Seller lists this as a Pachycephalosaurus toe bone from Hell Creek formation, South Dakota. It is 1" long x 7/8" wide. That is all the information the seller gives. I have no clue how to ID a Pachy toe so i figured it was a good one to put on the forum and get help from more knowledgeable collectors

Recently found this bone on an auction site for a reasonable price. Decided to buy it since it looked a lot like a dinosaur maxilla. It arrived today, unfortunately, I don't see tooth sockets but still have no idea what else could it be other than a maxilla. Likely dinosaur (it lacks sutures typical for croc skulls) and maybe theropod (very porous, thin and light). I know it might be hard to identify, but even suggestions on the location of the bone in the skeleton will be very helpful! Location is Hell Creek formation, Montana, it is 6" in length @Troodon @LordTrilobite

I really really love primitive birds and would love to see your primitive bird fossils, with scale if possible I only got a couple myself but would love your opinions!

Hello everybody So we have this rooted tooth here: This tooth was found in Carter County, Montana / Hell Creek Formation and labled as Ankylosaurus magniventris. I just wonder if this ID is correct. Unfortunately I can't provide other pictures. I am aware of Troodons great post CLICK but still struggle with this tooth. This might be a worn tooth, but can't really see the key points Troodon pointed out in his post. Thank you for the help

I have recently acquired a nice Richardoestesia tooth from Hell Creek. I suppose it's R. isosceles. I decided to read more about this species, and felt really confused. Why is it even considered a dromaeosaur?? As far as I know, dromaeosaur teeth are not only usually smaller and strongly distally recurved, but also have no or very fine serrations on the mesial side and coarse serrations on the distal side. Richardoestesia teeth I've seen lack all of these characteristics: they have identical very fine serrations, straight and relatively large crowns. Actually, such teeth remind me a of land crocodylians, such as Sebecus from the Cenozoic, however Richardoestesia teeth are somewhat more labio-lingually compressed.

Hey everyone! If someone could post a pic of what a HC champsosaur tooth looks like that would be appreciated. I have not found one yet (I thought I did a while ago but they turned out to be from Melvius) but I am interested to see what they really look like as most of what I see online look like fish teeth or crocodile teeth. Thanks, Noel

I bought this claw a little while ago, for close to nothing. Still waiting for the item to arrive. Not sure what it is from though. It was dug up in Hell Creek. The claw and bone measure about an inch in length in total. Anyone who would have a qualified guess?

A totally AWESOME addition to our dinosaur collection
fossilsonwheels posted a topic in Member Collections
I recently added a Dromaeosaurid vertebra to our collection. I honestly did not bother with specs once I got it confirmed as Dromaeosaurid. I never asked size or what formation. I assumed it was from Judith River because it was sold as Dromaeosaurus. i knew it was going to be Dromaeosaurid indet so I was not worried about the specific ID. It is a raptor fossil so I wanted it. The vertebra arrived today and I got two very pleasant surprises. It is bigger than I thought. It is also not from Judith River or the species known from that formation. We got a Dromaeosaurid vertebra from the Hell Creek formation Many of our fossils end up being listed as a indet species. This one went into our official inventory as Dromaeosaurid indet. An indet species gives us some degree of latitude with our programs. I assign species to many of them such as Medusaceratops or Zuul from Judith River so that we can teach the kids dinosaurs they do not know about. When I first saw Hell Creek on the paperwork, I thought "Great, we have a vert to add to our Acheroraptor display which contains a single tooth." I began to think that I should assume it is from Acheroraptor because I had run across a published paper about a reconstruction of Dakotaraptor's tail. I thought it might be a good idea to reread that paper and see what information it provided. Our caudal vert is 5 cm long. Much to my surprise, that is right in the middle of the size range for a Dakotaraptor caudal vertebra according to the reconstruction (if I read the paper right). Now I am not saying this is a Dakotaraptor vertebra. I am nowhere near qualified to make that call. I also doubt I am lucky enough to find a fossil of that species by total accident lol I am also not qualified to say for sure that this is not a Dakotaraptor fossil. As an educator, this gives me a really awesome option. I am now considering that this may be an opportunity to add Dakotaraptor to our program with a fossil that MAY be from the giant raptor. Kids would dig that and it gives us the chance to talk about how the science, and art, of describing dinosaurs works. I think I am going to to print up the paper and give kids the information from it. They can see the fossil and come to their own conclusions. We do this with the lineage of Great White sharks. We show the kids teeth from a GW, a Meg, and a Hastalis. They can make their own conclusions though 80% of the kids the other day believed hastalis is the ancestor of the GW. It was a fun thing to do and it would work very well this fossil too. Dakotaraptor has been high on my list to add but I thought it would be down the road. I do not think there is any problem with introducing this fossil as possibly being from Dakotaraptor. Either way, we added an really cool fossil that I am super stoked about. Here is our Hell Creek Dromaeosaurid indet vert. Is it Acheroraptor or Dakotaraptor ? I am going to let the kids decide which awesome raptor this fossil is from.

i have found quite a few micro jaws from the hell creek in the past like lizard and fish jaws, however i recently went through some old finds and noticed a small jaw, and i have absolutely no idea what it might be. it doesnt look like fish or lizard to me. the length of the jaw is about 14mm.

I need some ID help/education. I saw a few vertebra for sale and they are in my price range so I thought I would put them on the forum and gather some more informed opinions about these. First up is a "Raptor" vertebra from Hell Creek. It is around .8" x.5" inches. I lack the skills to determine if it is dinosaurian let alone raptor but my gut says likely not.

Hi All, I'm looking for some help to try and better ID this bone I collected on a Hell Creek Microsite last Summer. This was only an isolated bone and as you can see isn't complete. The length of the bone is just under 10" and the width is 4" at it's narrow point. It's a fairly flat bone with curved-edges on both sides. It's also hollow as you'll see from the photos of the end. The owner of the ranch said it had a very similar pitting on the surface to other t-rex bones they'd found on the site. This microsite produces plenty of T-rex, Nano, Hadrosaur and Triceratops material. It might of course be impossible to ID due to it's incomplete nature. It is however a pretty large chunk of bone so there are only a few bones that it could be. I was thinking it could be part of a theropod scapula due to the flat near-rectangular shape of this. Any thoughts? Tom

Hell Creek Theropods help wanted
Mesozoic Mike posted a topic in Is It Real? How to Recognize Fossil Fabrications
Howdy folks I'm still building my collection of Hell Creek fossils. This time I'm attempting to add three new specimens, that of Anzu Wyliei, Dakotaraptor, and a Troodon. I would be very grateful to get your opinion on the following fossils. The raptor teeth are labeled as "Dromeosaur Tooth" from Hell Creek I want to know if any of them look like Dakotaraptor teeth to you. As for the other two I simply want your opinion on whether or not they are genuine fossils. Thank you Anzu claw measures approx. 15/16″ long Raptor Teeth 1 2 3 Toodon measures approx. 1/8″ Thanks again

I just saw this tooth listed as Dakotaraptor. It's 3/4" long. Most of these "Dakotaraptor" teeth I see just scream Nanotyrannus, but I'm not so sure on this one. I looked at my Acheroraptor and Nanotyrannus teeth and the distal serrations look a bit more like those of Acheroraptor - especially those near the base. Unfortunately, the mesial serrations are all worn off. What do you guys think?

One of my goals is to bring a very tactile element to our education programs. I think adding a piece of dino armor is going to be a real hit with the kids. I have been trying to brush up on ankylosaur and nodosaur scutes in preparation of getting one at some point in the near future. I am not to the level of being able to recognize them yet but I did see one in our price range. I am not sure about this one. The seller lists it as being from Hell Creek. It is 2.5"x1.5" and is 1/2 inch thick. Anybody have any thoughts about this one ?

A few months ago we purchased a T-Rex tooth from TFF member @Troodon and he also gave us a super nice Nano tooth. I never got his permission to mention that sale or the gift so I get that anonymous. That is our only T-Rex material and it was also the first fossil donation to our program from a Fossil Forum member. Those teeth really helped us get started becasue it allowed us to use our small budget to fill in other parts of the dinosaur program around having T-Rex stuff. We owe him a huge thank you for that and I wanted to share this on the forum. Well we now have another gigantic THANK YOU to give Frank. I arrived home from work yesterday to find a package from him and it was beautiful dinosaur fossils and some additional non dinosaur Hell Creek material. There were some fantastic fossils in that box and he helped us really strengthen not only the Hell Creek part of dino program but also our African dinosaur section as well. I say this in most of our posts now because it is true. We could not do what we are doing without the support of The Fossil Forum and the members here. @Troodon shares his knowledge and his identification skills with everybody here and that has been invaluable to me. Our dinosaur program is heavily influenced by the knowledge I have gotten from him and bolstered by his generous donations. Thank you Troodon and all of TFF members who donate fossils, share the knowledge and offer encouragement. We really could not do this without you The box o' dinos..... Thescelosaurus fossils (toe bone, vert, two teeth), a beautiful Ceratopsian tooth from HC, an Edmontosaurus tendon, some awesome HC croc teeth, an R.isosceles tooth, a really nice Spino tooth, an abelisaurid tooth,a beautiful Titanosaur indet tooth, and a Ornithomimid toe bone (possibly a juvie Struthiomimus).

I saw this for sale and this would be perfect for our program if they are dinosaur bones. I am not well versed in bones yet and some of these look very interesting. The bone in the lower left of the picture and the larger one to the right of that both caught my eye. I do not know what they are and I did look at some pictures before I posted it but I could find much in the way of help for myself so I thought I would put it to the forum. If they are dino bones, this would be a nice addition so if you have a thought on what these might be, please share ??

I have several large fossils that have me stumped. I am a florida boy, I can rattle off almost every fossil you can find here....but.... These are found in a storage locker 15 years ago in San Diego, Ca. There is no info on location collected, I am guessing hell creek formation. Any direction, advice or thoughts would be greatly appreciated. The three images are from the 1st of 18 fossils. It is 92 lbs, 22 inches long, 12 inches high and 12 inches wide. This one is the only one sprayed, not sure

Looking for a little help identifying this Hell Creek vertebra I purchased a few years ago. I bought it off an individual with lots of experience hunting in Hell Creek, but unfortunately he had no idea what it might be from. Any help would be much appreciated!

Hell Creek vertebra ID help- maybe a theropd caudal vertebra ??
fossilsonwheels posted a topic in Fossil ID
When I first set out to collect Dinosaur fossils, a fossil dealer with a long history in the industry and from whom I had purchased shark fossils from had this listed for sale. It was sold as a Troodon formosus ( I am aware it is an invalid taxon). When I committed to purchasing this, i was unaware that only Troodontid teeth had been found in Hell Creek and I tended to believe dealer ID's. I do not regret the purchase. It is a great little bone to have in our education program and it was not expensive. We want to cover Troodontids in our education program which is why I bought this. It was cheaper than a tooth. It was also a good lesson to learn early on and without a significant financial investment. I do my homework know before purchasing a dinosaur fossil and if I have questions, I put it here. It seems unlikely that that the dealer ID is correct just based on the lack of Troodontid bones that come from Hell Creek. I want to know we have and be accurate in what we present to kids so I have put some effort into figuring this out. It is a very small vertebra as you can see in the pictures. I did find some small theropod caudal vertebrae that look similar including a Troodontid. I have done some homework on this and tried to figure it out but I can not get much further on my own. All I can say for sure is that is does not appear to be a fish or mammal and I do not think it is a crocodilian either. Any thoughts or information would be helpful !!

Based on the numerous and informative posts of @Troodon, I feel pretty confident that this tooth is an Acheroraptor. It is from the Hell Creek formation, South Dakota. I saw some things that looked diagnostic and the seller provided pics that were pretty good. Anybody want to confirm the ID or present an alternative ?

Our First Trade on TFF, our Acheroraptor tooth arrived, and Zuul
fossilsonwheels posted a topic in Member Collections
We had an awesome item show up in our mail box today, an Edmontosaurus jaw fragment. It is the product of our first trade on TFF and it is really the first dinosaur piece we have that is not a tooth. We traded an extra dinosaur tooth for it. A Hell Creek for Hell Creek swap. Thank you @Captcrunch227 for an awesome trade and for being a great trade partner. We are super happy with the process and the end result. The mail brought another pleasant surprise. Our Acheroraptor tooth arrived. It is a beautiful tooth and a great addition. As if our day was not busy enough, we secured ourselves an Ankylosaurus tooth from Judith River and it is not a nodosaur. Right tooth from the right formation. I am not saying it is a tooth from Zuul at all but it gives us a chance to tell the kiddos that it MIGHT be . I think Zuul is the perfect species to discuss armored dinos that a lot of kids will recognize but also I am super fired about it. All and all, a pretty fantastic day off from work for me lol

I started collecting dinosaur fossils fairly recently and so far I have a pretty good working idea of what I have. There is one exception and I thought I would share on the Fossil Forum and see how far I can get with an ID. My guess is that it I will not get much further then unidentified theropod but it could be something completely I suppose. It does not really look like the Acheroraptor tooth I have and it is larger. It does not look like a Tyrannosaurus of any kind to me either. I will work on getting better pictures up though I did get some detailed shots of the serrations on the micro eye at work. This is my first attempt at really assessing a tooth so my language and/or wording may be not be correct. Call it the learning curve lol This is what I know It is from Hell Creek, Powder County Montana Slightly over 1/2 inch long This is what I observed Serrations are larger on one side than the other and extend further on one side. The denticles look a bit rounded to me and seem very uniform but are really quite small. I counted 5-6 per mm but I had a hard time counting them and am probably wrong lol I THINK it might be a Dromaeosaurid but I am calling it unidentified theropod for now. If you know your dino teeth and feel like giving an opinion, I would love the input. I may not know what it is but I do know that is a pretty nice tooth to have. The serrations are in great shape even though they are small and the tip is worn but not broken. I got it at a reasonable price to so regardless of what it is, I am pretty stoked !

I found a tooth here online and it claims to be a Raptor tooth from Hell Creek. It has a classic Kem Kem color and kinda looks like a croc tooth?
