  1. Newbie needing an ID

    Hello everyone, I’m a newbie to fossil hunting. I found this yesterday, my first time out since taking up this hobby. I found it along a creek in Shawnee, Kansas, USA. Some of the rock in the area had clearly been trucked in and some was from the area so I don’t know how this particular fossil arrived at the location. The fossil is about 28 mm in diameter. There are clear pores that are on the outside surface. Where it is broken, you can see the pores extending inside the specimen. My first thought is a coral or some kind but I’m not sure what kind. Any ideas? If you need any information, let me know.
  2. Marine? and mammal? fossils from a collection

    I recently acquired a large collection of fossils and I need help identifying them. #1 This was found along Charmouth beach in the pebbles so I don't know the geological age. #2 These are from Petersfield from a stream. Again, no idea of the age of it. #3 and #4 I don't know where these were found but I'm pretty sure they belonged to some sort of mammal.
  3. Fossilized Whale Bone?

    HI. I'm a rock hunter and found some fossils along the way but it's not my expertise. This may be a rock but I'll let the Forum decide. This piece is about 1 1/4" long by 3/4" wide and is blackish with a rust color interior on the broken end. I found it on the Dunedin Causeway, Florida and it resembles whale bone that I've found in the Venice Beach area, but it doesn't have the ocean tumbled shape. What do you think??? Thanks again, BronzViking
  4. Corsicana Bouillabaisse

    Buried in my prep bin I found a marl nodule from the Corsicana Formation that I snagged for the gastropod/bivalve association. Longing for the days before the site was built over, I pulled this thing out for prep. Well surprise, surprise! Beneath the Neithea bexarensis and Gyrodes rotundus was a Dakoticancer australis carapace completely hidden. I’m lucky I didn’t run my scribe through it while reducing matrix. The movable finger from the right chela is poking out from under the Neithea, but I opted not to blow apart the other fossils exploring for appendages. Anyway, it’ll keep.
  5. nj cretaceous id fang or tooth?

    not sure what I have here......any help please,,,,thanks
  6. Growth, shade, competition

    It genuinely is my distinct pleasure to feature this pretty rare PDF and its few, but VERY nice images of overgrowth competition and sclerobiosis. Worth your time? You bet. About 1,2 MB harmecorabryozecolsciap-in-the-northern.pdf
  7. CALVERT MARINE MUSEUM DESIGNATED AS MARYLAND STATE PALEONTOLOGY CENTER http://www.calvertmarinemuseum.com/CivicAlerts.aspx?AID=278&ARC=418
  8. This fossil is from Guizhou, China. Any idea what is that?
  9. Jurassic Echinoids Dorset

    Can anyone help with a more specific id on these? The larger two are from Burton Bradstock and I assume the one on the left is a bivalve and the one on the right a sea urchin. The smaller piece in the middle is from Charmouth and another sea urchin. Both locations are jurassic and (obviously) marine.
  10. Coprolite

    This is from Charmouth, Dorset, UK. OK, its obviously a Belemnite in there but the texture of the matrix made me wonder if this is coprolite?
  11. Bone?

    This is from the beach at Charmouth, Dorset, UK. (Jurassic, marine, lots of ammonites, belemnites, etc) I may well have just picked up a stone but the shape is very bone like. Any comments welcome.
  12. All hail the snail/revisionary tactics

    the diehard cladist will like this anyway,but there's slightly more to this article than just that bacomurici279193.pdf less than 1 Mb
  13. Coral, Sponge or Bryozoan?

    I'm stumped. I've been collecting erratics off the beach along the Delaware Bay for the last six months and I keep coming up with mysteries. This specimen is 1" long. Unfortunately, because it is an erratic, all I can tell you is that rocks of this type wash down from the Appalachians all along the Delaware River and Bay til it reaches the Atlantic Ocean. They are Paleozoic, but I don't know enough of the geology from PA and NJ to narrow it down by rock type to a formation. Can't find a high enough resolution GEO Survey map, either. Other fossils in this type of rock are rugose corals, tabulate corals, bryozoa, and pinhead-sized crinoids, so big possible spread on the time frame. No trilobites yet, unfortunately! I have a small id sheet from the Mahantango Formation and an ID book for the Middle and Upper Devonian of NY, but neither have anything similar. I posted on the FB group and got three people saying it was one of these (yeah, I knew that) but each thought it was a different phylum. Can I get a consensus on phylum, if not a genus here? Can anyone give me links to good reference material for my other mysteries?
  14. Mio/Plio unknown

    There is a spot relatively close to me that is a late Miocene/ early Pliocene deposit. Consisting mainly of Great White teeth, marine mammal chunks, with occational (but rare) Meg. tooth pieces. Being a secondary deposit, everything in it got beat up and water worn pretty good. I was going through a box of bone pieces and grabbed this out for I'D. I was thinking inner ear bone? What are your views on this?
  15. Finally made it out to Purse State Park, now known as Nanjemoy Wildlife Management Area, yesterday. I had read that there was no beach to speak of at high tide, but wow! Low tide yesterday was at 11:15. We got there at 12:30 and there was already almost no beach! If only we'd gone when @RCW3D went two weeks ago! The air temp was a balmy 50 degrees, but the water temp, not so warm. Did that stop us? No. Did we get frostbite? Maybe. We weren't expecting to have to go wading when we left the house 3 hours earlier, so warm, waterproof shoes were not with us. We went barefoot on the chilly sand, wading occasionally, then warming our feet again. That way, we had warm, dry shoes and socks for the trip home. The only fossiliferous exposure we found, admittedly not going far north as we'd have had to wade waist-deep, was between the two trail openings. There is an exposure of the Aquia Formation that reaches about 10 feet above beach level there. The cliffs further north are much higher, but empty, so not a lot to look at along the walls. That's okay, most people don't go to Purse to look at the walls anyway. There were plenty of teeth to be found on the beach until our toes got numb. I dug a hole in the sand in front of the fossiliferous exposure and to my joy found some blocks of matrix buried there after they'd fallen from the cliffs. There was also a complete oyster hanging in mid-air from a fine tree root, three feet above the ground, that I managed to slide off without so much as nicking the root bark. Ha! As an added bonus, I got to enjoy the forsythias blooming on the beach! There are almost no fossil shells on the beach. They are so punky in the cliffs that they just disintegrate when they are exposed. However, I am optimistic that when my blocks dry out I'll have some nice specimens that I can eek out with some dental picks, paleobond, and patience. I also brought home a backpack full of micro matrix to sift. Never know what might be lurking in there!
  16. I live in Kitty Hawk, NC, and have the glorious Atlantic Ocean down the street. On a recent beach walk, I found what appears to be a fossilized bone from a large marine creature. I have looked through photos online and have not been able to identify it... and I am hoping someone might have a moment to satisfy my curiosity. It is approximately 9” wide and 6” tall... see photos below. I would be happy to take other shots if needed. Thanks very much!
  17. This is my final post for tonight, and then I will stop cluttering up the forum. Unfortunately, this specimen has been badly weathered and so may not be identifiable at all, but the shapes are so intriguing that I can't help but ask. Any thoughts here would be very much appreciated. The two angles are from different sides of the same rock. Sadly, I did not find this specimen myself, and so I do not have any particularly useful information on age or location. It was left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age. Here are the pictures. Thank you in advance for your time and input. Side #1: Side #2:
  18. nice Jurassic

    Found this (likely Callovian) beauty today in Cracow, but probably it comes from Zalas, Poland. Any ideas on the ID? I'm towards algae for the moment.
  19. Could use some help on these 0.5cm - 1cm invertebrate(?) conical spines in the well known Salem Limestone, a marine limestone of the American Midcontinent. They appear to be solid calcite but do not quite match up with the shapes of crinoid spines and echinoid spines that I know from the Mississippian. I have looked at umpteen Salem Limestone samples but have seen these spines at only one small locality. Any insights appreciated! but please provide your reasoning or evidence.
  20. Hello from a newbie in Central New York. I would appreciate it if anyone could identify the fossil in the attached photograph. I believe it is a tooth, but have not been able to find it on the internet. It has very complex, repeating stages in its structure. Thanks for any guidance on this! Norm
  21. Friday night Fossils

    I would really appreciate your help in identifying these fossils from eastern Virginia. I'm not familiar with the formations enough to give a name. I think number 6 may be a Pleistocene horse? I'm having trouble with photo sizing. I will try to add another pic of the other side in the comments. Cheers!
  22. Aust cliffs

    Ok so some weeks ago I visited a friend in Bristol one of the days he was in work I ventured up north via public transport (which is always good fun especially when the buses run only every hour and stop at 6) so was limited on time a found a few rocks containing some surface but fragile fish scales, having never been there before I really should have thought on to bring some field tools but was a more spare of the moment type of thing, anyway so back home with the blocks and have just started processing them (and by them I mean 1 so far very nervously) by using a bolster and chisel and splitting along the sediment layers, first I was wondering if anyone has any tips on extracting fossils from this type of matrix yes it is limestone however I remember reading somewhere that using an acid such as vinegar can also damage the specimens. However what I have been ding is using a manual tool to very little effect and the dremel, the problem with this is the manual tool just isn't really helping with matrix removal and the dremel isn't chipping the matrix as effectively as I would hope and instead more crushes than chips (yes this is a dremel engraving tool however this vibrates rather than using a pneumatic action) the other thing I have been doing is using a syringe and very weak solution of b-72 protecting any specimens and using small amounts of vinegar on the surrounding matrix however again the amount that seems to be removed by the vinegar is minimal its probably soaking in to the matrix to be honest but I don't want to fully emerge the blocks and damage precious fossils, I understand this has almost become and essay of writing and was wondering if I should post in the preparations forum however I do have a few pieces I was looking for some id help with again first real exposure to fossils that are non dinosaur in origin, and first time ever dealing with this type of matrix. Any help is always appreciated Matt
  23. small Australian cretaceous jaw

    Looking through the sieved material I noticed this little jaw ? I has come out of the marine material I get from Richmond in central Queensland in Australia. I refer to the layer it came out of as the fish mash layer as it is full of small fish material. In the layer I find fish, shark, turtle, Ichthyosaur, pliosaur, pterosaur and bird material. The fossil is 6 mm in length and quite fragile. Thanks in advance for any input Mike D'Arcy
  24. Maine trace

    Seemed like a good time to get this up. It was found in Little Brassua lake in north western Maine (low water, shallow lake). It is from glacial material that is most likely lower Devonian marine sediments.
  25. my sloth- Thalassocnus

    As my whale family is nearly complete now I went looking for other marine tetrapods. (and big fish by the way). I had for some time included Thalassocnus, the unbelievable swimming sloth of Miocene Peru in my to do list. Really fourlegged tetrapods are quite a lot of work compared with the highly reduced whales, so I was glad when I realized that the Megaterium made by geoworld was more or less my scale when seen as a big Thalassocnus of 3.3 meters. It finally arrived the day before yesterday, and today I spent some hours making it look more seagoing. I lengthened the snout, smoothed the skull and jaw. sawed out the intercostal spaces and made the limbones less bulky. The spinal processes are pointing more backwards now. (or at least their edges are) I am positively surprised how well this cheap model turned out after only few hours of work. Aloha J
