Hello everyone, I'm new to the group and very excited. I live on our ranch in northeast Wyoming and find many fossils. This one is one of the better ones I have found. Pictures are from the first find to now after some work. Hoping someone can help ID Fossil.

Hello everybody, I'm sorry for making thread about ID mixed fossil types,but I didn't want to open multiple threads for such a small specimens as they aren't something ''special'',but small specimens that I would like to properly ID. They were bought from one small fossil shop that sells fossils,meteorites,amber,dinosaur teeth and those kind of things. They are fairly small shop,but they have nice collection of small affordable fossils for sale. I bought them years ago and I always wanted to get proper ID of them,but my camera wasn't good at the time and I always had more ''important'' things to do. Today I finally got time and I took photos,but unfortunately I forgot where did some of those fossils came from as too much time has passed. I remember some of them,but not all. All of those fossils were cheap. Fossils are placed near metric ruler for size reference and are measured in centimeters. First fossil is Spinosaurus Aegypticus (Cretaceous Period 90 MYO) found in Kem-Kem basin Taouz Morocco It is 4cm long. I would like to know is it possible that tooth from Spinosaurus is sold that cheap and is authentic as well since it's rare animal? I know they had lot of teeth during their life that were constantly replaced by new ones as the animal ate/broke them,but I still having hard time to believe that authentic dinosaur tooth is sold for so little. Second fossil is trilobite that is from Cambrian period if I remember correctly.I forgot location where it came from unfortunately. It's only one centimeter long and I'm not sure if it's authentic or not because bottom of it look somewhat weird (at least to me). I uploaded 3 pictures of it. Third fossil is Neuropteris seed fern Carboniferous period (320 MYO) from Crock Hey pit-Wigan Lancashire UK I uploaded 3 pictures of it and I would like to know do you think it's genuine? Next two fossils are supposed to belong to Tyrannosaurus Rex,but they are so small it's impossible to tell from what dinosaur they came from,if they even belonged to a dinosaur. It's stated that they are from Tyrannosaurus Rex Cretaceous period (65 MYO) Hell Creek formation Northwest South Dakota-USA As far as I can tell (and I don't even belong to newbie amateur class) they seems to have honeycomb like structure that could be where the blood vessels were once the animal was alive. If it's a dinosaur I presume it would belong to some Theropod because of that honeycomb like structure,but that just my humble inexperienced opinion. I uploaded 5 pictures of those two fragments and I would very much like to know did it belong to some Theropod or at least a dinosaur and do they look like they really came from Hell Creek formation judging by color and things like that? Note: 4th T-Rex fragment picture have one side completely yellow that is totally different from rest of the specimen.Do you perhaps know what that is? And lastly,last two bone fragments are stated as ''Triceratops'' bone fragments,but I'm aware that's impossible to tell just like ''T-Rex'' fragment from above because they are simply too small. However,I would like your opinion about them as well. Do they look like fragments that belonged to dinosaur at least? They came from either Montana or North Dakota and I think they are too from Hell Creek formation like ''T-Rex'' fragments,but I'm not 100% sure,more like 90%. They are of course 65 MYO,at least that's what seller stated. I uploaded 7 pictures of those 2 fragments. Once again,I want to apologize for multiple different specimens in one thread,but I think you'll agree that this is better than opening 5-6 threads for such a small specimens. Lastly,I want to thank you for taking time to read this and I hope you can tell me are all those fossils genuine and if those 4 fragments came from some dinosaur if you can get any info from small fragments like those of course. If you have any questions that could help you get better ID,feel free to ask them. Thanks!

I found this in glen rose, Texas at Dinosaur Valley State Park. Looks like it might be a clam or shell of some sort. Anyone have any idea if it's anything or maybe its just wishful thinking.

Hello everyone, I need to provide me Xmas wishlist, and off course it had to involve Dinosaurs lol Do you have some good Dinosaur book recommendations? Mostly looking for images and found locations, and some scientific facts. Not all text Looking forward to what you guys recommend! Best wishes

While prospecting for gold in Placerville, California on Weber Creek in a deep hole I found two eggs a dino bone fragment, which I sold to a local store and a seed grinding tool. The store owner also sold dino poop that he found in the area. Once I presented the eggs to him he pulls out a spray bottle of water lightly misted the eggs and said they were tacky. He said thats a sign of calcium. He still didnt know what species they were. The eggs easily fit in my hand. Is there anyone who can help with the possible I'd of these eggs? Thank you for your time.

Hi everybody! This my dinosaur collection. This is my Hell Creek and Judith River shelf. It's a bit empty but I'm working on getting more fossils. I also have a replica Triceratops skull that I had 3-d printed. This is my tyrannosaur tooth fragment from the Hell Creek fm of Harding County SD. I'd gotten a bag of micro-matrix from hell creek and I got some ossified tendon fragments A partial Pachycephalosaurus? caudal vertebra from Harding County SD A jaw fragment from an indeterminate hadrosaur from the Judith River fm of Hill County Montana And an Edmontosaurus spitter tooth from the Lance fm of WY And now onto the Moroccan fossils I have a spinosaur tooth and some mosasaur teeth, the biggest of the mosasaur teeth being 2 inches. A Spinosaur indet. too

Found this at a fossil selling website. Hadrosaur vertebra. Info: Hadrosaurus Upper Cretaceous (Campanian) 83-72 myo Alberta, Canada.

I am not sure where it was found because it was given to but I'm sure its a tooth because it isn't a rock and it isn't wood.

Please help identify this fossil. Some type of vertebra I believe. Thank you for your time! Tom

I have a couple dinosaur bones that I'm not quite sure what they are. The first one is a vertebra from the Hell Creek Formation of Harding County, WY. The seller had said that it was probably either Thescelosaurus or Pachycephalosaurus. I had been wondering if any further identification was possible. The second one is from the Judith River Formation of Hill County, Montana. The seller had listed it as Hadrosaur indet. Would that be able to be narrowed down to a genus? Also, does anyone know what part of the jaw it is from? Thanks!

Hello, I’m new to this site. I found this fossil in my backyard. Is it a claw or bone? thank you for your help in advance !!!! Emilie

I am a university student studying T. rex, so of course, I ran into the Nanotyrannus debate. People have been arguing about Nanotyrannus being valid, but there's a huge problem: No adult specimen. Unless someone has an adult, or even a subadult, specimen of Nanotyrannus (over 15 years old), it isn't a real genus. This is why I am here. I know people collect fossils and post pics of them on here, so I'm willing to see what people may, or may not, have. My question is: Does anybody have an adult Nanotyrannus specimen? In simpler terms, does anybody have a Nanotyrannus femur larger than 70 cm ("Jane's" and "Petey's" are over 70 cm)? Or a tibia about 90 cm or larger ("Jane's" and "Petey's" are 80-something cm, from what I've seen)? A fibula would work too. I'm willing to give the pro-Nano side a chance here. I'm in contact with a couple of paleontologists, some on the pro-Nano side and some on the anti-Nano side, and if anybody has any hind limb bones of a supposed Nano, then may I please see a pic of it? This is the only way you can prove that Nano exists. Teeth and hand claws will not cut it. As far as I'm concerned, all Nano teeth and hand claws are juvenile T. rex teeth, and T. rex claws. I'm asking for hindlimb bones only. Skull bones would do fine as well. Try to prove that tooth loss does not occur in T. rex ontogeny by providing pics of a maxilla or dentary. NO teeth, only a dentary or a maxilla. I'm not expecting anybody to give me anything of substance, but I wanted to give this a shot to see if I would be proven wrong. I'm being harsh because, if Nano exists, then there should be an adult specimen. All specimens are juveniles, no questions asked. Therefore, the genus does not exist. The only adult specimens of any tyrannosaurid that coexisted with Nano is T. rex, therefore Nano is a juvenile. It's just that simple. Prove me wrong though. Let me reiterate: Pics of femurs, tibias (even fibulas), maxillas, and dentaries, are what I'm after. If we can get a cross-section of a Nano femur, or tibia, and get an age estimate of 17 or older, or has extensive Haversian remodeling, then I'll believe that the genus exists, along with the majority of other paleontologists. Let's see how this goes!

Happy almost Halloween! Show us the scariest thing that has ever happened to one of your fossils or something about fossils that is related to halloween. Mine is this. I'd bought a fake mosasaur jaw but I didn't know it was fake. I'd put it in the sink to clean it off and then the whole thing crumbled. I did get some mosasaur teeth out of it though.

Why are there so many late Cretaceous dinosaur fossil bearing formations in the western usa? In just Montana alone, there is the Hell Creek fm, the Lance fm, the Judith River fm and the Two Medicine fm. The fauna in these different formations are also similar, it's kind of confusing.

Is this Spinosaurus tooth real? I am slightly suspicious of it, but am not experienced enough to tell

Found in the Judith river formation along the milk river. They seem to be a few claws, but unsure about the dark one that’s super hollow as well as the first one that seems to be a bit more uniquely shaped than I’m used to finding. I thought croc claw at first based off what we were finding in the area - but who knows. All three are about an inch long. thanks for the help. Deciding if they’d be worth restoring or not. sorry for the slight mix and match on the photo order

What is this inclusion in this amber? It appears to be some sort of head, but I don’t know what it is

This bone is from Yunnan of China. Is it a vertebral bone of dinosaur or a marine reptile?

I posted in the fossil prep a few days ago about some Judith River matrix I got with teeth. Well now that I practiced on a damaged tooth shard I decided to start on this piece which seems to have two teeth laying on top of each other. I was hoping to get some help on what species these could be. I believe there is an ankylosaur tooth in good condition under the tooth that is more exposed. The small one is about a quarter inch and the larger underneath about 0.6 inches. this material is new to me and I have more matrix with different teeth so any other input is also helpful.

I recently purchased a Theropoda indet. tooth from the Lourinhã Formation of Lourinhã, Portugal. I wasn't expecting much initially since it looked like an incomplete tooth and the seller tends to go the safe route with their IDs if it's too vague. But, the serration count was similar to that of the Marshosaurus-like megalosaurid teeth based on @Troodon's guide on the dinosaurs of Portugal. Maybe it's just wishful thinking, but I wanted to see if anyone else had some input before I slap that good old theropoda indet. label on the display. The distal serrations is split down the middle. Mesial serrations were kind of hard to count, but they are at least 20/5mm, the distal serrations are 16/5mm. Not sure if the split serrations are messing with the count, but it should be around that 16/5mm after counting it multiple times with various pictures. I don't know how much further the tooth would have gone had it been complete, but I think the mesial serrations do appear to end before reaching the base. Although I don't know if those serration densities still overlap with other theropods like Allosaurus. Split distal serrations and shape of the base which could be slightly off due to the split serration. Distal serrations. Mesial serrations. Mesial serrations ending? Close up on denticle shape on distal side.

I recently acquired some matrix with teeth from the Denver gem and fossil show this year. I’m unsure what is best to do. Leave everything in the rock, get the teeth out and see if I can find other fossils as well, or just prep the teeth out a little and leave them in the matrix. I have prepped a lot of Moroccan phosphate material but never something from the states. Also if anyone can help I.d any teeth that would be helpful. Here are a few of them.

Hello everyone. I'm not at all up on fossils, though I do sometimes turn them up while fieldwalking for stone tools in the Lincolnshire Wolds. Normally I just find belemnites, ammonites and other shellfish but today I found this piece at a field edge not far from Horncastle. I've put "dinosaur" and "fish" in the tags purely because I had to put something. I'd love to know what this is and would be delighted if anyone can identify it. Here it is at the moment of finding and after a gentle wash. Thanks in advance, Ted.

Soo I've been digging and finding bone in different areas along w buried deep charcoal and or black thin stone. Most rocks I let sit on a shelf but this one has been bugging me and has me stumped and YES I LICKED IT gross and it was slightly sticky. I've honestly not a clue and the pattern on parts of it has truly just thrown me for a loop. Any help appreciated. USA/VA
