and money/card? for the café There is a wonderful resource for identifying your finds: <http://www.trg.org/downloads/fossils of abbey wood.pdf> It is written simply for the general public/amateurs, has a clear key for the diagrams, and has high quality images. I used it to identify the majority of my finds - just a few questionable pieces remaining. See photos below. I hope this information has proved helpful to anyone reading! Maybe see you there next time. 1. Marsh Clam 2. Marsh creeper 3. Moon snail 4. Auger shell 5. Extinct clam 1 6. Clam sucker 7. Extinct clam 2 8. Freshwater snail 9. Ray/fish mouth parts? 10. Sand shark (Gluekmanotodus heinzelini) 11. Sand shark 12. Sand shark (Jaekelotodus robustus) 13. Sand shark (Palaeohypotodus rutoti) 14. larger Sand shark teeth 15. Fish teeth? 16. Trace fossils 17. Questionable pieces; the top tooth is another Jaekelotodus robustus I left out, I think. The bottom left looks to be a partially erupted tooth? And the bottom right is either from a mouth plate or a piece of bone - really small fragment and hard to tell. Please let me know any confirmations/corrections. Cheers!

    Found SWFL - looking for help w/ ID

    Hi! I’ve found a good amount of fossil shells and coral today. Some I’ve been able to search on this site an others for an ID. But there are a few I’m not sure of and also might not be shells or coral at all. I’ll list some pics below. Any help is appreciated!

    Bone ID

    Would like thoughts on this bone I found in Northern New Mexico, Colfax county, approximately 6,800 ft elevation. Area has lots of remnants of sea shells and marine life. It's concave on one end and convex on the other. I'm also including a photo some of the shell specimens that we're located in the same area. Im always out looking for fossils. I just enjoy exploring and searching for things from the past.Any help would be greatly appreciated.

    Rock found near Cooperstown NY

    Not sure what I have here. Any ideas?
  8. Hello, My name is Kris. I haves been collecting shells since I was a child now and I started collecting minerals and fossils in adulthood. I often visit the Florida Keys so a lot of what I collect comes from there. I mostly find coral and clams, but recently I noticed I had collected a fossil crab claw years ago thinking it was a piece of coral. I thought it would be a good idea to start getting a second opinion on what I find, so here I am. I also sometimes buy something and forget to label it (😅), so I may also post to try to identify things I forgot.

    Preservation of colour in fossil shells

    Hi all, Some time ago I found this shell in (what I believe to be) the French Upper Muschelkalk (Triassic). Now I'm not into shells myself, but to judge from the remains of operculum on the underside of it, the specimen concerns an oyster. Most strikingly, however, the shell has a pattern of darker-coloured lines that do not correspond to any three-dimensional/elevational differences on the shell surface - which is, in fact, entirely flat. I haven't seen this on a fossil shell before. Now when doing a Google search for my response on whether it would be possible for crustacean carapaces to retain traces of their original colour, I bumped into an article that described that molluscs may incorporate melanin in the calcite of their shells to create the colour patterns we see (e.g., here). This got me wondering: could the lines I'm seeing indeed be traces of the original melanin pigmentation of this shell? And, if so, how common is this phenomenon? Does anybody else have examples of such shells? I'd also be very happy if someone could furnish me with a genus or species name to go with my specimen. But here I'd like to primarily raise the topic of ancient colour reconstruction in shells.
  11. LookingForRocks

    Can anyone help ID these shells?

    The shells on the bottom are abundant here in Edmonton along the North Saskatchewan river, does anyone know what they might be? The top one is more of an open spiral, the only one of its kind I've found. Thanks in advance ps - the tape measure is in cm/mm

    Need help identifying fossil shells

    Hello, I found what appears to be well preserved casts of clams and sea snails and also a possible bone or coral fragment but I’m not sure what most of them are except for the sea snails which I think is Turritella sp. But I’m not sure exactly. I’m not sure exactly what formation it is either but I do know it’s most likely the Ripley formation, Providence sand formation, Clayton formation, or Nanafalia formations. So I was wondering if someone could help me identify what species these belonged to and maybe even what period there from, thanks in advance.

    A Cluster I'm Prepping.

    Hello again. I managed to split that massive rock with a Bi-Valve inside. Other than that, there was nothing else obvious in it, so I've turned my attention to this little cluster that I found in Charmouth, Dorset, England, last April. It was in cliff debris on the beach. I'm sorry I don't know enough about layers, but it's Jurassic. It comprises of Ammonites and other shell fossils. I would like to know the name of the curly shell and the flat base, which I thought was a clam type shell, but it doesn't have any ridges or grooves on it. Also once I've finished the prepping, what type of coating should I use for this? Previously I have used clear varnish, but I've heard this is a No-no. Cheers Jes.

    Barton Geological Beds fossil Invertebrates

    The shells shown below I excavated from the Barton Geological Beds from the Upper Eocene band. The one on the far left is a crasatellid, the shell to its right is a cockle, and the three shells on the far right are scaphopods, but beyond this I'm not sure what they are and guidance would be appreciated. Thanks in advance for any proposed IDs Othniel
  16. I have been to Westmoreland state park and found 4 shark teeth for the first time. So today, closer to home was Chippokes State Park. I was told it was good for shark teeth but I found NOTHING. No sea glass, good shells or teeth at all. I was on the beach (newbie my second trip hunting ever); and a woman came up to me and said she was searching for teeth but found nothing but whale bone. Showed me a piece and so I did get some of those... but I have NO CLUE if that's legit. I mean when I googled whale bone, they looked different. In addition, how do you know a whale bone piece from a shark, dolphin or whatever animal????? I'm going to attach two photos (one of the front and one of the back). ARE these whale bone pieces? Thanks in advance for any help!
  17. Hi! I found these cool shells on Emerald Isle Beach in North Carolina yesterday and was wondering if anyone could help identify them. 1) Orange shell - this one is a super cool shape and also has some rocks trapped inside which is pretty interesting! 2) Purple/white - is this coral or just a cool rock? 3) Brown shell - also another cool shape (although it’s probably just broken) and the layering/colors are super pretty Thanks!

    Fossilized Shells

    All of these were found in Southeast Florida. Likely from the Pleistocene Miami Limestone (West Bryozoan Facies). Thank you.
  19. Hello! Here’s an interesting rock I found in Connecticut. It was part of an area of landscape stones that had been brought in from elsewhere (I think it’s probably from somewhere in the state, though, given all the geological variety there). I see the impressions of shells and what I think are crinoid fragments. I’m wondering if anyone can provide a more specific ID on any of those or a guess as to the age of the rock? It’s about 5 and 1/2 inches or 14 and 1/2 centimeters long, to give a sense of scale. Thanks! Side 1 Side 2 Side 1 details Side 2 details

    Fossil Shell/ Internal Cast Identification

    Looking for help identifying any of these fossilized shells and internal casts. All found in southeast Florida, Broward/ Miami-Dade counties [Pleistocene Miami Limestone/Oolite]. Maybe a few found more westward in the Tamiami Formation [Pliocene/ Miocene Limestone] Thanks. Fossil Shells.pdf

    Shells from southern Colorado

    Found in Northeast Costilla County Colorado in the Sangre de Cristo Mountains at almost 10,000 feet elevation. From limited research I believe they may be brachiopods from late Paleozoic? There are shells and snail looking things. Found next to each other but not together in the same piece of rock rock. I was wondering what other kinds of fossils may be in this same area. Like fish or trilobites? Thanks

    Acquired a collection

    Yesterday I received a 30 pound box of various shell, marine fossils, and some other miscellaneous fossils and a few extant bits as well. I will post in the ID section some as not everything has a label. It is a large overwhelming amount to sort through so this will be a bit at a time kind of thread. Please let me know if anything of the id tags are using outdated names or incorrect, etc. First an overall picture the seller had of the lot. Some Brachiopods from Wutach Germany What appears to be clam steinkerns also from Wutach Germany second picture of hinge point if that is useful. A pair of Glycymeris Americana with matching valves from Virginia Sticking with the Virginia theme a pair of Crucibulum constrictum A crab burrow from another Virginia location. And last but not least for now is some Olivia carolinensis from North Carolina I will try to make additional posts every few days as I unpack and sort this collection out. Stay tuned folks.

    Going to Wonderland

    I know that I went hunting yesterday. My neck and back muscles are screaming at me. We go to places we have visited before... In this case, some sort of coral reef or shell bed that was laid down , most likely in the Pliocene. Steve, who worked in the Phosphate mines said that there were 3 layers of shell beds in Bone Valley mines where he worked. Land mammal remains between the shell layers. In some locations, the Peace River has brought those layers close to the surface. I call this location wonderland. When ever I go there ... I wonder.. I wonder what layer I am finding.. Pliocene ? Miocene, whatever the 1st layer is... I wonder what process created what I see.... I went back in TFF to find that I have not revisited this location in more than 2 years. Back to the yesterday, A Barnacle.... This is solid rock... or blended silica with sand , mud , shell ..I wonder if the Barnacle "shell" filled with sand or mud and the silica transformed the whole thing to rock, sand mud , everything.. and I always wonder about the process details... Shells..... ..I wonder if we can identify the shells because that might tells us if there were Pliocene or Miocene.... I wonder about the process details... This is not hard fossilized rock like the barnacle... This is like mud rock,, that would break or crumble pretty easily So the shells existed on the bottom of the ocean, the ocean receded, Peace River brings in fresh water, somehow it is making mud-rock (which is common in many forms)... the shell sticks to the mud rock, then the silicification comes along changing the shells ,not the mud-rock., and the whole thing gets worn down until I pick it up.... Shell # 1 2nd Shell ..The rock weighs 40-50 pounds... a heavy item on the trip back in my kayak..Is this whole bivalve there ? Was this one transformed to Silica.... I wonder ... I also find botryoidal chalcedony, some bigger... some smaller. I think this formed in a "cave" in a echinoid sand dollar... Finally for those who appreciate more traditional Florida fossils, I found some of these also. Really like this tooth, it exihibits serrations with feeding damage and those CUSPS !!!... I wonder if if cusps on Megs is only true of Pliocene Megs. I am sad to say that it looks like the chipped the root on recovery. I guess what it comes down to is I am a wondering kind of guy....Enjoy
