  1. Past hour
  2. Unusual Tiger Shark Tooth

    Paleoc, I have been researching mayumbensis for the past couple of days though I am on the road and away from my references at home. I have not been able to confirm that it occurs in the late Miocene. It is known from the Peace River and the phosphate mines in Florida but only from the lower part of the Bone Valley Formation according to a longtime collector of the Bone Valley. He has also seen it from the Gainesville creeks (also noted by several members here with photos) which yield mostly Middle Miocene marine vertebrates and some younger land mammals. If you have a reference listing a late Miocene site or have collected one, I'd like to hear about it. Jess
  3. Hello! Unfortunately I do not have any Chama calcarata (punctata) or Chama lamellosa but I do have some Chama lamellifera from the Micoene of Victoria, Australia if you are interested?? Thanks, Dan
  4. Are these Galeocerdo Mayumbensis?

    My friend has a tooth that might be a symphyseal or at least the position next to it. I'll see if he'll let me get and post a photo. I edited my previous post to include a comment that the distal cutting edge of the cusp is shorter in G. mayumbensis than in cuvier. It leaves the cusp looking more broad-based with the effect of adding more surface area to the labial and lingual faces because of the higher cusp angle. I haven't seen what a lateral to posterior position would look like. My friend has a few specimens from the Peace River. A couple of them are mayumbensis but a couple of others (laterals) look like cuvier. Unfortunately, you can get both mayumbensis and cuvier there because the lower and upper Bone Valley layers are exposed by the river. I would think the cusp angle would decrease toward the commissure and the overall width would increase to the point that the tooth would look like a cuvier. Jess
  5. Fossil of alien tooling?

    +1 for the cast of a a crinoid stem.
  6. Fossil of alien tooling?

    My first thought is also crinoid, too big for blastoid I think (but I am not an expert)
  7. May 2019 - Finds of the Month Entries

    Wow... that’s outstanding!
  8. May 2019 - Finds of the Month Entries

    This is the before picture, still attached to the host rock. A small part could not be found so Markus flipped it and did a ventral prep on it. Lucky thing too, otherwise wouldn't have found the eggs!
  9. May 2019 - Finds of the Month Entries

    Edited original post now. Those are the eggs.

  11. May 2019 - Finds of the Month Entries

    Wow, what a beauty! I’m curious, what is the significance of the two circled parts?
  12. Potential dinosaur teeth (but probably not)

    The first is without question wood. The second is a bone shard, can't see it well enough to say mosasaur but its possible.
  13. I wonder if there is something better than resin to use: I don't imagine resin is in any way reversible, something fossil conservators value these days. I don't think Super Glue is easily reversible either but maybe it doesn't react with those minerals like resin does? I don't know about bringing out the colors either, but for consolidation purposes at least, it's usually Paraloid/Acryloid (for reversibility) or Super Glue/Crazy Glue that are recommended. But only if it's needed.
  14. May 2019 - Finds of the Month Entries

    Date found: September 5, 2018 Date prep completed May 17, 2019 Name: Triarthrus eatoni Geologic age: Ordovician Locality: Beecher's beds, Walcott quarry, near Rome, NY Quite a story behind this one. In the late 1800's Valiant discovered this quarry, later, Beecher started scientific study of it but Walcott (of later Burgess Shale fame) started to dig only a few feet away. For more detail click here. Fast forward 120 or so years. I got an invite to a paid day digging in this quarry with one of my fossling buddies, Gary V. Markus was a great host and taught us so much about trilobites and how to see them with his x-Ray vision. Gary found a complete bug within the first 5 minutes. I took 3 hours to find my first one. By the end of the day I had managed to find five. Markus' son prepped these for me and I just picked them up yesterday on my way home from the Penn Dixie dig. Two of the five had eggs and one had a 3 part terminal claw (foot?). Wish I could post more than 4 pics here. The circled parts are trilobite eggs. Needless to say there is soft tissue preservation of the legs and antenna as well.
  15. Fossil of alien tooling?

    I agree, reminds me of some silurian stems.
  16. Fossil of alien tooling?

    TFF doesn't do appraisals. Once you know the ID of what you have you could search the internet to see what others value it at. I originally thought this looked man-made because the spacing and regularity of the frills are a little too perfect. Looking from the side, the hole looks like it is a perfect circle. Maybe someone else could give you a more definite ID. I don't know a ton about crinoids. It could be a crinoid column print. Good luck.
  17. Help ID Please

    I don't but I have heard the suggestion that the big ones are likely made by crustaceans. i suppose you would have to find the remains of an owner that died inside to say for sure. I saw where that recently happened with the terrestrial corkscrew burrows but I haven't heard anything about marine identifications.
  18. Whale vertebrae?

    That 'ol boy has certainly seen some better days. Hopefully someone will be able to narrow down what it might go to given its size, but there is not much to go on.
  19. Whale vertebrae?

    @ynot I will post more photos I’m quickly learning about proper posting thank you for your help
  20. Mystery fossil with two members

    Keep looking and You will.
  21. Fossil of alien tooling?

    Is it worth anything?
  22. Whale vertebrae?

    It looks like a process off of a vert, but getting any further than that is guess work on such a fragment.
  23. Fossil of alien tooling?

    Another with tape measure
  24. Fossil of alien tooling?

    Still think it is the print left by a crinoid columnal.
  25. Mystery tooth

    Sure .. no worries ... it's such a fascinating area. So many great fossil hunting opportunities. If you are around Facebook ... The Palmetto Paleontological Society is a great place to meet locals. (Unless you have found it already) Though, I have yet to make it to a meeting. haha Bobby frequents the page and Ashby Gale is there to help with the vertebrate fossils too. The moderators are great. We haven't yet (?) been infiltrated by the crazies on the outside. And I'm assuming you've hit up the Mace Brown Museum of Natural History at the College of Charleston. Anyway .. welcome. Cheers, Brett
