  1. Hello everyone. I just found out about these forums and so trying my luck on a couple mystery pieces that I have. I'm really excited to participate on the forum as we have been hunting for a year and have been on both US coasts, Sharktooth Hill and have had some great finds along the way. Fossil (pictures of the black piece) - My Fiancée found this in Venice, FL a few weeks ago. It is clearly bone based on the side view. The "bottom" side is flat with a couple of "scratches in it". The other side is very clearly ridged with 6 protruding parallel ridges. This piece was broken off on

    Fish Spine Fossil? ( Missouri )

    Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I was cracking Phosphatic concretions and this baby popped out! I was excited and thought I should share and ask what it is! I believe it is a cartilaginous fish spine, but I have little knowledge in such topics. Ps Information on good glue to glue together the cracked piece is welcomed!

Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation I have collected a lot of concretions and here are a few of which I have no idea what they could be My possible hunch is that some of these could be Fossilized Cartilage? Was really interested in knowing what this one was

    Hey Folks. This little concretion opened up over the weekend. Thoughts?
  14. Scientists have found a treasure trove of Mississippian shark fossils in Mammoth cave, Kentucky. ARTICLE HERE. Quote: "Based on what was exposed in the cave wall, Hodnett said the find includes a lower jaw, skull cartilage and several teeth. Hodnett determined the shark belonged to a species called "Saivodus striatus" from the Late Mississippian period, about 330 to 340 million years ago. @Archie "More than 100 individual specimens have been discovered during the project. Hodnett said teeth and dorsal fins of other shark species are also exposed in th
  15. If there's one thing that really makes me gasp, it's cartilage. Especially a whole darn skeleton (a shark, sturgeon, paddlefish, anything with a skeleton composed largely of cartilage.....) I find cartilage to be so amazing because of how difficult it is to be preserved. Plus, I find anything fossilized with cartilage also maintains other minute details (sensory pores, skin pigment, really fine details.) this is is a thread for anybody who wants to share their cartilage! I just realized the irony here, my name is Bone guy.....Anywho here is my contributio
  16. Apologies since this is modern versus fossil. But was my first ever experience with ray cartilage and I am excited. The vertebrae were found in different locations as were the 2 snouts I found. I also came across a ray's carcass that was intact but beginning to deteriorate. It's snout was skin covered but appeared to be the same. The vertebrae also looked identical to the ones I found. It was humped up I guess because of the drying and shrinkage of the skeleton. It had claspers so it was a male. About a foot and a half body with a long tail. The tail had hooked denticles? all along the top dor
  17. Well I am shipping my most recent shark cartilage to the "American Museum of Natural History" today. They said it is most likely another partial skull and since this stuff is pretty rare they would like to have in their collection. Maybe this partial can be used with other material for a study for someone.
  18. I found this associated cartilage on one of my outings a couple years ago near Lake Brownwood here in central Texas. It is Pennsylvanian age like most of my stuff. I have been removing matrix and gluing together pieces off and on for over a year but I am about as far as I can go on this puzzle. I was just to late in finding this before the weather had scattered it and softened the edges. As far as ID I am supposing parts of skull or jaw. Still the second most cartilage I have ever found together or at least almost together.
  19. I have been finding a lot of inclusions in a batch of coprolites from the Smoky Hill Chalk that assumed were bits of cartilage. One of the newer specimens from that batch had a piece of the material in question on the surface; enabling me to view it from the side. They look like little teeth, so now I don't know what I have. I have one other specimen that has a couple of the little tooth-like structures intact (one that I posted a while back that has possible Ptychodus tooth fragments). Is this skin with denticles, cartilage, a skull part or some sort of tooth plate? As always, any help is gre
  20. Help with details and ID please - Went out with DPS to Brownwood, Texas this past weekend - Pennsylvanian - Missourian and Virgilian Stages. Had a great time - found my first 2 trilobites so I was doing the happy dance. Found a very small 1/2 inch piece of what I thought was coral because of the unusual pattern at Wilson's Clay Pit. Filed it with my corals for that day. The next day we hunted a road cut that seemed to be older material than Wilson's. Found three more larger chunks of this - 1 1/4 inches, 2 5/8 inches and 3 inches wide that had the same unusual pattern and some curvature
