Edmontosaurus annectens Hell Creek Fm., Harding Co., SD, USA Partial dental battery Hadrosaurs had the most histologically complex teeth of any animal, with six unique tissues. This allowed for differential wear, creating an ideal coarse surface for grinding plant matter. (Erickson et al. (2012)) -
I'd gotten an Edmontosaurus caudal vertebra from @Troodon and had decided to prepare it a bit. I had used water to soften the matrix and a metal pick. Here are the before and after pictures. Before And after Also, does anyone have any tips on how to prepare hell creek fm fossils because I just wet the matrix and basically scooped it out.

It's Fossil Friday, so I have another fossil video ready. This is a prep of the Edmontosaurus neural arch I recovered in the video posted last week. A little background: Edmontosaurus Annectins, 66 millions years old (Maastrichtian) of the Hell Creek formation, Butte county, South Dakota. Recovered while digging with Paleo Adventures

So I got this bone chunk that came in a bag that just said Edmontosaurus Bone from Hell Creek Formation. It looks like it might be an identifiable bone. Just wondering if it's identifiable or just chunkosaur. Here are the pictures.

I'm collecting Hell Creek Dino teeth and this is in the new collection: rooted Edmontosaurus tooth. The tooth measures almost 2 inches and has a evidence of repair at the middle but still looks great. Since it is diamond shaped I guess this is a dentary tooth. And this is current progress of my Hell Creek Collection. I have two Tyrannosaur (Nanotyrannus, if you think it is a valid genus), a Ceratopsian, and a Edmontosaurus. The lower right corner is still empty. I have an Nodosaur tooth but it is too small to

Hell Creek vertebra, caudal vertebra from a Edmontosaurus?
Georgemckenzie posted a topic in Fossil ID
Hello everyone I purchased this hell creek vertebrae as I’ve not got much dinosaur material from there,(from the uk) just wanted to make sure the sellers ID is correct, locality is Powder River, Montana, Hell Creek Formation -
The title says it all. It’s a nice tooth, but I’m going back and forth on it because the telltale wear patterns for either group are not present as far as I can see. I apologize for the poor quality of my camera phone picture.

I just returned from a dig near Baker, Montana. I found this part of an Edmontosaurus jaw with the teeth replaced by siderite. I thought it was a rare replacement. If important, the KT boundary was very visible on this ranch. The section is about 3 inches by 3 inches.

Finished my latest prep. Now, I realize that in the worlds of both commercial and academic paleo, this is a useless, junk fossil. Its an unassociated, partial in poor condition, and any final monetary value doesnt meet the time invested in the prep. However, its special for me in that its my first "wild" find. I hiked, explored, tracked the float, found the end of this in the face of a wall, then excavated it. I was hoping for a much more complete fossil, but this was it. It is highly fractured and deeply root rotted. But I carefully disassembled all its parts, cleaned them, consolidated t

I have what I'm pretty sure is a triceratops hoof, but I've come to understand edmontosaurus and triceratops hooves are hard to tell apart. It's from the hell creek formation, Montana. It's 3.5 inches across and long

What a trip my son and I had this year! We started out in the Hell Creek fm of South Dakota. This was a special trip through Paleo Adventures for his "veteran" guests who have already spent a few years with him and could operate without supervision. We started out hunting a new ranch. This property is virgin ground with LOTS of acreage that needed exploration. The group was split into 3 teams, each taking a different area. Our team was further split into pairs. So, it was my son and me, exploring for new outcrops. The sun was intense, the temperature hot, and hours of hiking and sta

Just returned from collecting trip to my usual Edmontosaurus bonebed site in South Dakota. It was one of the worst weather trips over the years I've been collecting with daily AIR temps between 90 to 102 degrees F and winds typically in the 25 mph range and some days gusts hit 40mph. Temps on the bluff were much higher and the winds limited our use of tents so we were constantly blasted with sand and sun. The good news was no rain so despite the hardships one could collect. We targeted getting to the site by 6am and gave up around 2pm. I pass through Hill City, SD to get

Edmontosaurus Astragalus from Hell Creek, South Dakota
TeethCollector posted a topic in Member Collections
I want to share a nice Astragalus of an Edmontosaurus, from Tooth Draw Quarry, Hell Creek Formation, South Dakota. According to the shape of the fossil, I guess this is from left leg of the Edmontosaurus.- 1 reply

Hello, This fossil caught my eye as one to buy. It is described as a radius--23 inches long. Seller doesn't know the species, but speculates it could be theropod. Am I right in thinking it is actually Edmontosaurus? It is from Hell Creek, Montana -- near the town of Jordan. I did a bit of looking, and 23 inches seems far too big for any of the Hell Creek theropods. Edmontosaurus radius bones look around the same length--a google search shows some previously sold which were around 20 inches plus. The weight is just under 6lbs. So, am I correct

Hi everyone, I recently bought this 'Triceratops' vert from Hell Creek online. But on receiving it, I have doubts. I might consider it to be an Edmontosaurus vert. It is not that heart shaped and thicker than a Ceratopsian I figure. What are your thoughts? Dimensions: 12,5cm (h), 9cm (w), 7cm (d) - weight +/- 700 grams More pics needed? Thank you!

The virus put a damper on my Spring dinosaur collecting trip but I was able to get a partial one in for the Fall. I was able to spend several days at my usual Edmontosaurs bonebed but unfortunately only one day at a channel deposit in Montana where theropod/mammal material can be found. Hopefully next year will be more normal, Hopefully. Quite a few new members since my last trip so I will get into more specifics to get them a view of how I collect this material. First let me share with you a view of the collecting area and the LOCAL wildlife that we deal with on a

I finally finished a shadowbox display for some of my Edmontosaurus fossils. The top 2 are a proximal and distal sections of dorsal ribs. Both found a few inches apart, but are probably not the same actual rib. Bottom right is a small rib head section my son found 10 years ago. Its either a juvenile rib head or an adult cervical rib. Bottom left is an ossified tail tendon and the only complete one I've found (or even seen found). You typically only find 1" - 2" long bits and never the vertebral connection. I find it rather funny how much time was spent cleaning, repairing and prepp

I recently got this rather nice Edmontosaurus annectens braincase from the Lance formation. But what's interesting, it has this large hole in the top of the skull. The seller has told me that the hole is not the result of any collecting or prep damage. The seller found the piece themselves and apparently it was found upside down in the field. I've bought from this seller before and they always have high quality fossils so I'm inclined to believe the seller when they say that this hole is old damage. So then my first thought would then be, could this be a big tooth mark? Although I don't w

Identification of Some Hadrosaur Teeth from North America
Troodon posted a topic in Questions & Answers
Although identification of Hadrosaurid teeth in North America is very difficult or impossible some older publications by John Horner give us some information to help us with a few. The information goes back a bit so there might be some new understanding but will share what is published. If anyone has publications that can add to the dentary information of teeth from North America please feel free to post it. Horner notes that on dentary teeth all Saurolophinae teeth have diamond-shaped crown whereas Lambeosaurinae teeth are more elongate see figure 13.4. So one may not be able- 1 reply

So, this is a labor of love I am attempting (probably poorly) to rebuild. Its a caudal (tail) vert from an Edmontosaurus from the SD hell creek formation. Highly fractured when recovered, and suffering from extreme root rot. Completely missing a "V" shaped portion of the anterior portion of the centrum, probably about 1/5 of the total. Surprisingly I do have the neural spine intact, just have to replace it after I finish reconstructing and filling the centrum. Also included a pic (and my guide) for what it should look like.

Here are some of the better finds from my digging trip in South Dakota last year. First up is what is likely an osteoderm from Ankylosaurus. This specimen is gone for research. I've got a "stupid rookie" story to go along with this if anyone is interested. Next is a section of Edmontosaurus rib with the head and part of the main. This still needs final cleaning and consolidation. I'm still debating whether to leave them separate or re-create the missing portion and join them. This is the largest and most complete ossified Edmontosaurus tail tendon
