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?

Strange Spinosaurus fossil.
ConnorR posted a topic in Is It Real? How to Recognize Fossil Fabrications
First off, this is my first time posting on the forum. So hello everyone! I just got my hands on some Spinosaurus fossils, allegedly from the Kem Kem beds. Both are from a seller in Arizona. One of them is a hand claw, as seen below. I'm not 100% sure that it's from a Spinosaurus, so I hope someone can tell me. But it seems very real. The other specimen, though, has some bizarre properties. I thought it might be fake. But after doing some tests on my own, I'm only more confused. These are the vertebrae that I bought. The first thing you'll notice is that they appear crushed, flattened and distorted. In the last photo, you can see some tool marks on the back of the second vertebra. But I noticed some strange things. Firstly, it makes a hollow-ish sound when tapped. Not the matrix, just the bone. Secondly, the bone has a faint odor that's hard to describe. I did a scratch test with a small pick to see what was up, and it's VERY soft. It's somewhere between 2 and 3 on the Mohs scale. I can't scratch it with my fingernails, but I can scratch it with limestone, producing a fine white powder. I scratched a little deeper to see if the smell was because of paint, but found that it's the same deeper down. The matrix is also fairly soft. I can scrape it easily with a steel tool. Confused, I did an acid test with vinegar to see if maybe it's carbonate or something. It didn't react, but I found that the bone absorbs liquids very slowly, even though it's not porous to the naked eye. And by slow, I mean it takes 20-30 seconds to absorb a drop of liquid. Another strange thing is the coloration. It's mostly white, with orange in some parts. But in the following image, you can see that some of the cracks have a reddish color. Now notice that there are small fossil fish teeth and vertebrae in the matrix. I wanted to see if they had the same properties as the large bones. If they don't, then maybe that would indicate that the Spinosaurus bones are fake. Maybe the matrix is made of crushed rock that just happened to have fish fossils in it? So I did a scratch test on the fish vertebra in the following image to see how hard it was. I found that it has exactly the same properties as the larger bones. It's the same color, it has the same hardness, and it produces the same fine white powder when scratched. The fish vertebra is only 3mm long, and there are many smaller fossil fragments throughout, all with the same strange properties as the large bones. At this point, I'm convinced that it's real, and that it's probably Spinosaurus. But beyond that, everything about this specimen is weird. Does anyone have any ideas about what the deal is here? How could this have formed naturally? What mineral(s) is it made out of? Or if you think it is fake, how do you think it was made? Either way, do you think $500 was a good deal?

Hello everyone, Mid or early February 2022 Paleontologist Nizar Ibrahim did a talk of 60minutes about the Spinosaurus. I stumbled onto a small piece of the lecture while scrolling social media, I found it very interesting, but I can't seem to find it online. Does anyone know where I can see this footage or stream it? It would be very helpful Thank You

Hello - Some time ago I bought two partial bones, both from Kem Kem beds, Morocco - The specimen on the left in the photo in my opinion could be the final part of the ischium of a theropod dinosaur (roughly 21cm x 21cm- possibly Spinosaurus?) and the other specimen a partial vertebra (21cm x 13cm) of the same species - I'm not an expert and I'd like to know other opinions about the ID of the two fossils - Thanks in advance, Fabio

Hi guys I've known this piece for like 10 years and the owner finally sold it to me. The size is 10,5 cm and the only original tooth is the middle one... Need some help in the id to understand if it's crocodilian or spino indet.

Hello, recently I have found a quite interesting dinosaur spine section. The seller claims that this is: Museum Quality Spinosaurus Dinosaur Spinal Section with Huge Vertebrae and Rare partial spines 55 Million Years Old Measures 12.5" x 10.5" inches. What do you think about the fossil? Best regards
