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 both sides, so I don't know if it had more ridges as a complete piece. Any help would be greatly appreciated. Cartilage (pictures of the white piece) - (size of a nickel) This is not a fossil and my guess is part of a crab or something similar, but I've been unable to find a graphic to confirm it. It does have small ridges along the top of the "V" and it is not a symmetrical piece. My guess is this is something that many have seen before and someone will recognize it. Thank you in advance for the help and support. Derek and Sarah

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!

Multiple Phosphatic Nodules from Muncie Creek Shale that I could not Identify ( Missouri )
Samurai posted a topic in Fossil ID
Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale Specimen 1: Fish Coprolite? 1.8cm (nodule size) Specimen 2: Coprolite? 2cm (nodule size) Specimen 3: Fish Mandible? (2.6cm) Specimen 4: Coprolite or Maybe Braincase (I think it is very unlikely that it is) 2.8cm Nodule size 1.5cm (fossil size) Specimen 5: (2.9cm) Note: The placement of the fossilized material might be wrong as this was one of my first nodules and the fossilized material fell out. I recovered what I could. (Opened roughly 2 months ago) Specimen 6: Tessellated Cartilage with some Skin impressions ? (2.5cm) Specimine 7: Fish material? Thank you for reading and viewing this, I hope I can better understand these images so I can use them as references in the future!

From the album: Chondrichthyan Teeth From The Pennsylvanian Period
Specimen is 7mm in size. I was told this could be Hamiltonichthys after posting it to fossilId -
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

Treasure trove of Mississippian Sharks found in Mammoth Cave, Kentucky!
Fossildude19 posted a topic in Fossil News
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 the cave ceiling and walls. "We've just scratched the surface," Hodnett said. "But already it's showing that Mammoth Cave has a rich fossil shark record." Pictures from article:

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 contribution. A paddlefish named Protosephurus liui from the Early Cretaceous shale of the Yixian Formation (same place they found the Yutyrannus) in China. These fish are very cool, they do have a good amount of bones in their skeleton but there's also lots of cartilage. Hairs lined along the rostrum can sense the tiniest bit of underwater disturbance. You can see the skin is covered in tiny dimples which are sensory pores. Overall this animal is armed with a high tech radar system, perfect for hunting the smallest of invertebrates.

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 dorsal side curved toward the end. I was not as observant as I should have been to gather more details. I really wanted that tail! but I was unable to remove it and the body had a quite offensive smell. Also I did not have a camera so no pictures. Looking online the snout looks very much like an Atlantic guitarfish and its habitat is north Carolina and south US. Any help to confirm or point me in another direction would be greatly appreciated. Thanks

Cen Tex Shark stuff
thair posted a topic in Partners in Paleontology - Member Contributions to Science
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.

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.
