  2. To all the shark expert of the forum. Is there any method or features to look for in order to determine if a shark tooth comes from a juvenile or an adult. I know that in a species well documented or largely collected, it can be easily determined by the size of the tooth. However in the case of a not well- documented or isolated tooth, is there a feature that could hint for the development stage of the specimen? Thank you, David
  3. Repairing a broken meg tooth

    Thanks guys. Part of the motivation is that I was too cheap to buy a complete big megaladon
  4. That is an amazing specimen! If Dr.Richardson identified it as Prothelyphonus giganteous, why do you need an arachnid expert to ID it? Were other arachnid species described after Dr.Richardson worked on it? BTW I'm confused about the math. 3% of 9 arachnids is 0,27 specimens. Don
  5. By morphology, I think we can narrow this down to the cranidium and pygidium of a trilobite from the dalmanitidae family. They may or may not belong to the same individual. I'm not confident to drill down to specific genus or species though.

    Wow Tony, excellent job on the color matching! If you hadn't said you sculpted the missing half, I would have thought you just glued the two pieces of a broken tooth back together. Well done! Now I know who to bring all my broken teeth to.
  10. Today
  11. Not counting lits bits and piece, finally found my first trilobite. It goes to show that you can find fossils in unexpected places, too. I was waiting to meet a friend and was just kicking over rocks in a misc (man made) rubble heap on the edge of town. Then this fragile soft siltstone broke apart badly, right across this beauty. I have no idea what formation it's from, and since its a junk pile along an abandoned RR I can't say for sure that's even from the county (Hollidaysburg, Blair County, PA, USA). About all I can say is it failed the fizz test, and there is a lot of parallel coloration running perpindicular to the bedding plane. For the fossil, there is a mold and cast. and part of me sees parts of more than one animal. I'm all new to trilos though. I think the closeup is a trilo eye, and was struck by the repeating details along the.... eye ridge maybe? What ID features leap out at you? Any advice on removing more material? That flake with the eye in the closeup just looked like waste, and I pried it off with my fingernail only to be surprised! (You might say my eye popped)
  12. Fish Fossils Queensland

  13. Fish Fossils Queensland

    Hello all we found a selection of fish fossil bones in marine sediments in Richmond NW Queensland . They are all of Cretaceous age we found a few Jaws,Ribs and others . Would anyone be able to ID the species of fish . More pictures in comments Cheers
  14. Are these wood fossils?

    This was a piece I picked up from the site. I showed it to a museum staff who said it was fossilized wood but he admitted he isn't a specialist in wood fossils. What are your thoughts on this? @ynot You know a lot about fossil wood. May I have your thoughts on this piece?
  15. Hi JP, That's a great find. I don't think I've seen one that complete before. The molars are more massive so they are more likely to be found at least near-complete but I've heard that they are usually found in pieces. Seeing this thread reminds me that I haven't been to Wyoming in at least twenty years. There was a time when I had the chance to walk the badlands in Park County but I got food poisoning the night before. I just didn't have the strength to climb and wander hills that day. Major bummer. Father Jenkins used to do side projects for paleontologists. He showed me a big box of Sharps Formation matrix (Early Miocene) from South Dakota and he was screening it in search of rare insectivore teeth for a researcher. I think it was J.R. McDonald. Jess
  16. Thanks a lot! She definitely is! Merci Coco! Thanks a lot, really appreciate it! Thank you Tony!
  17. An Eocene summer

    Hi JP, If you can get a shot of your Hyrachyus jaw straight down at the biting surfaces of the teeth, Fossillarry can identify it. Hyrachyus has been called an early rhino or at least a close relative of early rhinos, or more technically "a basal rhinocerotoid." I don't know what the consensus is now. I think Fossillarry would agree with you. Jess @fossillarry

    Nice job Tony, it looks great.
  19. Multiple Hunts this week

    Great post thank you. I could see the hemi also. What a nice tooth. cheers Bobby
  20. An Eocene summer

    Wonderful. It would be such fun hunting in those locations. Such a variety of vertebrate life. Thanks for sharing the adventures, photos and finds.
  21. My trilobite of the week.

    I skipped #69 in my sequence of trilobites so this week's trilobite is #69. Some trilobites get to be preserved in a light cafe au lait color in near white limestone, like the Acanthopyge and Cyphaspides from Black Cat Mountain. But many, like this one, are stuck with dark gray shell on medium gray rock. Life isn't fair, and neither is death. This is an Early Ordovician Pliomerid trilobite from the Filmore Formation in Utah, Lemureops lemurei.
  22. Crab fossils from Rakhine State of Myanmar

    I can't tell. They look old but I am not good at identifying between modern and fossil bryozoans
  23. Fall Break Fossil Trips

    Made a second trip to hunt the Maquoketa two weeks ago. Didn’t stay long due to the high water and piles of leaves. This was a nice find for me. A nearly complete Isotelus hypostome.
