Hello everyone , I have been trying to identify this fossil for a while now, nobody seems to know. This is a fin spine from the upper cretaceous (campanian) of israel. Recovered from phosphorite rich marine deposits. It reminds me of hybodontiformes, but its different as it lacks their characteristic serrations, and by that time period they should have gone extinct in the ocean. Any help would be incredible!!

From the album: Catskill Formation PA fossils
My only Gyracanthus from Apr. 15. 2022 at Red Hill. -
Found this little thing a few years ago in a stream where Eocene Manasquan Formation is exposed (although I can't entirely rule out Kirkwood Fm). The four possibilities that I see are 1) ray tail spine barb, 2) fish fin spine, 3) crab claw pincer, or 4) jaw. This doesn't look like any of the ray barbs or crustacean pincers that I have collected so I am leaning towards 2 or 4. While the color/texture looks similar to the Eocene material from this site, it could be modern. What do y'all think?

From the album: Fin Spine Fossils
Currently unidentified, it comes from a rockpile aged to the pennsylvanian with a mixture of winterset and Iola limestone formations strewn throughout I found this away from any matrix and very delicate my best guess is that this comes from Ctenacanthus any other guesses are welcomed! its size is 11mm -
Hello! this is one of my weirdest things I have found at this location, I believe it might be a fragment from a fin spine? A piece from an Echinoid? Something else? I would love to know what it is and what species this came from! Some information on the area: Location: Missouri Time period: Pennsylvanian Formation: Most likely from a member of the Iola Limestone What makes this one of the most bizarre fossils I have found is the circular pattern on the fossil itself, as I have not seen anything like this in the area before.

This is a 12 cm long Hybodus fin spine from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). Its until now my best preserved fin spine from there. Some more pictures: -

Just a few bits that I received yesterday, some of which may be of interest to fans of Moroccan fossils. Firstly, a box full of the ubiquitous hybodontid shark fin spines (or 'spin fines', as I often call them during my less lucid moments). Common Kem Kem finds, but I do like them. The coin for scale in the middle is a shiny British fivepence, which is 18mm across, or 0.72/inch. Most of them need some prep, especially this beast, which may test my prep abilities, given how encrusted it is and how delicate these are. Seco

Hello! I found this chunk of something in Frankstown, MS while looking for shark teeth. There is so much petrified driftwood there and many pieces look similar to this. I picked this out at first thinking it was wood.. but I didn't see the little bumps along one side (I'm being very generic because I don't want to call it something it isn't and I'm not sure yet what it is ) until I got home. I also noticed when I got home that it is hollow and looks a bit like bone. After seeing this, I thought it was probably a fin spine or a ray barb. Others say it is a barb, but if it is, I'd love to know

Hello everyone, I'm a student in Milan and I'm currently struggling in trying to identify this fossil shark fin spine. Which taxon do you think it belongs to ? This speciment had been found in Northern Italy. The exact stratigraphic position is yet to be determined, but I can say for sure it's either Upper Rhaetian or Lower Hettangian. The spine is almost 11 inches long (28 cm, 29,2 cm if you count the missing tip) and is yet incomplete, for it lacks the basal structure and there's a big gap at 1/3 of its lenght (see images below). It also shows a pattern of denticles near the tip ( they
