Curious about iron and pyrite in the Hell Creek Formation
Maniraptora posted a topic in Questions & Answers
Hey all! When I went on a collecting trip in the Hell Creek Formation in Montana, there were many iron concretions, and I've noticed that some specimens from there appear to be iron-stained. This makes me wonder if pyrite could be among the minerals involved in fossil preservation there. Are some of the bones found in the Hell Creek pyritized, and how could those be distinguished from others preserved differently? If so, do those Hell Creek specimens ever develop "pyrite disease," and what would be the warning signs to look out for? Thanks so much for sharing your knowledge! -
Unfortunately the only information on the fossil is that it is from North America. I was thinking it is a distal femur or proximal tibia but really have no clue. Is it possible to ID the type of dinosaur with just the end of a long bone? Any input would be greatly appreciated.

Looks like a vertebra to me. Anyone know what kind?

Pls help with an ID of this toe bone found in Hill Cnty, MT. I have taken several views of it and it is 2.25" long. It had been exposed for a long time and had a layer of lichens on it. Is it Tyrannosaur related, raptor, or ?? Thanks!

I have this piece of chunkosaur from the Lance Formation. It looks like it might have the trabecular structure of tyrannosaur bone. It's from the Lance formation of Weston County, WY. Thanks for any help.

Hello, here is a bone I found in the JRF about a week ago. It was found in a site with various dinosaur and crocodilian teeth. Thanks for any help. It is 3.875" long.

Hello, I made this find in the Alberta badlands yesterday, the area is known to have tons of hadrosaur bones, so i assume thats what i have. unfortunately, i was not prepared to extract the bone without completely destroying it, so i plan on going back to get it some time this week. I collected many bone fragments from the area, and have noted down the location. I will post decent pictures once and if i am able to bring the fossil home, i seem to have forgotten to take proper pictures in my excitement! I would also like to ask for advice on how to extract this fossil. I plan on pur

Hello, I believe this bone shows evidence of teeth scoring from a predator Dinosaur (raptor or other theropod) and I am asking for a confirmation of this. I found this a few days ago in Wyoming in a formation I believe may be the Lance but I am not sure. Teeth there include Archeroraptor, other Dromeausaurid (sp), triceratops, avaceratops, paralbula, myledaphus, hybodus shark, edmontosaurus, borealasucbus, brachychampsus, fish, a couple of mammal types, large theropods, Aublysodon?, lissodon, Ankylosaurid, melvius as the most commonly found specimens. Of course, none are common but just in com

Are different dinosaur species bones different colors?
creepyspiderlady posted a topic in General Fossil Discussion
There are so many beautifully colored dinosaur bones. Are the different species the reason for the different colors? -
Hi peeps, I just found this at Yaverland Beach, Isle Of Wight, United Kingdom. Wondering if it’s a dinosaur bone?

Recently I was talking to a friend of mine and I was advised that her granddaughter, who I had given some fossils about 6 years ago, when she was 10, was not into them any more. I advised her that if she did not want them, I would take them back. So today we met for dinner and I brought the fossils back home. Here most of the stuff- Eurypterid pieces, I believe from New York. Fish from the Brazil Santana Formation. Cephalopod pieces- Ammonite from South Dakota A clam from S

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.

These are a couple smaller vertebrae and a bone I found on the Judith River Formation, I was hoping to get an opinion on what dinosaur they would be from. Thanks.

I found this bone fragment in East Feliciana Louisiana. It is translucent and looks to be crystalized. Bone width is 1.5 inches (round). Any help would be great and helpful. Thanks

I'd found this dinosaur bone on an online website and it looks like it might have bite marks. It's from the Hell Creek Formation of Harding Co. South Dakota. Here are the pictures.

From the album: Dinosaurs
This is a textbook example of dinosaur bone. Numerous Haversian systems/osteons are visible (which are the circular structures you see). They are actually cylindrical, but we are seeing a cross section here. Osteons are present in all cortical bone, but they are particularly impressive in dinosaurs. https://en.wikipedia.org/wiki/Haversian_canal- 2 comments

I found this in the Judith River formation last weekend near the Milk River, I assumed it was just croc scute but it is thicker and different texture, maybe its turtle or a different kind of croc. @patrickhudson thinks its dinosaur skin but I doubted him.

Well, I figured that I should start a member’s collection. Sorry for my absence, I was busy with college classes. I did great this semester, and I even won a student leadership award! With that being said, I’m gonna start my collection off with a piece that I acquired for my birthday! My 22nd Birthday is tomorrow (June 14th), and I was strapped for money. My father and grandmother chipped in, and helped me acquire this chromium woodworthia piece from a local rock shop that I frequent! It’s from Arizona, and it only cost $60 USD! I’ll try to be active here whenever I can

Ankylosaurus/Nodosaurus Ungals and Foot References?
Kurufossils posted a topic in Questions & Answers
Hi, does anyone have or know where I can view images of a ankyloaurus/nodosaur foot but especially the ungals? Having a hard time finding images for a comparison. -

?Tyrannosaurus rex Lance Fm., Weston Co., WY, USA 1" X 1.5" X .5" I got this bone perhaps foolishly last year (although it wasn't very expensive at all; that coupled with the provenance that follows is why I got it). It was sold as a T. rex bone chunk, like many you can find online. There is nothing identifiable about these hunks of bone - you need something more substantial like a whole bone to be certain. I got this bone from a seller who finds many of the fossils himself, was director of a small museum in South Dakota (now gone I believe), and found T. rex -
Hi y'all. I bought a lot of fragmentary, unidentified dinosaur rib bones from Hell Creek, Harding Co., SD. I didn't buy them for this bone in particular, but once in-hand, it caught my eye and I wondered if it was identifiable since it had a more unique shape. This of course may be wishful thinking, and I'm fine with it remaining unidentifiable. My primary guess is it being the proximal end of a Tyrannosaur cervical rib. I referenced Brochu (2002) "Osteology of Tyrannosaurus rex: Insights from a Nearly Complete Skeleton and High- Resolution Comp

Perhaps someone could shed light on these 2 hollow bones. The little one came in abag of misc bones years ago and has a fused joint ? at end, the big one I just dont remember . The little bone maybe has a faint smell when burnt, not positive. The big one has zero smell when burnt. The big one is heavy, the little one feather light. If someone could suggest species and if dinosaur would be great.

From the album: Aguja Formation
Dinosaurs have a distinct bone structure, with large and well-defined Haversian Systems/Osteons (which look like rings around holes where blood vessels used to be).
