Any red flags with this Spinosaur claw?
msantix posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I know claws have been discussed quite a bit before on the forum, but i wanted to ask about this Spinosaur hand claw. It is said to have about 5% restoration and is over 5 inches long. Can anyone spot any red flags to be wary of or does it look good? Thanks. -
Is this a spinosaurus phalanx? I believe it's supposed to be a finger, not a toe. Ive done a lot of comparing, and it just doesn't look right, although it's from a source that I trust, and am believe that most of their ID'd stuff is correct, although I believe I've seen a few(very small %)that have been incorrect, over time. I believe it could be a slightly mishappen phalanx, specifically the base/back/end closest to the hand itself. *kem kem

I haven't been able to place it, yet. I figure if I come across someone has familiar knowledge of bones like that, there's a much better chance of recognizing it, than someone just using pics and stuff.

I'm having a hard time finding any images of anything other than the outside/side view of a spinosaur pelvic bone. I'm trying to see what the bone looks like in general, but all too many times...WAAAAAAAAAAAAAAAAY too many times I'll spend forever unsuccessfully trying to come across pictures, images, or diagrams that show what a bone looks like from other angles than what you see be looking at the skeleton from generic angles, like this one. In some cases it's not TOO difficult, but even those common bones have areas that you can never see, unless you get totally lucky and happen across it, OR if there's maybe, hopefully some site/database that specifically shows what entire bones look like. I doubt that, but I know there's perfect diagrams floating around on the web, but I can't seem to find any *im just talking about dinos and other extinct animal bones. I'm sure there's plenty of sites with images of every conceivable angle of every bone from humans and common living animals, but I'm not looking for that kind of thing.

This looks a little weird to me. Does this seem like the real genuine article to you guys?

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.

So a while back I was given these fossils along with a Spinosaurus tooth. He said that they were all from the same area and that they were both vertebrae. I can see the touch up on the larger one obviously but it still seems real because of the spongy meterial from the one view. I was just wondering if you could ID these for me I’m pretty new to the fossil scene. Thanks.

Hello friends. I am new to this forum and I would like to show you my teeth and dinosaur claw so you can help me identify them, tell me if they are repaired and tell me what their value is. I hope you like them.

I have been looking at this ulna bone from the kem kem, and wondering if a large isolated bone like this can be identified. It is about 26.5cm (10.4 inches) and looks like a chunk of one end in missing (which might make it harder to id). It seems to resemble this megaraptor ulna....

Fourth cervical vertebra of a Spinosaurid. Very likely Sigilmassasaurus due to the short dorsal spine and proportions of the postzygapophyses.

Skull bone of a young Spinosaurus aegyptiacus, partial left quadrate. Has some prep damage.

Red Flag on Spinosaur verts
LordTrilobite posted a topic in Is It Real? How to Recognize Fossil Fabrications
So I was browsing our favourite auction site, and I came across these interesting specimens. The seller claims these all belong to the same individual, while at the same time, strangely, they are selling each bone separately. And while these bones are definitely real Kem Kem bones, I'm posting it in this forum because there is reason to believe the information that these belong to the same animal is suspect. All of these are sold as being from one individual Spinosaurus. This first one is definitely a Spinosaurid cervical vertebra. a fairly nice one. But the rugose triangular area on underside shows that this is in fact from a Sigilmassasaurus, one of the Spinosaurids from Morocco. From the length of the vertebra this can be placed somewhere in the back of the neck of the animal. Next specimen is also a Spinosaurid cervical vertebra. Though due to damage this one is harder to identify as Sigilmassasaurus. Again due to the shortness this seems to be a cervical vertebra from somewhere back in the neck. The dorsal spine though worn, seems to be not that big. So this might point towards it being Sigilmassasaurus as well. So seems fairly plausible if the seller says these belong to the same individual right? Now here comes the problem. This third specimen is listed as belonging to the same individual. But this is clearly a cervical vertebra from a type of crocodile. Since it's nice and complete we can see which way is the front and which is back. The front of the centrum looks to be concave, while the back of the centrum here is convex. This is typical of some crocodiles. But on Spinosaurids it's the other way around, with the front of the centrum being convex and the back is concave. So with that this specimen casts doubt on the whole claim that some of these specimens belong to the same animal. Which is too bad 'cause the fossils seem pretty nice. There were some other specimens as well. But these three were clearly identifiable. -
I have some new finds these I hope maybe from pterosaur as seems to have characteristics. However problem is I only have phone camera and cannot edit to make smaller so pictures will only come very slowly.

So I bought this piece on the internet... It was advertised as a croc limb from Kem Kem. Except it wasn't a croc limb. Upon closer inspection of the images, I figured this was a theropod quadrate bone instead of a croc limb. So now that it has arrived and I could get a proper look. I've come to the conclusion that I bought a part of a huge Spinosaurid skull. It doesn't look anything like the quadrates of Abelisaurs and Allosauroids, while it does show close similarities with those of Spinosaurids. It's a right-hand quadrate bone that is almost complete with an articulated quadratojugal fragment attached to the side. It's huge and must have come from a skull of well over a metre long. Articulated fossils from Kem Kem are really rare. And better yet, since I bought this as a croc limb, it was only like 60 euros. So needles to say, I'm quite happy with my accuisition. This will be a fun one to clean.

My collection is quite meager compared to everyone else's, and most were bought, but I was excited to show it off anyway. I received two riker cases yesterday (though one was missing two pins, so I haven't put it together yet) to put my shells in from my Walton on the Naze finds. I'll need a deeper case for some of the other shells that aren't displayed. Other than the shells and the two corals on the sides of the knightia fish, the rest have been purchased.

Is it possible to ID this vertebra? Thanks ...

Spinosaur Tooth W/ Possible Restoration
Trilobiting posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this 2 3/4 spinosaur tooth being sold on a popular auction site. It looks like it's been painted to hide enamel peel. About how real is the tooth?
-
Hi guys, I am really doubting about these two teeth. I bought them as pterosaur, but I really think the left one is an infant Spinosaur (it has corrugations on te tooth), the right one is anyway Pterosaur I think. What is you guess?

I bought some new cool stuff at a local show. I only bought Moroccan material. A few Mosasaur pieces and stuff from Kem Kem. I've only started cleaning and will research them a bit more later. So I thought I'd share some pics first. I also got some new display items that will be nice to showcase some of my other stuff in. From left to right. Top: First there's a chuck with two roots and one tooth. There's also some bone fragments that look like they could be jaw pieces. Will be a fun prepping project. Then there's a Prognathodon tooth that isn't the prettiest but it's really big and it was cheap so I had to get it. And at the end there's a Plesiosaur vertebra with a partial neural arch that will be fun to clean. Bottom: On the left there's a neural arch from a Spinosaurid. I compared it to the recent reconstruction of Spinosaurus and it looks like it's a pretty close match with some of the first dorsal vertebrae. Middle top there's a small caudal vertebra. Middle bottom there's a fish jaw. And on the right from top to bottom. A possible distal femur. A metacarpal/tarsal? And a possible proximal tibia. All three are hollow and probably Theropod or bird. So I have some research and cleaning to do! Really big ugly Mosasaur tooth. Mosasaur tooth and jaw fragments. Fish jaw. Distal femur. It's very asymmetrical as well. Metacarpal or tarsal. The head is almost symmetrical but the shaft seems to be angled more. Spinosaur neural arch from a different angle. Roughly a dorsoposterior view. Since it's not very complete on one side this will make for a great piece to scan and digitally mirror so that I can recreate a bit of the missing pieces. So I'll be having fun with these pieces for a while.

Vertebral process of Sigilmassasaurus. This is likely a mid cervical vertebra. It also bears close resemblance to the Spinosaurus maroccanus holotype which I consider to be synonymous with Sigilmassasaurus brevicollis.
-
Anterior dorsal vertebra of a Spinosaurid (likely Sigilmassasaurus) with series of scratches on one side. It is likely that these scrathes are gnaw marks from different animals due to the different sizes of the marks.

Tooth of a spinosaur.

I have this anterior dorsal Spinosaur vert from the Kem Kem beds. But I noticed these small vertical marks on one side of the vert and figured they might be gnaw marks. They definitely seem pretty worn down so I don't think they are recent. Any ideas what could have made these marks? Vertebra overview. Scratch detail.

Hi, Two weeks ago I could lay my hand on a vertebra of what I think is a Spinosaur. The total height is 16 cm and the diameter of the vertebral disc is around 10,5 cm. The underside is still burried in matrix. Seller said it was from South-Morocco. Questions I have are : - is it genuine ? I only ask the question because the price was rather low ($75). - is this indeed of a Spinosaur ? - was this from an adult specimen based upon the size ? - was this part of the neck, back or tail section ? There is quite odd depression or hole which is drop-shaped in one of the vertebral extensions (see second photo). Could this be a bite mark or is it just a part of bone that was weaker and eroded away ? I know : a lot of questions, but I would appreciate any help in answering them ! Greetings Hans
