Hi there everyone! I recently came across a listing for what is described as a partial Edmontosaurus toe bone and I thought it would be a unique addition to my collection. The specimen’s description says it was found in the Hell Creek Formation of Montana which is pretty commonplace with this seller, but I attempted to get in contact with the seller to try and get more information about the fossil (exact locality, how they IDd the specimen, etc.) and they unfortunately never responded. I was wondering if any of y’all would give it a look and give some of your own opinions. I’d love to see what y’all think about it! Also once again, thank you all for all of the help, you guys are awesome!

Another day, another art project for school I’m working on. This time it’s supposed to be inspired by google doodles, so I chose to do the 19th century paleontologist Joseph Leidy. He’s lesser known than his student, Cope, but his finds contributed hugely to North American paleontology. My first concept was to simply have him standing with a Troodon to the left, but that was quickly scrapped. I then went with some light thumbnail sketches, and found one I liked before starting to do an inked version of it. This ended up being the more finalized thumbnail sketch of the piece. He is seen brushing away the dirt on a Troodon bone, with a Troodon watching, and a herd of Edmontosaurus watching the oncoming rain clouds in the far background. I then cut a piece of matboard to size to fit the assignment and started drawing the composition. I’m using an opaque watercolor for this piece. A quick photo to check value issues. The Edmontosaurus in the foreground is simply blocked in here, I have not started actual work on it, which it why it remains so dark and blocky. Pretty quickly I could see the mountains were much too dark, and the rain is much too light. The grass in the foreground is much too light as well. I had 20 minutes to fix things before class ended, so I went with repainting the sky, as well as the mountains. I’ll have to touch this up. I’ll also have to repaint the Edmontosaurus in the background. size on this piece is I think 12 x 30”. I am also doing another Troodon in ceramic clay, which will be fired at a later date in a kiln. Pretty sure my classmates are confused why I’m doing dinosaurs in a pottery class.

Greetings, I have a bone fragment that's a mystery to me. This fragment is part of a find that I had posted in another thread in 2019 showing a Dental Battery. The dentary was presumed to be Edmontosaurus. The pictures here are of a 5" fragment that I would like to identify the bone & placement, this fragment also has a penetrating bite. The sediment that filled the bite area has been removed and the cavity seen in the pictures is from the bite. Two curved teeth about 4" or more penetrated completely through, pushing a lower tooth down into bone while two smaller teeth were sheared away. I've been unable to match this fragment with the other pieces I recovered and any assistance would be greatly appreciated. I found this on private land with permission. Rosebud County Montana.

I had found this online and I have been thinking about buying it. It doesn't look really like an ungual though, and the price seems too good to be true. It says that it is a foot claw from a duckbill dinosaur from the Hell Creek formation of Battle Co. South Dakota. Here are the pictures that the seller had provided. Thanks for any help.

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.

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 fill the space.

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 them, reassembled into proper positions and finally repaired the gaps to strengthen it. Now, I've dug and prepped lots of fossils over the last 12 years, but all have come from sites someone else found. They did the leg work and established the quarry, I just dug in it. Nobody knew this was there until I found it. Im still hopeful theres more of the animal scattered behind it. An Ed. vert centrum washed out from a few feet away. Hopefully I'll get the chance to check the site again. Just a side comment... I hate prepping this type of fossil. I glued and consolidated this as I uncovered it, which also glues all the matrix in place. That helps prevent the fossil from collapsing into gravel en route home, but then I have to dissolve the glue and completely disassemble all the broken chunks, then pray I can put everything back where it belongs. anatomy and taphonomy. Every fossil tells a story and the following is my attempt at reading that tale. I found a great PDF article https://archives.palarch.nl/inde.../jvp/article/view/447/439 specifically about the pes of hadrosaurines. It would appear my fossil is the distal end of Metatarsal III, likely left side. The erosional break was at the point where MT-II and MT-IV were located, and the bone was pointing distally into the matrix, so no other metatarsal bones would have been remaining if deposited in articulation. Phalanges III was not found on excavation, although it is possible to still be in situ and just more separated than the distance I examined. However, the likely reality is that this indicates a disarticulated and isolated element. The measurement on the width is 160mm which would make it an adult, although not at the largest size. The fossil has a high degree of fracturing which is likely due to a combination of freeze/thaw cycles and plant root invasion. Beyond this, the fossil still has a mostly intact surface which says that it did not suffer long term surface weathering or osteophageous beetle predation. The in-situ damage was confined to the highest points, which shows it possibly suffered peri-depositional damage. The matrix was a loosely consolidated mudstone without associated gravels or stone inclusions, indicating a low energy environment such as a delta, marsh, or low flow river. Walter Stein believes the layer to be a continuation of a densely fossiliferous, multi-taxic bone bed discovered about 1/4 mile away. The fossil as I started prepping. After clearing off the matrix. distal end proximal end prepped and repaired

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 staring intently at the ground for float and possibly something sticking out of a wall. Eventually we worked our way down into a draw and found an ironstone layer. Closer inspection revealed a large amount of fossil material. There were bits of turtle shell, croc scutes and small bone bits all throughout. The only complete bone was this distal caudal vert my son found. The sight was thus named "Mitchells Micro Site". We bagged a selection for further study, marked the location and continued on. From the draw, we worked our way up to the main butte. Another pair was investigating the east side, so we began working the west side. Only a few minutes later I spotted a small sun faded bit of float. I began looking up the slope and saw another, and another. As I climbed the side it was obvious that I was on a hot trail, and then I found it, a bone sticking out of the wall, just below the surface. Sadly, the only thing left was about the last 8 inches of the bone (like Edmontosaur), and its full of root rot so the prep is going to be ugly. Just around the corner I followed more float down the slope and found an Ed vert centrum in the wash. The processes are gone, but surprisingly the broken edge seen in the pic, was laying on the surface up-slope, so its reattached and the prep has begun. Walter's team found a large surface exposure, about half a mile away and determined that my Ed finds, and another team's finds were all the same horizon of large multitaxic bone bed. My son ended up finding a nannotyranus tooth in the large exposure site, the only tooth found there that day. And then a call came across the radio "we've got 11 vertebrae in the wall and they just keep popping out". Of course, everyone went to check it out! It appears to be a juvenile Ed. with caudal verts exposed so far, but Walter is hopeful the most of it is still in the ground. Even though it was already late in the afternoon, I'm sure we would have stayed on the site much longer but a wicked looking storm was building fast and moving our way. So the race was on to recover what was exposed so far and get out while the getting was good. We barely got out too. As soon as we got to the pavement, I could see a lowering coming down from the storm, and it wasnt much longer someone said they could see it sucking dirt up. The last place I want to be during a tornado is in the middle of the prairie and stuck in bentonite. So that was the end of the first day. We headed back to town tired, sweaty, but ecstatic after an incredibly successful day.

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 to our hotel in Belle Fouche so I stopped at my prep person to pick up some finished bones from previous trips. A juvenile (still big) jaw its about 22 inches long (55cm) Collected in 2019 , covid delayed preparation A rare baby jaw a bit smaller than the baby one I found in 2019. This one collected in Sept 2020. About 11.5 inches long (30 cm) A nice jugal 13 inches wide I've posted pictures of the site several times and can be seen on my other trip reports in September and June so I will pass on this report.. We constantly get visitors, lots of snakes in Sept but none this time of the year. This group of yearlings were very interested in what's was going on Baby Toads? were everywhere this year My best find of the trip and pretty cool is what I believe is a Troodontid metatarsal IV. I showed Walter Stein and he agreed and had two in his collection which were a match. It also compared well with the New Mexico's Troodontid Talos. It was not found in the Edmontosaurus bonebed deposit but a Lag deposit that sits on top of it. Very brittle bones and nothing is complete in this layer. Its around 6" long. My most unusual find of the trip is this bone. The wide end is 6" across. Our guess was that it's a pathologic toe bone. I shared the photos with Pete Larsen and he said "weird" but one of the possibilities is digit III phalanx 1 toe bone. Have to clean it up to see if it tells us any more. My largest find is this juvenile tibia, 34" long. I don't like big bones but it was ideal to collect and a keeper. I found it during my Sept 2020 trip and prepared the exposed end to handle the winter. Looked great so proceeded to extract it. Undercutting bone, pedestal to be able to apply plaster cast Plaster jacket using burlap and wood stick Flipped - all good ready to go home

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.

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 with it being Edmonotosaurus, or is there another species it could be that I've overlooked? Also, I am curious about the white patch. Is that a sign of restoration, or just some type of weird weathering? Thanks

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 daily basis. The area in Montana is very remote no phone or internet The badlands where we collect in South Dakota The most beautiful critter that we see everywhere on these sites and all over the west is the Pronghorn. At this time of the year we typically see a small herd with a bull and his harem. For those of you not familiar with a Pronghorn its the fastest animal in the western hemisphere able to achieve speeds in excess of 50 mph (80 km/h) Mule deer are ever present and very dangerous if you are driving when dark The site is located on edge of cliff and over the years lots of holes and cavities have been created by erosion creating a wonderful winter den area for the local snakes. So during our fall trip its not uncommon to have visitors slither by us and of course wishing us good luck by waving their tongue Here are some we have seen this season: The only dangerous one is the Prairie Rattler but they typically are not interested in bothering us. You just have to watch where you are walking. Being from Arizona its normal... The Western Ribbon Snake The Yellow belly Racer The Prairie Bullsnake We do have more cuties' Tiger Salamander after a rainfall On to collecting Other than a pick and shovel these are the tools I use 90% of the time to collect I use two glues, Paleobond field prep and stabilizer. The latter on teeth and when I need a very strong deep bond. Harder to prep with PB002 so its only used when needed. For wrapping the bones Heavy duty aluminum foil does the trick where minimal support is needed . Where additional support is needed on large bones we use burlap and plaster. However plaster cloth like the one in the photo works most of the time and is a heck easier to use than burlap
