    Catfish Pectoral Fin Spine

    From the album: Neutache Shoreline

    VM7 3/10/24

    © CC BY-NC

  2. Found in glacial deposits E Kansas. Originally I (naively) thought this was a shark dorsal fin spine- after a few minutes of research I found I was mistaken So, I now (fairly confidently) am believing this is a fish pectoral fin spine. I'm no expert on fish material, but one guess of mine is this is some sort of Catfish spine... but I don't know what other fish have pectoral fin spines. Any thoughts? As always, thank you- I appreciate the help Side note: used Paraloid B-72 to painstakingly piece back together Here is a in-situ shot (river gravel bed):

    Permian I.d. Question.

    Hi! Awhile back i sorted through some Comanche county Oklahoma permian matrix. li’ve got a lot of pieces needing i.d. But I thought I’d start with this one. Its right at 5mm long in some ways I think it’s a tooth but I’m not sure. Anyone have any ideas? Today I was trying out a new magnifying device so I thought this was the perfect time to ask! Please ignore the date.i havent reset it yet…

    This was found on south Myrtle Beach a few days ago. It looks like part of a spine to me but I have no idea what species it may be from. Is there enough bone to make an identification?

    5ft spine articulated from what? SD

    Was wondering if this spine is from a plesiosaur or mosasaur. and is it a neck, tail or trunk spine? Found poorly preserved in Pierre shale sd. There are a few ribs there too. The reddish end pic is where I did a clean break form some more of the fossil which is in different jacket. I roughly cleaned this spine but don't think it's worth putting more time into with all the gypsum.
  7. Polybranchiaspidida

    What do you think its ID is? I need your help.

    It came from UK,Triassic period.But I don’t know its ID and formation.Please help me!

    Articulated shark spine?

    Found them lined up like this in Pierre shale sd. Never seen verts like this before but heard shark vert are flat like this. Any insight would be great!

    Tip of a ??

    Found a few of these. Tips from a Hadrosaurus? Colorado
  11. These photos are of what appears to be a large fossil found in my hometown in Hughes County, Oklahoma. I have not seen them in person, but I trust the person who posted the photos. The rock is large and initially looks like a spine, but I know that concretions can be misleading, too. I am going to reach out to him and try to find out if it was found near a current water source or not, if that helps. Thanks!

    Mosasaur spine

    Hello, I have found in a shop this "mosasaur spine" fossil. Is it a mosasaur? For what I see the vertebras are procoelous which is what you would expect, but I would like some expertise council on this. And moreover is it possible to identify the which type of vertebras are those? And to which mosasaur they belong? The full plate measures 55cm x 20cm and each vertebra measures 8-9cm more or less. It's from Thanks! Edit: It's from morocco.
  13. Found this articulated in SD Pierre shale and wondering what fish species it might be? Most isn't clean but i did rough clean on one. Thanks
  14. Good morning. I would like to buy a Spine of Spinosaurus Fossil. But I'm not sure that is real or not. Would any expert give me some advise, please? Thank you so much

    Southern Alberta Fossil Hunt

    Well, it's been a while since I last posted. Covid and aging have slowed & diminished my fossil hunting buddies. I grabbed one and we blasted south for 6 1/2 hours. Hadrosaur & Centrosaur bone pieces eroding out of the Bearpaw shale layer were our focus. We found many pieces in the water. I picked up a number of pieces that seemed to be related. After bringing them home, cleaning them up and scratching my head for a couple months, I finally pieced together 18 pieces. I was able to confirm with Dr. Caleb Brown from the Tyrrell Museum near Drumheller that the pieces were most likely of a neural spine from a Hadrosaur. He did mention something that surprised me. Although you can surface pick dinosaur bone fragments and possess them, you are not allowed to glue them together without a permit. Alberta laws are pretty strict when it comes to preserving our dinosaur history. Here's a photo of my pieces. Yes, they are glued together.

    Gainesville vertebrae

    Hi y'all, I bought some shark vertebrae here in the Netherlands from a guy who collected it himself in Gainesville, Florida area, a couple of verts are not from shark including this one and i was wondering from what animal it could have been. I hope one of you has an idea what it could be. Thanks!!

    Curious odds and ends

    Some things from Post Oak creek not sure if they're something or not, with exception of #3, pretty sure the one with ridges is echinoid spine and other one is fossil just don't know what. Really intrigued by whatever the yellow is, don't think it's man-made, it doesn't melt anyway.
  19. Hey everyone, been a little MIA recently. Work/life balance has gotten a little out of whack. Looking forward to sharing some of my 2021 finds soon! anyway I’m revisiting this fossil I found in Western New York roughly 2 years ago. at first when I shared the find I asked some opinions and most said cephalopod. I knew it probably wasn’t that but I didn’t really explore it further. this is from the Wanakah shale of the ludlowville formation in the Hamilton group of WNY. Middle Devonian in age. this “seems” like a spine? I don’t really know. There are lines running perpendicular to what you would expect with a cephalopod. it’s a thick black calcite shelly material. Definitely was a “hard part” from an animal. But exactly what it may be…not sure. my tentative guess is a fish spine? Idk I got some advice to tag @jdp i hope I tagged the correct member! what do you all think? Al

    Interesting find in Southwest NJ

    So I have decided to do some exploration digs in my area (Salem County) just because there isn’t much mentioned for spots and it’s not more than 1 hour in any direction for me to search. Found an area with a little help from some other individuals and the ROCKD app that put me on the Vincentown formation and had a slight success. Mostly found coral but did come up with this. Possible spike or claw? It is roughly 1 and 1/2” long. Just trying to see what it could be as not much is found in my area as of late.

    Found with Keichousaurus

    This piece is found along with Keichousaurus in Yunnan, China. That is, it’s Triassic. Any idea what is that? The “spines” measure about 10cm in length.

    Need help with identification

    Found near Lake Huron Ontario. I can see the symmetry and the darker pieces on top and that they coincide with the curved spacing below. Hard to see in pics but I’ll do my best to show. I pointed out the two less obvious in the possibility it help in identifying due to the structure etc. The other is the lighter grey square that is more obvious and visible. Thank you
