From the album: Hell Creek / Lance Formations
A remarkable dental battery of the hadrosaurid dinosaur, Edmontosaurus annectens. Hadrosaurs had highly sophisticated teeth arranged in these batteries which advanced teeth in a conveyer-belt fashion to replace worn ones. Even the roots of teeth were used once the enameled crowns wore away. This one was in active use and fossilized when the animal died. This battery in particular is special, as it was collected by former forum member Troodon, seen in his "My Jurassic Park" thread here. It comes from a hadrosaur-dominated bone bed.-

Typical shed hadrosaurid (Edmontosaurus) teeth, a.k.a. "spitters." Most are river tumbled and missing their enamel. These teeth are quite common, as Edmontosaurus was abundant and regularly shed them from its arsenal of hundreds. A) teeth in occlusal view-

During my trip to the Hell creek formation of South Dakota last year, I found this large rib weathering out of a hillside ("cliff side" is a better description). I jacketed what was still in situ, and collected all the surface float at the site, and at the bottom of the cliff it was in. The length in the jacket was 32 inches. Can't determine which species this rib belongs to, most likely from Edmontosaurus or Triceratops, but it will have to remain indeterminant. After removing the excess matrix in the jacket, I discovered that the rib was far more fractured than I thought. Because the rib ended up being pinched by the jacket, I had to remove it in sections instead of a single piece. That worked out for the best anyway, for prepping it in my blast box. I have 40 hours into the removal and gross cleaning of the sections. Another 10 hours and still counting for separating all the breaks and cleaning out all the matrix in between bits so that everything can be reassembled properly. It looks like the rib has a healed fracture, but of course, one of the modern breaks goes through the remodeled bone. The jacketed portion looks to be the main shaft of the rib, only missing a few centimeters of the distal tip, based on the the end has thinned and flattened. The collected float should be the majority of the head, but reconstruction of that will be much harder. I wish I had a cast of a complete rib head to correlate the bits of float to their original position.

This unknown rib was recovered a couple months ago from a private ranch near Faith, SD. I haven't had time to start work on it until a couple days ago. I'm keeping track of my hours on this one just out of curiosity. I never tracked the work on any previous prep projects. So this was found partially exposed with a number of pieces found as float at the bottom of the hill. Everything surface was collected, then the rest of the rib was jacketed to remove. It took me 3 hours to uncover and remove it from the jacket, and then 5 hours separate and clean the pieces of the first section. 12 hours total to clean 3 sections, and then another 3 hours for the micro cleaning and reassembly of those sections. Its only going to get harder, because much of the rest of it looks to be heavily crushed and displaced. It also looks like there is a healed fracture to this rib, but of course, the modern break goes through the remodelled bone.

I am interested in buying this piece of what is advertised as skin. From South Dakota, pretty tiny piece (tape measure in inches). Seller says it is a positive impression, but the grooves are small. My only concern is the color? Is that usual of hadrosaur skin impressions? Im buying on the contract that I can return if it is not how I hoped, but I don’t want the seller to have to ship it only for me to return it so I figured I’d ask first.

Edmontosaurus tooth? (and question about replica Tarbosaurus claw)
Psittacosaur9 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone! I'm going to start posting fossils individually, to gain more traction on the forum. I'll post a few fossils I am worried are fake or composite today, then repost any fossils I have yet to receive identification for with higher-quality images in about a week. I bought this Edmontosaurus tooth fossil from a somewhat unreliable website online. Is it real? If any of you need more high quality photographs, please tell me. Also, as I don't know where else to post this, I purchased this Tarbosaurus claw replica a while ago. Do any of you know which digit it comes from? Thank you and hope you have a good day! -
Hello everyone! I recently acquired the attached fossil as a jaw fragment (with additional bone) of Lambeosaurus lambei. It's supposed to be from the Hell Creek Formation - at any rate, it was found between Jordan and Fort Peck Lake in Montana, and I have no reason to doubt this information. From what I understand, however, L. lambei is a little earlier than Hell Creek and the very existence of lambeosaurs in Hell Creek is a matter of some debate. I've now wondered if there's any obvious reason why this couldn't be a jaw fragment of Edmontosaurus annectens instead. As I'm a complete novice, your insights would be more than welcome. The jaw piece is 21.5 cm (about 8.5 in) long, the bone 26 cm (about 10.2 inch). Thank you very much! Nick

Microfossils are the means by which we can most fully appreciate the diversity of a past ecosystem. From salamanders to Tyrannosaurus, an ancient river captured and preserved dozens of species that lived in Montana 66 million years ago, at the terminus of the time of dinosaurs. In this small collection alone, I count at least 27 species of dinosaur, lizard, crocodile, fish, shark, salamander, turtle, mammal, and mollusk.-

Just purchased this Edmontosaurus ungual and would like to know if it's indeed a toe ungual as advertised or a hand ungual? Considering the small size of 1.75" (length) x 1.5" (wide) is it correct I might assume it's from a juvenile Edmontosaurus? Location: Hell Creek Fm., Powder River Co. Montana

The goal of this project was born by and for people who love dinosaurs and paleoart in general. My purpose is to give people a representation as realistic as possible of what these great extinct creatures were, regardless of the time or work involved. With the funds raised I will publish my first 3d models, a Trex and an Edmontosaurus as an example. of what can be created later.As a photo is worth a thousand words, here you can see the level of detail used to. greetings to all.

Hi all! I am relatively new to the forum as well as to collecting but I have put together a small collection of various specimens over the last year. This collection will keep growing and I will continue to post when I get new specimens. I have some more small specimens but for now I am only posting a selection of my collection. Enjoy! -Ben

Picked up a vert, supposedly found in Montana in Hell Creek formation. It's a little crushed but otherwise intact. Any reason to think it's not Edmontosaurus?

Bought this Edmontosaurus bone during our trip to Colorado. Per the museum staff, they sell bones too damaged to restore. I was thinking it appears to be a first phalanx but it is fairly damaged (whole ?dorsal aspect is missing surface) and I can't be sure.

My Spring trip this year was quite a challenge. Last year we had oppressive heat, it was extremely dry with high winds. This year it was rain, rain and more rain and cool. The ranchers however are in heaven with pastures that are green, green and green. Hopefully it continues for them through the summer. So, we had a few rainout days, lots of drizzle and had to deal with gumbo feet, slippery cliffs and wet bones and matrix. Not the best of conditions for collecting and the group's results showed that. On the downside the day we departed Belle Fouche, where we stay, a very bad storm hit with tennis size hail, 70mph winds and lots of flooding. Unfortunately, there was lots of damage to homes, businesses, vehicles and roadways. Lots of work getting that community back to normal. I'll start with the down days. Visited the BHI to dropoff some specimens. Pete Larsen is currently doing a study on the number of Leptoceratops that exist in the HC formation and wanted to see my maxillae to cast and study. He showed us skull elements that pointed too two distinct species. These are most likely associated since they came from the same deposit. Pete showed us a beautiful replica, that he recently acquired, of Raptorex which is a dubious dinosaur. It's actually a juvie Tarbosaurus. BTW the juvie bones are identical to an adult one. Hmm Trex and Tarbo are very closely related...so does that mean that juvie T rex bones would be similar to that of an adult. A new Stan replica was getting ready to be put together A visit to the Carter County museum is a must on a rainy day Their Anatotitan Dinosaur - actually an old Edmontosaurus Triceratops T rex Nanotyrannus Jane
