Hi All, I acquired this piece of fossilised bone fragment recently and was assured that the specimen was Spinosaurus and came from the Kem Kem group, unfortunately I was not able to gather which formation it was from within the group. Although this piece is fragmentary, its hour glass shape and the thin ridges along each side give me hope that someone would know where on the skeleton this bone is from. I've done some quick research and found that Spinosaurus vertebrae are of similar shape but I am not 100% confident that it is a vert. If anyone has any idea which bone it could be, that would be brilliant (apologies for quality of the side images, my camera had trouble focusing on the thin ridge)

Spinosaurus Tooth, Real or Fake?
micaham posted a topic in Is It Real? How to Recognize Fossil Fabrications
I recently purchased this Spinosaurus tooth from the Kem Kem beds in Morocco, it’s 3 3/8” long and supposedly has no repair or restoration according to seller. Does the tooth show any signs of repair or restoration? Is it entirely real?

Spinosaurus Jaw Piece with Tooth
ConnorR posted a topic in Is It Real? How to Recognize Fossil Fabrications
I saw this item for sale, said to be a Spinosaurus jaw fragment with an associated tooth glued on. Is it a composite, and does it belong to Spinosaurus?.thumb.jpg.411114bb290b77f5e2bf334dc0a583ca.jpg)

Hello! I bought this tooth from a gift shop. It was labeled a spinosaurus tooth. I’m just wondering if it most likely is a spinosaurus tooth, or a crocodile or something else? Thank you!

Spinosaurus tooth - any issues?
bubbleobill posted a topic in Is It Real? How to Recognize Fossil Fabrications
I new to collecting and recently received this Spinosaurus tooth from a dealer who has a great reputation online. It was not a particularly expensive tooth and although the crown appeared to be in good condition from the dealer listing (and no repairs/restoration work was listed) the root has me a little suspect. No alarm bells from the listing photos but now that I have it in my hand and can see it from all angles, it got me wondering. The first couple of attachments are the dealers listing photos. The rest of the photos are mine. The main thing that has me curious is the colour visible in parts of the tooth, especially the root - the white is very white in areas, and I dunno how to describe it, just not quite 'right'. I've included photos of the area on the root that looks a bit fishy to me (mind you due to lighting conditions this doesn't come across as white in the photos as it does to my eye) and then also some damage on the crown where you see the same tone of white - some from a chip on the edge of the tooth, and also at the tip. The dealer does accept returns, just wondering if there is actually anything suspect with this or not? I am a total novice so I may be seeing problems that aren't really problems at all, just wanted to check. Cheers

Big spinosaurus tooth with Pathology and serrations?
JorisVV posted a topic in General Fossil Discussion
Here by my new Spinosaurus Aegypticus tooth from Taouz, Morocco. It is 4 1/2 inches. The colors are less common than your regular Moroccon Spinosaurus teeth. It has 0 restoration done to the tooth, and the quality is very high. Which I find special about this one. Noticed some slight patho and serrations on this tooth too? Could someone explain the patho perhaps.

Repaired, Composite, or Fake Spinosaurus claw? How to spot the signs.
Genetic Algorithm posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good day and thank you for reading! I bought a 7-inch Spinosaurus claw in an auction and was hoping to get a second opinion on the condition and authenticity. I can send it back within a month for a full refund. I am also hoping for some pointers in knowing if is repaired or a composite. I have read many of the forums on here, but I have more questions. The length is 7 inches, but I do not have a ruler at the moment. This fossil is supposedly from the Kem Kem beds in Morocco. Any help is appreciated! Btw I do not have many fossils and plan to display this one to the public at my work if I keep it. Reasons why I do not think it is a composite or a carving: The texture and colors match on both ends of claw. They are also appropriate for fossils from Morocco. The shape and feel are good. Blood grooves follow the correct path. Reasons why I question if it is repaired or a composite: The darker brown areas do have a smoother texture and the grain is not visible in the very dark areas. How can you tell if this is substrate or cement/glue? If it is cement or glue, this piece could have been broken in half at some point, since the darker material has a concentration at the center and the tip. The blood grooves are not the exact same size on either side, though they are close. One side is wider. The darker areas do cause some "muddiness" but I cannot tell if it substrate. It is a bit lighter than I expected, but feels solid and has a similar feel and sound to other fossils when I tap it. The density feels similar to a Spinosaurus tooth, but feel less dense than a megalodon tooth..thumb.jpg.05b21eabc72bf4032e26f93d09e62d2a.jpg)

Here we go again :) - Spinosaurus was not an aquatic dinosaur.

Authentic Spinosaurus claw?
Mrhenky3 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I came across this Spinosaurus claw. I was wondering if this claw is genuine. It looks to me like it consist of multiple fragments added together. Thanks in advance. Location: Kem Kem beds Size: 13 cm

I'm continuing my search for my first dino tooth. I came across this spino tooth: is real and in good conditions, or is reconstructed?

Hi! I'm a bit doubtful about this spino tooth: it is genuine? Is authentic only the tooth? The root is real or fake? I have read online that genuine rooted teeth of Spinosaurus are extremely rare... Thank for any help.

Is it Real? Spinosaurus Tooth
Rock Hound posted a topic in Is It Real? How to Recognize Fossil Fabrications
Seeking input on this "Spinosaurus Tooth" specimen. Is it a genuine tooth? Has it had tip repair? Is the root behind the tooth genuine? How much touch up / clean up work was done to get it to look this undamaged? Is it constructed from multiple pieces? Etc. Specimen measures exactly 4 inches in length. Working with an inexpensive Android phone. I can't get an in focus picture of the end of the root. I tried many times. Not enough detail in those pictures. I can say that it's not just plain rock or fabricated matrix. It is either a tooth root, or bone-like in appearance. All input appreciated..thumb.jpg.27e9d019d803e83b7e8be0b4636ee3a1.jpg)

online seller seems to have several of these claws. I was under the impression that they're pretty rare, so I'm thinking something is up. I understand that online is first red flag, but wanted to get your assessment anyway. Here is one of them. Thanks in advance.

Hello there! I'm collecting fossils since I was a kid and I have a question, so I hope anybody can help. I bought a fossil years ago at my local fossil and mineral fair in Germany from a maroccan trader. It should be a Spinosaurus vertebra. But I'm doubting about the authenticity. It was quite cheap. But it's a real vertebra? (and even from Spinosaurus?) Thank you! greetings, Lilian

Another rooted spino tooth
Nanotyrannus35 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this spinosaurus tooth online. It seems to have a mostly complete root. However, it does look like it has been repaired, and there might be some restoration, but I can't tell. Thanks for any help. The tooth also appears to have some striations along the carina.

Spinosaurus Vertebra / Pachycephalosaurus Vertebra
darthdasko posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi guys! I started venturing into fossil collecting recently. If anyone can help me, I have questions about a "spinosaurus vertebra" I bought. I started to distrust the seller after I had already made the purchase, although the reviews are practically 100% positive, I was afraid after some research and observing other cases. I didn't know the forum before to guide me, so what do you think? And taking advantage of the post, I also have doubts about this Pachycephalosaurus vertebra, what do you think?

Paper finds strong support for aquatic habits in spinosaurids, associated with a marked increase in bone density. Paywalled paper https://www.nature.com/articles/s41586-022-04528-0 Bone density of Baryonyx appears closer to Spinosaurus than Suchomimus which has lots of implications in its adaptation to aquatic life National Geo https://www.nationalgeographic.com/science/article/spinosaurus-had-penguin-like-bones-a-sign-of-hunting-underwater Smithsonian https://www.smithsonianmag.com/science-nature/heavy-bones-helped-some-species-of-spinosaurs-swim-180979775/ Phys org https://phys.org/news/2022-03-dense-bones-spinosaurus-underwater.html I wish we see some publications on other theropods in the KK not just the headliner Spinosaurus

Large Spinosaurus Aegyptiacus vertebra

Hi everyone! I’m an amateur fossil collector who wants to collect and learn more about fossils and hope to learn more through this forum. Growing up I’ve always been fascinated by dinosaurs and sharks in particular. Today I went to a fossil show and found a vertebra that I found particularly fascinating. I bought it not knowing exactly what it was so I can chase the thrill of learning what it is and why. The man I had purchased it from had said it was from a spinosaurus. However, I’m skeptical because he was also marketing a tooth as an allosaurus tooth. He was honest man and had told me that he wasn’t exactly sure what kind of tooth it was. Later, I found out the tooth in fact belonged to a carcharodontosaurus based on the matrix. Luckily I didn’t spend money on what was thought to be an allosaurus tooth. Nor did I spend too much on the vertebra. Now I don’t have a lot of information to go off of. I’m not quite sure where exactly the vertebra came from nor do I know how the gentleman came to own it. All I do have are the photos that I took of it. Judging from the looks of it, it does seem to have come from Morocco based on the color and other specimens I have seen. I also tried to study the skeleton of a spinosaur to see if I could ID it using reference photos. It’s difficult to tell but if it did come from a spinosaur, I’m thinking it’s part of the neck. Anyways, if I could get some help that would be great! Bonus points if you could tell me which part of the animal it came from.

Saw this tooth while browsing. Looked so off and maybe entirely reconstructed or fake. Any ideas?

Enormous Cheap Cheap Cheap Spinosaurus Tooth
Guest posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good evening everyone, today I have the fantastic idea to bought 5.5 inch spinosaurus tooth. The price was 4 times cheaper than normal. The seller told me that it was the same tooth but glued at four different parts. Please see at the attached photos the red flags. In the fifth photo you can see many black spots on the tooth. Are these black spots part of the fossilization or are they part of a glue made by human action? Do you think I was right to buy it or would you have discarded this tooth?
