Hi everybody I have been sifting through some micro matrix off of a hadrosaur pubis I have been working on and was hoping to get some ID's. I'll label the specimens by number to aid in responses. The first is this therapod tooth that I was thinking could be dromaeosaurid, possibly Archerorapter because of the ridges on crown but unfortunately the tooth isn't in wonderful shape. The tooth CH: 5mm CBL: 3mm CBW: 1mm and the distal Carina are 10 per mm. There aren't any distal Carina preserved. 1. Next is what I think as a gar dermal plate and the several other pieces like it but with different patterns. The dermal plate 2. The other patterns. 3.4. Next is an odd bone fragment that I haven't the faintest ides of what it is. 5. Probably my best find would have to be this vertebra that I think is a Scapherpeton tectum trunk vertebra that I was beyond thrilled to find. 6. I feel like this next one is a tooth and makes me think gar but is fairly beat up so it might not be identifiable. 7. Here's a fragment of bone that is only diagnostic in the fact that it is hollow. 8. Here's some of what I think are gastropods with a small amount of shell remaining. 9. Here is a curious looking fragment that is only half there but seems to have some enamel? 10. And finally here is what I'm pretty sure is just a fragment of tooth enamel. 11. As always think you for your time and knowledge I look forward to hearing from you.

Made a second trip to North Carolina's Black Creek group last week, and was definitely rewarded! Lots of interesting finds, the best of which are shown below: Deinosuchus rugosus (D. schwimmeri) teeth, osteoderms, skull fragments, and one MASSIVE coprolite. Also, the bottom right bone is either mosasaur or crocodillian/alligatoroid, I believe either from the hand or leg, hip maybe, but not sure on the exact ID.. Dinosaur teeth! One's definitely hadrosaur, the other I have as the broken-off, enamel-less tip of an indeterminate therapod crown..you be the judge on whether that one's a tooth lol. I think it is, the break has the exact shape of a broken-off Carcharodontosaurus spp. crown tip I have.

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. -
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? -
I found this tooth in my Aguja matrix and the serrations are way larger than any of the other teeth I've found! I can take more pictures but this tooth is so tiny and I'm unsure of it's exact measurements.

Here is a small tooth, probably a juvenile therapod, from the Hell Creek Formation, Garfield County, Montana. The collected horizon reportedly produces material belonging to 'Nanotyrannus'. Any thoughts on what taxonomy this tooth may represent? It show feeding wear and nice distal serrations, but no mesial.

Found this in Big Brook Nj. To me it looks like a phalanx or toe bone of a dinosaur based on shape, texture, color from research I did. Would appreciate any opinion you may have, please. My first post here, Great site and excited to be part of this fine community!

While digging holes for sage bushes at my mother's house in Granbury, we found this. Both pieces appear to fit together. Is it a fossil? If so, of what? Should we dig some more? Or am I totally wrong? I have additional photos. Thank you.

Hey y'all. I've had this therapod tooth for a while, and I'm wondering if an id can be placed on it. It's completely shattered unfortunately, so I don't expect an id to be easy. It's from the Hell Creek formation. It was labeled as T. rex, but I'm not convinced. Though, I've very little knowledge of dinosaur teeth. I've attached various photos of the tooth in question, and some reference serrations from a probable rex. Thank you!

Does anyone have an idea of what this might belong to? The claw is approximately 2 inches long. This claw was found in the Judith River Formation. Seller is claiming it’s a Therapod of some sort. Any input would be appreciated! Thank you.

This one inch robust tooth came out of Hell Creek Montana and labeled as Albertosaurus. Does that appear correct? Can one tell the difference from other therapods in the region? Thank you in advance

I just obtained a Nanotyran tooth that is 2.2 inch. It's beautiful but wanted to know what causes the unique difference in the color of the teeth between the nano teeth or any tooth for that matter. Golden brown vs Chocolate brown vs black vs the variant that I have. Thanks in advance.

First post, but frequent follower of the page. I just came across a toe bone from an estate sale. It looks Hell Creek by the bone material and by what else was in the collection. It is definitely theropod. Would any of you be able to ID this? Any insight would be helpful. Thanks! Sean

I recently saw this therapod indet. tooth for sale from the Lourinhã formation, Portugal. It measures 21.99mm x 10.40mm x 3.78mm. How does it look and are those lines cracks/wear or natural? Also does anyone have any idea on the ID? How is the quality and should I consider buying it or pass it on?
-
Does anyone know what these lines are on this tooth from the Lourhina, Portugal and do they help in ID?
-
I recently saw these teeth for sale online. Which of these in everyone’s opinion is of highest quality and easiest to ID? And which are your favourites? Also am I correct when I say the lines on the second tooth are seen in some ceratosaurus teeth? These teeth are from the Lourhina of Portugal.

A forum member recently offered these teeth. One as partial torvosaurus or megalosaurid and the second as dromaeosaur. How rare are they and what is the exact ID if possible?
