Curious about a couple of the fossils I found today, the first one I’m not sure what it might be, second one a hadrosaur vert but I’m wondering if the damage to it isn’t simply from erosion. Maybe bite marks or some pathology? dinosaur park fm

I found these pieces all in the same creek bed that had been eroded by winter rains I guess. Anyway, I believe they are all part of the same fossil because they were in the same spot. I have no clue how to determine age or what is. It looks like some of the bone had damage/scar tissue when alive...maybe? IDK, any help would be appreciated.

New Jersey Nodosaur Donation
njcreekhunter posted a topic in Partners in Paleontology - Member Contributions to Science
Hey everyone. Last summer I found an interesting piece of late Cretaceous fossil bone with a unique texture in New Jersey. It was later identified as a Nodosaur osteoderm by Ralph Johnson. Dinosaur material in general is rare in New Jersey and this specimen to my knowledge is the second Nodosaur osteoderm found in the state of New Jersey. Recently, I had the pleasure of donating this specimen to the New Jersey State Museum. I am honored to be able to contribute this specimen to science for future generations to study. Here are photos of the specimen.

Hey everyone! I’ve been looking for answers for years now on this tooth I found. It’s 3 inches long, and doesn’t have any enamel left. I found it on one of my shark teeth journeys back in 2013, after a Tropical Storm passed through. I know this is a type of tooth, as I can see where the root attaches to the gums. But the only closest thing I can find that resembles this is a pterodactyl tooth. Now, I found this in North Florida, and the beaches are replenished with sand from the St John’s river. So very cool stuff I’ve found, I do have a great collection but this particular tooth I’m stumped on and so is two professors that I’ve asked. Any ideas?

Soft tissue blood vessels and cells from a Tyrannosaurus rex bone were discovered by Dr. Mary Schweitzer in 2004. Ever since, scientists have wondered how such soft tissues preserve into the fossil record. Finally, we have an answer, based on organic chemistry theory. Below is a link to a recent news article that explains these ideas in layman’s terms. The article itself describes a recently published, peer-reviewed research paper: https://phys.org/news/2023-05-dinosaur-tissues-deep.amp

Hi everyone! I bought a batch of fossils from Tegana Formation, in Morocco. Among the fossils there are those reptile teeth: The seller assures that the five in the top row are Spinosaurus aegyptiacus (or at least Spinosaurid species). The three in the bottom row are reported as Elosuchus cherifiensis. The seller is reliable, however I noticed that the teeth are all very similar to each other. Is there a possibility that they all belong to the Spinosaurus or Elosuchus species? Is there any way to tell the two types of teeth apart? Below I put a few photos of the individual teeth.

Hi, I went to the fleamarket and bought these. One is some kind of shark tooth, the other a crocodile tooth from the miocene I believe. What do you think?

Hi, went to the fleamarket and bought this. I think they’re some pseudosuchian teeth.

Hey everyone, I have a vertebra I just finished preparing that I was looking for an ID. It was found in the Hell creek formation near Ekalaka Montana. It is a little crushed and not complete unfortunately but the centrum looks a little geometric to me so I have a tentative ID of a dorsal hadrosaur vertabra. It is 10.5cm long by 15.5cm tall by 6.5cm wide. I would appreciate confirmation or to figure out if it's something else as always thanks for your time and expertise.

I am a big fan of jurrasic sauropods and I therefore spend most of my time on preparing what is left of them. However, for a change I now started working on a slab of rock that seems to contain a series of fused sacral vertebrae by a theropod. The verts seem to belong to Allosaurus. Maybe not as cool as a sauropod fossil but I think that Allosaurus was a fascinating creature as well. The bones have been collected many years ago at Dana Quarry, Teen Sleep, Wyoming.

Hi all. These are four theropod teeth from the Kem Kem beds that I am not sure about how to assign them. I was hoping you could have a look and let me know what you think. 1. A 3 cm long tooth, I think this one might be Carcharodontosaurid. 2. This one is 1.9 cm long. Distal serrations are slightly less dense than mesial ones. 3. A small one, 1.5 cm. Hard to measure, but mesial denticles appear to have a slightly higher density. 4. A 2 cm ugly one Thanks! Let me know if you need more info or pictures.

Hey guys, I saw this listed as a suchomimus tooth. I know suchomimus tooth is quite rare and I don’t have much experience with it. Do you guys think it’s really a suchomimus tooth?

Hi everyone! I'm helping out a new buddy of mine with this one. He acquired this bone a few years ago under the pretense of it being a "Triceratops hip or leg bone". He's currently selling it and the rest of his collection off to pay for some medical expenses, and I've been helping him try to verify the ID on some of his things since the original seller's IDs for several have been, well, I disagree with some of them. I'm just going to leave it at that. Anyway after contacting the original seller for some more info on his collection, and some remarks by several interested parties it came out that this bone might have been mixed up in it's original ID and is actually Sauropod, specifically the pubis. We're currently trying to get more info on locality, but in the meantime I thought it would help to get an independent opinion on what this is most likely from so I'm posting on his behalf. He described it as roughly 21 inches long so about 53-54 cm. While we wait for more potential proximity info (if it even exists anymore) if there are any other measurements or spots that need better photos tell me an I'll let him know. Any insight is appreciated as always!

Symbiosis between Cretaceous dinosaurs and feather-feeding beetles

I acquired this from a person that had owned it for some time who knew even less than I do about fossils. He got it at an estate sale from someone that did collect fossils several years ago. Due to the box having a label in it that said Allosaurus, he always assumed it was an egg from that animal. He had no idea what a theropod was, looking at the egg it remined me of some Hadrosaur eggs I had seen. It is too old to be part of the current crop of eggs coming from Asia. It was a nice fossil and I acquired it, Now, I would like a more knowledgeable option. It meauseres about 17x10 cm Thanks Robert

Hello everyone, I have been looking at a pair of eggs on matrix. I believe they are real and good, they should be 'Oviraptor?' or perhaps another species , perhaps someone can help out. but just to be sure I want to post them here and perhaps get some opinions . They should have a small repair at the eggshell and at one that I have marked there was a crack that is repaired. Thoughts? Nice weekend everyone! f78d4a5feab7439096f0650fbba37ce4.MOV

Hello, My fiancé and I were hunting for meteorite fragments and found this very unique 'artifact' at her family ranch in Starr County, Texas. I have no idea what it is and want help identifying it. A very uneducated guess is that it may be a dinosaur egg with ancient carvings - total guess. The lines around the 'eye' are raised.. not carved in. Apologies if I am using incorrect terminology. I just want help in my quest to identify it. There were quite a few arrowheads found near this 'artifact' as well. Any ideas or suggestions welcome in helping identify this! Thank you

Hi everybody. First of all thanks in advance for your help with my question. The pictures are of a tooth I bought from Morrison formation of moffat county. The tooth is labeled torvosaurus and is very large at almost 4 inches. It is not in the greatest condition though and appears t have some gap fill and is missing the majority of the enamel. I understand the tooth is not in great condition but I’m wondering if it at least looks to be all from the same tooth and not a Frankentooth. It seems to have similar texture and root etchings up to about 75% up the tooth. At that point it’s a little different and that’s where the gap fill is. However it seems the enamel on this part matches the enamel of what remains on the other part of the tooth. Any input would be appreciated. Thanks! Dean
