I finally took a trip to the North Sulphur river last week. There have been a couple good rains so I was hoping that would uncover some stuff. The last couple of trips in 2021 were terrible. All muddy and picked over. This trip was still pretty muddy and little in terms of quality mosasaur material. However I went low and found a lot of smaller material. I wonder if the recent muddyness of the river is due to the lake construction or if the river just hasn't had enough rain lately? Is picture 2 an enchodus jaw? I believe the pictures of item 3 are of a really chipped piece of mosasaur tooth. Still never found a whole one this color. Are the pictures of item 4 pachyrhizodus? I have seen people say these are really small mosasaur but I have always doubted this. Any way to identify item 5? Maybe xiphactinus? Item 6 are the few decent mosasaur pieces i found. Is the second one a phalanges bone? Any idea about 7? It is heavily fossilized so i was thinking cretaceous but the shape makes me think of more recent like pleistocene. And my final question. Is item 8 coprolite? Im terrible at identifying the stuff. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

I have seen this for sale, however the seller states that they don’t know if it is real or a replica. I’m thinking it might be worth taking a risk on, but the air bubbles in the bottom are a red flag. It’s clearly another layer to the top so I suppose it could just be something added to the fossil to strengthen the piece. I’m also thinking that such a piece wouldn’t usually be worth making a replica of. What are your thoughts on this; worth the risk at a low price?

I have a few vertebrae I was hoping to get identified. These are 3 that I don't have any others that are alike. I tried to search online and the oval shaped one looks like possibly a Pachy but wasn't sure. These were all found on the Judith River Formation Montana, Hill County. first 4 is the one that I thought was Pachy, 2nd 4 I am not sure, 3rd 4 might be Hadrosaur?

Hi guys I’m from NSW Australia and have been finding teeth for the last couple years and just wondering if someone can help identify a tooth and two vertebrae. Thanks!

I have a collection of 22 Hell Creek Vertebrae, and I have no idea what any of them are.

Hi all! Lovely little something I acquired recently. Seller said Struthiomimus, just wanted to verify and see if anyone could provide insight on differentiating altus from sedens from potentially something else like Anzu, raptor, or Tyrannosaur. Measures 7.5 cm tall, 7 cm long, 3.8 and 4.2 cm wide centrums. Found in powder River County Montana. Was apparently found "crushed" and then repaired.

Found in Kansas... Can someone tell me what it might be??? Let me know if anything else is needed...

A couple larger dino vertebrae I found on the Judith River last year, I believe the larger round one is Hadrosaur but not certain, the longer rectangular shape vertebra I have no idea. I was hoping someone would be able to help identify.

I am sorry, I know next to nothing about fossils and most bones. I do think this is a fossil because the little areas that look like stippling are porous like the inside of a bone and the other areas are really smooth like they have been rubbed against. I could be way off base here, but I just don't know. I found this at North Topsail Beach in North Carolina, March 6, 2022.

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?

Hi everyone! So first and foremost let me say, it's not a composite. Yes I know there is some sediment where the process meets the centrum, yes it is Moroccan, yes 99.9999999% of the time that automatically means funny business but I've looked at the area really carefully and the bone connects there (might try getting rid of some of that matrix at least on one side depending on what it's from). Anyway, I'm on the fence on this one. I was comparing it to a similar thread where a fellow asked about a caudal vertebra from the kem kem which turned out to be croc but was sold as Rebbachisaurus. In the thread some pics were posted of Titanosaur caudals and this looks really similar to that versus the examples of Crocodyliforms that where shown. But before I take that leap I would like a second opinion. The dimensions are 2.25 in. (6 cm) long, 1.85 in. (4.7 cm) tall, and .83 and .75 in. (2.1 and 1.9 cm) wide on its centrum. I also included the pic from that thread of Titanosaur caudal that was posted by Troodon.

Hey guys, just saw this dimetrodon vertebrae for sale. Not really familiar with reptilian material and tried checking in the forum for similar threads for reference but cant seem to find one I could use. Also tried looking fkr similar ones for sale online but just not really familiar with reptilian material to positively ID mine. Was hoping if you guys may be able to help me with this one though and if it was possible to ID them to a species level? Cheers! PS. Currently asking for more specific locality but atm, all I have is that it is from Texas. Age Location Formation

Hey everyone! I thought I'd share a few of my finds from the past couple months and get yall's opinions. Over winter break, I went back home to North Texas and did some searching around Ammonite Beach at Texoma and the NSR with my family. At Texoma I had a nice time hammering out a few ammonites, collecting teeth, and surprisingly finding lots of smaller, pyritized ammonites that I did not expect to be there. The NSR was a bit slower, but I at least got a nice Squalicorax as shown in the pics below. Since school has started, I've been down in Austin. I've been finding the usual stuff, but the pyritized disk I've attached is new to me. I'd love to hear what you guys think! Austin Finds: Pictured above is the pyritized disk and a pyritized clam found in a gravel bar next to what I believe to be an Ozan exposure. The area has a decent amount of the pyritized clams and other marine fossils that I assume are cretaceous in age given the local geology. My initial reaction was that it could be a vertebrae, but the bulging center and distorted shape throws me off. It has very apparent concentric rings on both its faces. In pics 1 and 3, you can see that underneath that outside layer there is a lot of pyrite. Parts of the edges are also pyritized while other sections have an iron concretion look to them. The face shown on pic 2 resembles and feels like petrified wood. I suppose this could be a pyrite sun, but I'm not seeing anything too similar to what I have on google images. Super interested in what you guys have to say! Texoma Tooth (left) and NSR Tooth (right) Left (Leptostyrax macrorhiza?): Pretty tooth found by my little brother at Texoma in the Duck Creek Formation. Did some quick googling and found that Leptostyrax macrorhiza was in that formation and saw some pictures that were similar to what I have. Right (Squalicorax): Had a bit of a slow day at the NSR, but managed to at least find this at the end of my cold, muddy adventure there. It's preserved very nicely. Looks like Squalicorax to me. Would love to know the species. If you guys would like any additional closeup pics feel free to let me know! I might share some of my other finds later on, but I don't want to inundate the forum with my rocks lol. Thanks for reading.

Hi What are people's thoughts on these three small verts from Hell Creek. The one on the right of picture 2 has rounded ends--if I am not wrong, that is a sign of it being a crocodile? Any thoughts on the other two? I can get extra info from the seller if needs be Cheers

Hi everyone! I'm helping a friend go through a large amount of Cretaceous Moroccan stuff and came across this piece. It measures 6.3 x 6.5 x 4.33 inches (16 x 16.5 x 11 cm). I know it's the process of a huge vertebrae, but I'm not entirely sure from what. I'm thinking sauropod but I was hoping to get a second opinion. Any feedback is appreciated as always!

Hey everyone! My boyfriend and I go shark tooth hunting on the south end of Amelia Island, Florida frequently. Today we went to a new area. Close to a dredging site. I think we found a few fossils! They are all vertebrae of some sort. believe one to be a shark, one a fish, and the other 2, I am stumped on. Any help is greatly appreciated!

I was recently given this amazing fossil from an old man before he passed away. While he couldn’t remember exactly where it was found, he did tell me a general area in Wyoming that is known for Eocene fossils. Any help with identification is greatly appreciated!

Hi Help with ID please. My wife found this yesterday whilst we were walking the Holderness Coast. It’s mainly Boulder clay with lots of erratics but there is some Pleistocene material that gets washed up very now and then. Not sure if it’s modern tho. Thanks

Good evening, these vertebrae are announced as spinosaurid, but it's posible to know just with the centrum preserved? At Kem Kem beds there are a lot of other reptiles so, it's posible to know with incomplete material like these?

Anyone familiar enough with the Crocodylomorphs from the Hell Creek Formation to be able to help in determining a probable genus or species? I purchased this specimen and have been unable to find images or research papers with similar examples.

I usually don't post the trip to POC anymore but this time there were some oddities i wanted to confirm and or see if anyone knows what they are. I found the usual few ptychodus teeth as well as tons of broken shark teeth but also some more rare items. There is one small shark vertebrae, a piece of a fish vert, two broken ends of sawfish rostral teeth, a weird piece that looks like coral to me but also looks like it has teeth poking out of it, a large piece of mammoth enamel, and what I believe is a small mosasaur tooth. Pictures 2, 3, and 4 are the mosasaur tooth. I have it in my hand for scale and it is small but it looks exactly like ones i have seen posted from the North Sulphur River just smaller than most. Pictures 5 and 6 are of the coral looking thing. I could have sworn i saw something like this on the forum before but i have looked and can't find the post. Any ideas of what this is? 1 2 3 4 5 6 7 8

Hi everyone! I just acquired some fossils from Florida and could use some help identifying these two vertebrae. The first I believe is thoracic and the second is an atlas, but I'm not sure what animal they're from. Cetacean was the first thing that came to mind but I all the pictures I've been finding are different looking especially the pictures of whale atlas vertebrae so I could really use another opinion.

Unknown Moroccan Dinosaur Vertebrae
fossil_lover_2277 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I’m possibly looking at purchasing this pair of Moroccan vertebrae. They’re real as far as I can tell from the pics. They’re labeled as “dinosaur”, but that’s as much information as the seller has. Are these even dinosaur? Can anyone provide any other information? Thanks.
-
So I just bought this puppy at Fernbank Museum in Georgia (USA) and it was labeled Mosasaur which I am 100% sure is wrong. Looks nothing like my other one haha. I'm thinking shark? I need help my friends! Thank you.

Found this in Alabama mountains near Huntsville. Was in a washed out area of rock. A professor at Ohio State did confirm its bone and possibly a vertebra. Any one have any insight as to what would have vertebrae this large?
