  1. Past hour
  2. Ray tooth?

    Rhinobatos with the root eroded off.
  3. Another interesting beach find

    Thanks. It was another first for me after many years looking.
  4. Fossil Fragment, Likely From Skull.

    I'm a complete novice here, so I'm probably way off base, but something about the way the lines kind of crimp together reminds me of some of the large turtle fragments I've seen, almost like a nuchal scute. It may not be shaped quite right for that, and I'm not sure how common turtle fossils are in your area. Just throwing my two cents in since there hasn't been much response yet.
  5. Ray tooth?

    Thanks, Brandy!
  6. Fossil ID please, U.K. Jurassic coast

    That does look like an ammonite in the pale rock, but even if you manage to prep it out it looks like part of it has been worn away. Top right looks like a nice pair of vertebrae, possibly ichthyosaur; nice find! Not sure about the other two
  7. Carboniferous Plant Hunt!

    Thank you! It was definitely a good hunt!
  8. Another interesting beach find

    Glad you got it ID'd. What a great find!
  9. The weirdest Fossil I have found so far (Missouri)

    Is there fossilized palmwood where you are? Especially the cross section and backside pictures you posted reminded me of some of the palmwood I've seen.
  10. Ray tooth?

    I don't know enough to answer your question, but there have been some good forum posts about ray denticles that might have some useful info.
  11. Kem Kem beds: fish experts needed

    I'm not sure about #1 being shark as almost all of the verts i've ever seen are not preserved with any processes, but I could totally be wrong about that observation. I agree with gar for #2, looks similar to what one may find in the Lance or Hell Creek formations. I wasn't sure if they had them in the kem kem but based on what others have said I'm confident in that ID. That articulated set of verts is sweet! If the others are right in that coelocanths don't have ossified verts, then it could potentially belong to a ray finned fish like aidachar or bawitius.
  12. Claw Core and Hoof Core?

    Happy Thanksgiving to everyone! I really appreciate this forum and the people willing to take the time and effort to answer everyone's questions and help people learn. I found these two fragments on the Brazos River in sandy gravel and low water near Brookshire, Texas. Mostly Pleistocene era here with some Cretaceous shells also I think. FRAGMENT ONE: CLAW CORE? The photos I'd seen of claw cores made me think this could be one, but since it's not very well defined, I've been wondering if it's even animal related at all. The most similar example I could find was a turtle claw core documented by @Harry Pristis , as seen here: Am I way off base? The flat smooth side and holes made me think it was vascular tissue, but I've wondered if it might be reef or even some type of mineral instead. FRAGMENT TWO: SMALL HOOF CORE? This looks like a very small hoof fragment with a rounded top and very flat bottom. The exterior looks worn on the toe-tip area and broken off toward the top. I had trouble finding anything that looked similar online. It does seem very small compared to several other hoof core examples I've seen. The closest thing I could find that looked a little similar was this camel hoof core fragment documented by @worthy 55 As usual, any help would be appreciated, and thanks to anyone who takes a look. --Brandy
  13. Fossil ID please, U.K. Jurassic coast

    Hello, please excuse my lack of knowledge in this area. This is the first time we’ve ever hunted for fossils and while we have collected a lot of lovely ones we can identify, these we’re not sure of. they were found at charmouth and seatown in the U.K. we’ve started trying to use an engraver on the stone, we’re guessing ammonite?
  14. Millard County surprise!

    Surprise trilobites are never a bad thing so, is this a good or bad "storied" book? Really want to get back down there and try and and some new trilobites to my collection. So something with more site info could be useful.
  15. Show me your six and seven gill shark teeth

    Thank you for replies Yes is perfectly true for Weltonia ancistrodon, but with W. burnhamenis is not so clear. For some position the main cusp is almost straight or slightly curved. In Heptranchias (lower teeth) most of lateral cusps have a regular size : https://www.semanticscholar.org/paper/A-study-of-the-sharks-and-rays-from-the-Lillebælt-(-Carlsen-Cuny/0d394a0f1306d1db48c4b54f29e8f6e4a7ad2a3c/figure/16 or very irregular as Paraheptranchias repens. For Weltonia lateral cusps have a regular dicreasing size, another link to illustrated my argue : http://www.sheppeyfossils.com/pages/weltonia_burnhamensis.htm
  16. Pennsylvanian in situ- Stoner Limestone

    I could use a fossil bench
  17. I am attempting some demineralization from this specimen as I write, however, due to its time above ground it is "bone dry" so to speak. In hindsight, I should have tried rehydration of a few samples too. I'll add that to the list. In the case of this specimen if any xylite was present, it has long since dessicated.
  18. I'll have to dig around a bit and see. I also have some small samples digesting (my wife was very happy I brought home chemicals and such to play with my rocks over the long holiday weekend here...) This stuff at a glance appears to very pourus in structure, I kind of wish I had some of the fibrous specimens to play with. I may have to see about purchasing some. I plan to do some sections for microscopy next week! Had to get a replacement cutter blade and the holiday delayed my plans. I am intrigued at the light absorption capabilities and am curious if it is a result of structure or chemistry. Blackest blacks are always fun. Plus, I am always looking for new possible substrates for the cell culturing I am working on.
  19. Today
  20. Trace cloven toe half?

    Would there be diagnostic morphology or measurement ratios that would support or refute the idea? Not in the business of proving, alas.
  21. Trace cloven toe half?

    Natural cast of a hoof core probably would be tough to rule out completely, but it would be far far tougher to prove conclusively I'm afraid.
  22. Carboniferous Plant Hunt!

    Thanks for the great and very informative report! Those are some nice and big plant finds too, I especially like the Cyclopteris and Annularia.
  23. Santa Fe river finds

    Thank you so much for sharing this album. Florida seems to have a lot of fossils in common with Texas, and your detailed photos have really helped me have a better idea of what some of my finds might be, as well as what to look for. The clear measurements are especially helpful. Thank you. --Brandy
  24. BONES

    This is such a fantastic reference guide and resource for someone like me who has just started finding Pleistocene fossils. It's really amazing that you've provided so much useful information for free here. Thank you so much for the time and effort you spent creating this and making it available. I've looked through several of your major albums now, and they not only help give me reference points for what I may have found, they also help me have a better idea of what to look for when I go out. Thank you very much. --Brandy
  25. Kane's Bug Preps

    An update on this as I come ever closer to being done with it. Much of the day has been focused on the occipital area, with a need to "channel" between the tubers and connect the deep furrow. This has to be done very slowly and carefully as it is effectively scribing a hollow beneath the tubers where there is a hard layer of chert that tends to shatter if you press just a wee bit too much. Careful sections and teasing smaller bits off is required. And even that is no foolproof method as sometimes matrix will break where it wants to break. To avoid catastrophe, I affixed two little strips of duct tape to the tubers. And thankfully I did. A small piece did break, but since the tape held it in place, I just gently lifted it with the broken piece, applied some cyanoacrylate, and the tape's presence allowed me to fit it precisely where it snapped. I swapped out the aluminum oxide for dolomite to focus on surface work. I then swapped that out for baking soda for finer touches. Do excuse the little bits of stubborn dust that I still need to blow out. This is how it looks dorsal side up, with that nice black plasticky shell. nothing quite compares to having it in hand, though. More detail work is needed, of course, but it will look very much like this in the end. The right lobe sadly does not continue. The left lobe upper continues just a wee bit more. Crush damage on the median lobe is on the posterior and anterior ends. There are trace fragments of the genal that would be incomplete and ventral, so I only indicated their presence. Fight valiantly as I did with the chert, I was discovering it would not likely get me much farther; given that the median glabella is smashed in on one side, a number of those tubercles are floating suspended over the base of the shell, so my decision was to remove the tubercles to have a "bald" glabella, or leave well enough alone. But the neat thing is, from this angle, you can see the tubers "flying" A closeup of the deep furrow-channel and how it connects to the deep groove between the lobes and the occipital. I spent a good chunk of the day focusing on these areas. The occipital portion is the lowest elevation on these piece, the difference from the top of the glabella to the furrow just shy of an inch. That's deep! Under the scope, it was like the Grand Canyon. Texture shot. What I've always enjoyed about preparing the glabellar furrows on these beasties is the appearance of these little clusters of mineralized gold stars/snowflakes. In the end, a real shame about it just being a fragment, and the bashed in part of the glabella. Extrapolating from the size of the components here, the original owner was certainly over a foot in length. So soon it is back to the box of parts to get on to the ongoing projects, and new ones.
  26. STH Bone/tooth/tusk?

  27. STH Bone/tooth/tusk?

    Hi everyone, I have what I thought was a mammal tooth until I cleaned the end off. From research online the end looks tusk like but I don't want to get over excited. Let me know what you think. Size is 1.8 inches
