I bought this at a little shop near Deadwood (not the antique store from my other posts) & am curious what part of the body does it come from. The hip? It looks like there are bite marks on it too... I believe the shop owner said it was from an Iguanodon.

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 I have seen. Most of the time you only find little 1 inch sections. This one is completed prep, retaining some of the matrix and a random BOB, as dug. Nice chunk of turtle shell. I have a love/hate relationship with these. This is one is large and quite thick. Most of them are extremely thin and fragile as egg shell. Still needs final prep and consolidation. Unfortunately its a covered in CA, which is making it so much harder. A very nice Tricerotops tooth that my son recovered. He is like a magnet for these large trike teeth. This is the 3rd big one he's found. All I find are tiny spitters. This is a juvenile T-Rex tooth, found beside the Ed rib. This one is gone for research. There's also a small nano-T tooth missing its tip, and a large BOB which I think could be a bit of Trike frill. No pics of those available at this moment. I'll have to add them later.

From the album: Fossil Flourescence
I was playing around with the UV lamp in my lab, seeing what might unexpectedly glow this afternoon. This was a nice surprise. It's an internal mold of Bacculites sp. with sutures that fluoresce orange under 345nm UV light. Bright orange like this usually indicates calcite, a mineral that makes up fossil shells and some modern ones, too. Between the mud-filled chambers, the shell was preserved while the exterior of the cone wore away. The shell material was either calcite to begin with or, more likely, began as aragonite (same chemical compound as calcite, but different crystal structure and glows yellow instead of orange) and changed over millions of years to the more stable configuration of calcite. Meanwhile, the mud looks like it may have a little bit of some fluorescent minerals in the mix, but it's mostly a daylight-only affair. The blue may be some residual glue from a label. This specimen is from the late Cretceaous Pierre Shale Formation in South Dakota.© C. 2020 Heather J M Siple

Here's an interesting fossil I found from the summer which I am just getting around to posting. I believe it's a piece of turtle beak based on its shape and the numerous holes which I believe are part of the vascular structure of the beak, rather than just the standard cancellous tissue of bone. Here's a modern one I found online for comparison. And one from a marine turtle on the Oceans of Kansas website.

I found this bone over the summer in the Hell Creek formation of South Dakota. I have no idea what it could be, and I don't even know if it's complete. It's slightly reminiscent of the ear bones I see on here sometimes, but that's just a guess. The fossil is about a centimeter from top to bottom and around 8 mm wide

Three different people have posted what I think is a very similar if not the same fossil. In my original post I said it was Mississippian. However, I did purchase it from a dealer that described where he found it. I was not there. He was elderly at the time so there could have been confusion. I think he has passed now, so no way to know Let's assume age is unknown. Here are the other postings. https://photos.app.goo.gl/BCMTpriMfuSoaCi79

Hello everyone, I found this nice claw in South Dakota over the summer and have yet to find a definitive match for its identity. It's about a centimeter and a half long.

Here is an Oreodont skull I prepped a few years ago. I did have to glue some of the larger rear skull pieces together, but otherwise there are no restorations. Just sharing with the group.

Can anyone help identify these fossil teeth? One was in a section of matrix from Nebraska and the others came from sections of matrix from the Badlands of South Dakota.

I picked up a little Hell Creek lot that hat this fossilized bone in it. I think it might be a theropod toe bone from looking around on the web at Hell Creek bones. Anyone with more experience (most everyone) have any opinions?
-
Hello, I saw this online. Just curious if it actually is what the label states: Oreodont Braincast / Badlands of South Dakota / Oligocene Period. Thank you for any and all help.

Hello member of TFF. I finally got a chance to really dig (sort of pun intended) into some matrix I bought back in December of 2013 from I believe tj102569 (but it's been so long I cannot find the sale post anymore). If I remember correctly the matrix was from a quarry in possibly Grant county South Dakota. But it was definitely from a quarry in South Dakota (yeah I know there are more than one). The matrix is pretty hard. Engraver and dental pick don't do much more than scratch the stuff. The seller at the time said he used a hammer to just break it open and find sharks teeth. But I was after large and micro fossils so I didn't like that path. I started to use regular 3% peroxide with a small amount of success and combined with the engraver found a few things, but not as well as I would like. So I store the matrix away until I could find a better solution. Flash forward to now in my new prep room and some 12% food grade peroxide and I get results I like. The 12% really breaks down some matrix. Word of warning though I measured temps of 167.4 Fahrenheit so if you chose this method be sure to use containers that are good with cooking temps (old food grade containers are what I use). Anyway low and behold I believe I have found a mandible. But it broke on me as I was picking it up with tweezers. What do you think? And this is the starter matrix. Thanks for your help.

I was hoping some folks on the forum could confirm this ID for me. I found this interesting little piece in the hell creek formation of South Dakota back in July with Paleoprospectors. I was told by one of the guides that it could potentially be a piece of skull armor from a young ankylosaur. I want to know what everyone here thinks.

Hello everyone and thanks in advance for any help or ideas. Earlier this summer my friend moved to South Dakota and purchased a home. A few days ago he was cleaning out a shed on the property and found a cardboard box filled with the fossils seen below. It is unknown if the prior owner had found these on the property or if they had been purchased elsewhere. So unfortunately he has no idea where or when these were originally found. Neither of us have much experience in this but obviously fossils such as these catch your attention! If anyone wants or needs additional pictures let me know and I will see if he can send more. I have included mostly pictures of the skull and teeth as I figured they would likely be most helpful for identification. It is assumed all these pieces belong together but it is possible it is just a random collection. The pictures in order are: skull facing front, skull bottom, skull side (close up), three different angles of the jaw/teeth, and then one pic of all the pieces together with a ruler to get a ballpark idea of sizing. Hope you guys enjoy the pics and hopefully someone out there has some guesses. Thanks!

Hello Everyone, I am facing a bit of a dilemma. Husband is getting me a trip to go dig fossils for my 40th birthday!! Now, the dilemma of choosing where to go! My dream has always been to go to Green River formation for fishes.... however, here locally I am used to finding marine fossils only (North Texas), and another option would be to go with a certain Adventure group in South Dakota for some variety. I love prepping the delicate fishes, and think the Green River experiences would give more to take home with. Anyone here have any experience, or advice? I want TO DO BOTH!! Thanks in advance, Suvi

I have a fossil found in the Hell Creek Formation in South Dakota. Through studying I have not found a bone that matches mine in any known Hell Creek dinosaur. The bone is 8 1/4 inches tall, 5 inches long, and a width of 1 3/4 inches. The fossil weighs 2 lbs and 14.2 ounces. My belief is that it is from an ornithischian, possibly a ceratopsian or an ornithopod. It has a large hole in it for bone marrow, and at first glance looks like a human hip bone. Please help ID my fossil! Thanks!!!! -Carnoraptor

I spent another great day in the Hell Creek formation of South Dakota (w/ Paleoprospectors) and found a lot of great fossils. It was a beautiful day, the temperature wasn't bad at all, helped by the occasional breeze and the bugs were tolerable for the most part. We started the day on a microsite which was eroding out of the side of a hill. The iron siderite pebbles were sharp to sit on and the slope was steep- being sure footed was certainly an asset along a good portion of this exposure. In spite of those factors, I still found some awesome fossils. A view of the microsite from the ground. My first good find of the day- A worn Richardoestesia tooth Most likely a Myledaphus vertebra A Champsosaur vertebra in situ An Amphibian vertebra- probably salamander. Probably my best find of the day- a claw whose identity is currently unknown. Two great anthill finds- Top: likely a marsupial tooth (Alphadon?)- Bottom: a multituberculate tooth (Cimolodon?) After these finds, I went to prospect with some other people but unfortunately came up empty handed. At least I got some pics of the cool looking exposures. After we returned from prospecting I decided to finish the day hunting the microsite where I started and spend some time at a channel deposit below which was also producing some solid finds (Another participant found a nice Acheroraptor tooth and a small theropod or bird claw there earlier) Center left: Myledaphus tooth A nice croc tooth. My last good find was a small section of theropod claw which I unfortunately did not get a pic of. Stay tuned because tomorrow we visit another Hell Creek ranch in North Dakota this time!

I spent the day hunting the badlands of the Hell Creek formation in northwest South Dakota. It was beautiful outside. The sun was shining, the breeze was blowing and the insects were mild. The group started the day working the amber microsite- a spot where a phenomenal amount of amber is produced from lignite rich exposures mixed in with a deposit of smaller fossils. I spent several hours picking up amber bits along with a variety of other fossils. Here are some photos from the first few hours of the day Views of some of the collecting area A shot of the gravel where many of the fossils lie. Some pics of the amber- a small fraction of what I picked up. Several Brachychampsa alligator teeth. Left: A small Edmontosaurus tooth Right: A small digit, potentially turtle or crocodile Left: Small vertebra- amphibian? squamate? Right: Crocodilian osteoderm Left: One of my best Brachychampsa teeth to date Right: Awesome crocodilian tooth I left the amber microsite around noon to go prospecting with some other people, here is a view from atop a butte we found some fossils on. I found this awesome turtle claw after finding some shell pieces eroding from near the top of the butte. Since I found it among many pieces of softshell turtle shell I would assume it's a trionychid. As we moved away from the butte, we explored a dried creek bed which created a small valley with some exposures on the side. We found a few fossils including a champsosaur vertebra another cool claw. It belongs to another species of turtle, although I'm not sure what variety. I returned to the microsite to wrap up the day and was not disappointed by my finds. I found this Paronychodon tooth below the main amber site . My last big find of the day was this cool section of crocodile jaw. I found a ton of great fossils today and I'm crossing my fingers that tomorrow will be just as productive!

I am obtaining this tooth that was collected in 1980s and found originally in S Dakota and is 3 1/2 inches. The person only identified it as dinosaur tooth. Here are the pictures. It looks like Trex right? Thanks in advance.

Went out to the Badlands last week for some fossil hunting. Little bits of turtle shell are a common sight and the folks with me were in turtle fragment city, but this find was a little unusual. Take a look at what is turning into a whole tortoise plastron!

Real Mosasaur Teeth?
UnbrandedMoss posted a topic in Is It Real? How to Recognize Fossil Fabrications
Saw these at a rock shop in Custer and was a bit skeptical what do you guys think? For $9 each?

This small mammal comes from South Dakota. i got it from a collector who didn't know what it was but recalls being told it was from South Dakota. I might have biased people enough with my guess of Insectivore based on my research, so I won't add in any more ideas. Many thanks!

Hello gang, As promised this is where I will share specimens from my personal collection, my grandfather's collection, and the collection that was donated to the university I work for. The latter is interesting as it is literally boxes of rock and fossils, with no information and my university does not have a geology or paleontology department. I'll be updating it every so often. Enjoy! NOTE: Some of the donated items have old school "labels" on them. If you see initials or such that you recognize, please PM me, as I am doing my best to properly catalog them properly as part of my job!
