  1. Spinosaurus sail?

    Ok, so this is supposed to be a spinosaurus vert, one with part of the sail. At first glance it seems perfect, but upon further study, while trying to place it on spinosaurus skeletons, it doesn't seem to match any exactly. For one thing, spinosaurus sails, at least in the relatively insignificant amount of individuals on display, sail bones that don't go any higher than this one(it appears this is a fully intact sail vert), don't seem to get as wide. And the ones that do, then continue up and get thinner. There ARE similar shaped "sail" bones, at the transition to the neck, and tail, but those aren't as tall as this one. The main bone itself appears to be from the tail, or rear part of the sail, but....well, anywhere that one part of the bone fits well, doesnt seem to match the rest of it very well. Sadly I can't find any good images of many of each type of vert, and anywhere that has good close up views of verts, only have 1 or 2 of any type, which isn't good enough to come to any sufficient conclusions. spinosaur fossils(specifically verts), seem to be something they work with a lot, so I would be very surprised if along with all the other spinosaurus verts they get in, they would end up with the sail spine of some other animal. And if somehow so, then not realizing it.
  2. Vertebrae and something else

    Hi all, I had this in my Montana turtle thread but though it needed its own thread. i found some more bone (float) in Eastern Montana coming out of a hill near (same bank but 30 yards away) where I found a turtle fossil last year. It is a variety of bones but 2 are interesting. The one is clearly a vertebrae and from a little research seems to be reptile but what kind? The other is a piece of bone with an interesting cavity in it. Can anyone identify either one? Here are the pics. thanks, Joe
  3. My eyes are not so good when it comes to Kem Kem material. What do you guys think of this vertebrae? Is it indeed Spinosauridae? It looks to me like the process has been reworked, or repaired.
  4. Vertebrae? Waipara, New Zealand

    Forgive any inaccuracies, I haven’t hunted for fossils since childhood on the South coast of England so very much a novice. I found this whilst scouting out a new vineyard site in Waipara Gorge, New Zealand which is a pretty rich area for fossils (mostly Paleogene, and Cretaceous from what I’ve read). It was at the very top of an escarpment rather than the river banks where most are found and definitely in limestone, though I couldn’t tell you the exact type. There’s not much structure left to it (close up picture gives a better idea) but are these vertebrae and any idea what from? About 2cm diameter and 30cm in length. If anyone has any experience with this area I’d love to know more!
  5. Found in Galveston,Tx

    Found this AM on West beach of Galveston.
  6. Unknown Vertebra

    I found this vertebra while diving off Venice, Florida and I'm having trouble identifying it. I was initially told it may be cetacean. Any help would be appreciated! Bottom: Top: Side: Back: Front:
  7. Hi all, I found 3 interesting things on my last day at Onslow Beach NC. They look like some sort of bones to me. One I think is a vertebrae. Of what??? I’m hoping you all can tell me. It looks like 3 is the limit on sending pics so I will have to do several posts. If there is information on posting that I should know please point me there as well. I saw something about using the “photo FAQ-page to learn about posting but couldn’t find it. Thank you in advance. Bone 1... Vertebrae?
  8. Odd shaped rock in my garden

    Hello! first post here. I know very little about fossils but I found this peculiar rock in my garden and thought it looked like an old vertebrae. Location is Salt Lake City, although it could have been put in the garden by the previous owners. It’s a heavy rock, about 7x7 inches. I apologize if I am leaving out any important details! Cheers, m
  9. A number of vertebrae are up for sale from the Kem Kem beds. I would recommend if you have interest in any, please post them here for comment like some of you already have. I've commented on a few. Spinosaurs dorsal vertebra being offered for sale. Please exercise caution on this specimen. It has tons of fill and the centrum shape looks off. Hard to determine if this is a composite or from the same vertebra. Dorsal vertebra should look like this in lateral view. A Carcharodontosaurus centrum being offered for sale. Not sure one can identify this to any specific Dinosaur or Reptile. A Spinosaur caudal vertebra being offered for sale. Not sure what this is, not Spinosaurus. The centrum might be one but not the spines, look like crock. Spines may be composited Two Caudal vertebrae from a Sauropod are being offered. Unfortunately the one on the left is Crocodilian and the one on the right might also be one or theropod, needs cleaning up. Another similar group of Verts is being offered same comments. Neural spines like the one below typically are Croc. Okay not a vert but not dinosaurian as offered. Reptlian
  10. Fish Vertebrae?

    Would you please help me Id this fossil? Based on what I have seen on this forum, some type of fish Vertebrae.
  11. Hi everyone. So I've an old HS fb friend who found this doing tractor mowing in an area called Sand Knob. Ky is littered with these knobs, similar to a mountain range. My question is, could this possibly be an 85 million yr old fossil from the Cretaceous Period? (The last time oceans were in Western ky) It appears to be a whale vertebrae to me and others but they insist it was "dropped" or "planted". This 100% was not randomly buried by a trickster in a remote area of Casey Co. This sandy Knob region could be the banks of the Mississippian range. They are actually. Similar to how beached whales wash up on the beach, this creature, with a rise in sea levels, could very well have been deposited here. It's approximately 200mls away to the western region that known Cretaceous fossils have been found. Could this change the map in terms of Period location? Do the sandy knobs represent the banks of a past, epic event in sea levels rising? What catastrophic event would send sea levels 200mls East? Meteor? Ice caps melting? Mosasaur was known to crawl to land to give birth could this have been the leftovers of a takeaway dinner? Lol
  12. ID: Large Dinosaur Caudal Vertebra

    I just bought a large, fairly well preserved vertebra from a rock shop in Tucson. It was found in the Aguja Formation in Texas, a formation that isn’t especially well researched. My diagnosis is that the vert is most likely theropod, and the only theropod that large that is in the area and comes to mind for me is the Acrocanthosaurus. This diagnosis is leaving me skeptical. Acro bones are pretty rare to my knowledge (there are only 5 articulated specimens discovered as of now), and I don’t see any documentation of them being found in Aguja, though as I said before it is not well researched. My only other theories are that this is from a Kritosaurus (which seems unlikely based on the size and shape), or that it is some other saurischian that isn’t documented in the formation yet. If I could at least get verification that it is theropod that would be very nice. This purchase will either have been a pretty good deal, or an absurdly amazing one. We’ll see, and thanks for helping! Bone is 6.75” long, 4.5” wide at widest point, and 4.75” tall at tallest point.
  13. Vertebra ID

    I scored this nice vertebra from the discard pile outside the geology building at a local University. Absolutely no context. I suspect it will not be possible to I D but it's worth a try.
  14. Potomac Vert

    On Sunday I found this interesting vertebrae on the Potomac north of Purse. I have no idea what it is despite several hours of looking at vertebrae online. I guess it could be a modern one. My thought is that the more material I collect, the easier future IDs will be. Any ideas? Thanks for looking.
  15. While descending from the top of our hike up Mission Peak in Fremont, CA, a friend and I came across what we suspect is a fossilized vertebrae. After doing some quick research online, I came across the following excerpt: "Some 3 miles east of the low hills and lying in the Mission District is a much taller ridge, Mission Peak, 2517 feet above sea level. Millions of years before the Pleistocene, sediments that now compose the Mission Peak ridge were deposited by both marine and fresh waters. These sediments are now a rich source of marine fossils, many of them clams and snails. Also, remains of Desmostylus, a mammal with characteristics between those of a sea cow and a walrus, have been found among the remains of seashells. These fossils were buried under marine water during the late Miocene time, or about 12,000,000 years ago. The Miocene is one of seven epochs of the Cenozoic era." Source: http://cnhm.msnucleus.org/Pleistocene/FossilBearingSediments.html I failed to take a measurement, but as I recall this object was about the size of a lemon. Can anyone help confirm if this is a vertebrae or provide any additional information? Thanks for your help!
  16. Blue what vert?

    So, found just the disc part sticking up from the bottom of the marl. I knew what it was and started digging around it and found all three sides to it extending. However, after an hour of digging around it and down 3.5 inches I discovered it was broken apart and pulled just the vert part out. I will be going back to pull the other sides out, but the disc part measures 3" across and 3.5" deep/length. From what I have read up on tonight seems it is from a blue whale. I was 20 miles from the coast of Charleston, Ladson area. Many ripples of Eocene, guessing, possibly Miocene. Along with this there were many scattered rib bones, found great white teeth, and nice verts around 1". Am I correct in guessing Blue Whale dermal vert.?
  17. Dinosaur or mammal vertebra

    Not sure if this post should be in Fossil ID or Is it real? Saw this vertebrae in a local shop. Hoping for some info before purchasing. It's labeled as a sauropod vertebra from the Fox Hills formation in Jordan, Montana. It's approximately 5 inches wide, 3 1/2 inches deep and 3 3/4 inches tall and weighs 621 grams. It's obviously a vertebra from a large animal. My question: is it this truly a dinosaur vertebra or perhaps from a large mammal? Sorry if the pics aren't the best - the store lighting was challenging. Thank you for any and all help.
  18. Bone fragment - Miocene - Maryland

    Hello all! I have what I believe to be a bone fragment from the Calvert Cliffs area of Maryland. I tried to compare to various vertebrae and other bones online but considering this is a fragment I didn't have too much luck and figured the experts around here might help! "Rear" face: "Top:" "Bottom:" "Front" face: I could be mistaken but it just has the weight and feel of something other than wood or whatnot. There is quite a bit of gunk still on it that I will try to work off. The groove on the front and the "wings" definitely make me think it is a bone of some kind. Thanks again!
  19. NJ Cretaceous Unknown

    I found this in my early collecting days (late 90s, early 00s) in one of the typical Monmouth County Cretaceous stream. The texture doesn't at all say bone to me, but that notch has me wondering.
  20. Multiple IDs Requested

    Beautiful Day. Cold in the morning, but warmed up as the sun came out.. Same with the fossils. Initially , only small shark teeth,, but later (deeper) lots of interesting stuff. 1st, Can we tell by size whether this is Paleolama mirifica or Hemiauchenia macrocephala . Not sure but maybe there was a jaw down there. These seem to be 2 M3s, with exact similar color patterns. A Vertebrae... Dolphin or maybe Armadillo ??? and then this...I know WHAT it is.... a walnut...but it is hard like a rock and clinks!!!! Can a walnut fossilize? Whether or not it is a fossil, what happened to the shell? Just sharing an unusual find? Thanks for any/all comments...
  21. Kem kem vertebrae

    I bought this partial vertebrae about a week ago from a moroccan dealer for a very good price (I'm currently trying to identify many vertebrate fossils from Kem Kem, and this is somewhat a pause between two spinosaurid caudal vertebrae and a very big crocodilian mandible articular bone). Since many of you are way more experienced than me regarding moroccan vertebrae, I'm searching for more opinions. This small/medium sized specimen lacks most of the processes, but has some recognizable elements. It is laterally compressed and has a small keel running in its ventral region. I identified It as a caudal vertebrae, and the dealer told me it was a theropod. I don't think he had the skills to seriously identify anything, and I can't understand if It really is a theropod or a crocodile.
  22. Hey guys, the storm up north is churning up some amazing finds! I'll be posting over the next few days my finds but I wanted to know your opinion on this very large vert. I'm thinking whale or mamm/masto. Let me know!
  23. Socket bone or vertebrae?

    I found this in a stream bed in central Ohio. Looks somewhat porous like bone. Could anybody help me identify this?
  24. I traded this piece in this forum few months ago, and i heard this is spinosaurus's neural spine. After i received this I searching and trying to match this bones with spinosaurus's neural spine and sail bone. They looks pretty similar with this piece but not perfect matched. So, I can't sure what is this bone piece is.. I hope i can identify this clearly. Do you have any idea of this pieces? +I feel really embarrassing about i wrote 'Kam Kam' on title... now i edit that. I feel i need to more study again It's almost 30cm long. And here is more details. Thanks for your help.
