Hello all, Looking for help in identification of this fossil, looks like a toe, but from what. Was found in south central Nebraska loose on a river bank. There is some 4x4 traffic through the area so I suspect driven over and freshly broken. Sucks but it in interesting to see the interior of the fossil. TX, Jim

Hi everyone. Found this forum and gotta say - I LOVE IT! I just started learning how to hunt last summer. Anyways, I was gonna be in northwestern nebraska this weekend, and have been looking for places to fossil hunt. One place I saw was the badlands go into the northern part of nebraska near ashfall (which I guess you CANNOT collect it). I've been looking for a publically accesssible place to go to where it is allowed. Does anyone know a place they can recommend? I'm thinking just that general quadrant of the state or so for some mammal fossils. Thanks

Not only do I not know which critter this came from but I also I don’t know which bone it is. Getting a proboscidean or rhino feel. Any help appreciated. Most likely Miocene, found in North Central Nebraska.
-
Pretty sure this is a tooth. What do you guys think? North Central Nebraska, Miocene. @Harry Pristis @Shellseeker
-
I think these are all pisiform bones but I’m not 100% sure. @Harry Pristis, I looked at some of your older posts about these bones but the shapes didn’t seem to match these. first one measures 68 mm x 54 mm. Second one measures 52 mm x 43 mm. The last one is 44 mm x 34 mm
-
Any ideas on this one? Should be Miocene like the rest of the stuff in my area. Nice little well preserved bone. Found in North Central Nebraska.
-
This is the smallest one of these I have ever seen. Any ideas of what critter it may have belonged to? Found in North Central Nebraska Measures 20mm X 12mm.

It was along a fence line 6inches down. Previous owner had coral rocks up front. It is pretty solid and heavier than it looks. It's not magnetic nor does muriatic acid effect it. I don't want to use a sledgehammer. Any opinions? THANKS

Hi all, seeking some identification help from those familiar with marine vertebrates from the Pennsylvanian black shales (Nebraska, Missouri, etc.) I recently obtained a few ex. Ted White and Bill Rushlau specimens of Romerodus orodontus and a few very nice Iniopteryx rushlaui and one unidentified specimen was included. Just for context for some reading this, W.D. "Ted" White and Bill Rashlau were very prolific collectors of the Pennsylvanian black shales, primarily the states of Nebraska, Missouri and Iowa. The specimens that they collected and cataloged are in many museum collections. The Iniopterygiformes were named as a new order by Zangrel and Case, 1973, with the type species Iniopteryx rushlaui named after Bill Rushlau. Ted White was a recipient of the The Paleontological Societies Harrell L. Strimple Award, which recognizes outstanding achievement in paleontology by an amateur. Gerard Case also received this award in 1992. Location: Hansen Quarry, Papillion, Nebraska. Stark Shale, Pennsylvanian T. White collection notes: Sat., April 5th 1947. Spec. # 8284. "Shark - unknown sp. A 20 x 40 cm. mass of rough textured tissue. up to 7 mm thick in one area. No shagreen observed. General features this is a probable anterior fragment suggesting an individual approx. 1.5 meters in length. 50 or more distinctive teeth unlike any previously found in these shales. These teeth range in length from 5 to 10 mm. unlike the fairly common Cladodus tooth, these have a roughly triangular shape and have only 1 crown or cusp. About 40 of the teeth are partially separated from the mass and are more or less in a normal orientation. A circular 2.5 cm in diameter defined by some more calcified parts may be an orbit or the symphysial whorl." I do not see any features that point to elasmobranch, but the remains do more resemble some of the "blown out" shark remains I have seen from the Penn. black shales. The teeth, which are pretty distinctive, do not resemble anything I can turn up. I also considered that they may be dermal denticles, but the arrangement does not make sense nor can not find any Pennsylvanian aged denticles that match. The "teeth" indeed measure up to 10mm in length, as described in White's collection notes. I am hoping some of the forum members familiar with marine vertebrates from the Penn. black shales can help. Pic of full specimen (teeth circled in red), pic of area with teeth, and a close up of some of the more complete teeth.

Going on road-trip starting in Ohio and headed west. Looking for fossils
KMiller posted a topic in Fossil Hunting Trips
We are taking our camper from Ohio to the west and will be stopping in Nebraska and the Black hills. Can anyone suggest a place we can hunt dinosaur fossils and keep what we find? We can pay, but not much. We would also love to hunt for arrowheads. Also looking for somewhere to help a team that are digging. We are both ill and this will be our last chance. Thank you so much.

Not a true fossil hunting trip, but a hunt for an identification. In July last year, a saw a listing on online auction site for a fossil "shark/fish". I do not often make purchases on auction sites, as quite frankly I never see anything really cool, but I do look from time to time as I suspect many of us do. Something about the specimen caught my attention, but I was not certain based on the poor pics or info from the seller what the specimen was. I did email and asked some questions, with the response, "I bought it from an estate sale and have no idea what it is". I kept watching for a week - no bidders. I then did something unusual for me, I bid at the last min (I was the only bidder) and won. I just knew there was something cool about the specimen. I received the package and thought, it certainly looks very sharky, but unsure of an ID, I put it in the back of a display case thinking I would figure it out at some latter date. Fast forward to 2 weeks ago: a friend of mine sent me some pictures of disarticulated Pennsylvanian shark remains from MO in black shale, including pelvic fins and other remains. I was wracking my brain and going thru my reference material, but was having a tough time putting IDs on some of the material. I then remembered my copy of Case's, "A Pictorial Guide to Fossils" had some good images of Penn. sharks. I was flipping thru and wow - page 230, a near complete specimen of Cobelodus aculeatus = an exact match for the specimen I purchased in July! I had in my prior collection a few ex Case specimens, and have had him help me ID a few specimens many years ago. I was totally shocked, I had an ID and a near complete shark from Nebraska, and one published by Case. Even better was the cost !!! Image of my specimen and image from page 230, Case, "A Pictorial Guide to Fossils": Cobelodus aculeatus (Cope). An essentially complete shark in ventral position in black sheety shale. Wea Shale, Westerville Formation, Kansas City Group, Missouri Series (Westphalian D), Papillion, Sarpy County, Nebraska.

Recently for Christmas, I received the marvelous gift of a bunch on different unprepared fossils from an unknown location in Nebraska (Purchased of the auction site). The first piece I started was a smallish jaw from an oreodont that I think turned out ok. I still plan to clean up the teeth a bit, but I'm not sure what to do next, as this is the first time I've prepared anything other than Green River fish. I'm considering removing it from the matrix entirely, but I'm concerned about the stability of the fossil, as the matrix is quite crumbly and the back has been consolidated by whoever found it, along with aesthetics. Any advice as to what to do next would be appreciated (Or if anyone knows what it is more than an Oreodont)! Thanks! Dimensions of the jaw are 14cm by 6cm, or about 2.3in by 5.5in. Unprepared After a few hours of using hand tools and my Dremel Current state: Front Back

This may be the best preserved Horse tooth I’ve ever found. It has very little wear and even still has the roots! I’ve looked through all the reference material that I have available and really haven’t found anything close. Even if I don’t get an ID I knew Jack would love to see this one! L=20.5mm W=13mm H=29mm. @Shellseeker

Hi, Recently I received several unprepared fossils from Nebraska, although the exact location is unknown. One of these fossils I have been preparing is a lower jaws from an unknown animal and I would like to know what it is, and if possible an idea of the time period and/or formation. Any help would be appreciated. I currently think that is probably a lower right jaw from the oreodont Merycoidodont. The dimensions of the jaw are 6cm by 14cm, and I am happy to post more photos if necessary. Thanks!

I donated thousands of specimens that I collected from anthills on my sons’ M&M Ranch (mostly upper Eocene but also a few Oligocene small areas) in Nebraska to the Smithsonian and to the South Dakota School of Mines and Technology Museum of Geology. There are currently six researchers studying the specimens with multiple papers in progress. Covid-19 slowed the progress down significantly but it looks like a few of the papers are now starting to move forward. Below is a link to one of my TFF posts that shows a few of the micro specimens that I collected and donated: http://www.thefossilforum.com/index.php?/topic/66138-oligocene-micros-from-the-mm-ranch-in-nebraska/&tab=comments#comment-692680 Below is a link to a TFF post that shows macro specimens that are also found on the M&M ranch. The specimens shown in this post were not part of my donations. http://www.thefossilforum.com/index.php?/topic/94904-mm-ranch-in-nebraska/& The first paper that will get published (in writing right now) describes mammals (insectivores) from the M&M Ranch. Below is a preliminary illustration of what families/genera/species were found on the ranch. I was really happy that there was a new species of Oligoryctes and a new genus of Soricidae (shrews). However, the specimens provided further scientific value as summarized in the below e-mail statements by the insectivore researcher: “The effort was definitely worth it. Even for some of the already known species, the specimens in this collection preserve parts of the animal not seen in previously described specimens and there are also quite a few range extensions (both in terms of age and geography). And this is just the “insectivores,” I am sure the other portions of the fauna will also be informative and provide many new discoveries” The numbers in parentheses represent the number of specimens. You can see that for some of the species there were a very large number of specimens like H. fugax where there were 501 specimens. When the paper is published I’ll add a link to this post. Other papers that will eventually be published will describe Squamates (snakes, lizards and legless lizards), Amphibians (frogs and salamanders), Mammals (rodents) and eggshells from the M&M Ranch.

I recently got this skull as a fun prep project. I bought it as a Hyaenodon skull from North Western Nebraska. But I quickly noticed that it was likely something else. I don't have a whole lot of experience with carnivorans but I think it might be a nimravid based on the number and placement of the teeth. Hoplophoneus or Dinictis maybe? It's missing its fangs and all the front teeth but otherwise it's in general good shape. I've already removed a whole lot of material. And it's starting to look like something. There is very little crushing and the bone is quite well preserved. But there is a break in the middle of the skull. So I fear some bone might not be in the best shape under the matrix there. Fossil as arrived with a bunch of matrix on it. Especially the left side had a lot of material on it and seems a little better preserved than the right side. After the first big prep session. And the most recent state with again a whole lot of material removed. It seems that sadly the jugal isn't as intact as I had hoped.

Thankyou ahead of time! This could be nothing as i am an amateur in most perspectives but on my normal dog walk/ rockhounding adventure i picked up something different, half buried, but uncovered in some new trails made by some heavy equipment here in south east nebraska. Will add several photos, im not sure of anything except i know its not a rock im familiar with! Thankyou again for any information!

Hi, Looking for some confirmation on these vertebrae. Found below a eroding layer of Pierre shale. Thinking Mosasaur but the two lower "wings" seem odd. Also in the last pictures you can see the thin layer of orange matrix, top of Pierre shale? K-PG Boundary perhaps? Thanks in advance for info and insight.

I thought this might have a good chance of getting identified because of the unusual shape of the tooth sockets. parts of the teeth still remain in the sockets. Found in north of Central Nebraska. Miocene. @Harry Pristis

I had magnanimous offers to join 3 fabulous collecting trips this summer, those being Hell Creek for dinos, Morocco for trilobites, and Nebraska Oligocene badlands hunting. After careful consideration, I chose the latter, for a few reasons. First of all, I had been friends with the other 2 guys, Rob and Greg, since my first Oligocene vert hunt 10 years ago, where my wife and I met them. Our 2012 trip, however, wasn't very fruitful, so a rematch was in order. Greg had some good ranches leased and critical equipment in storage nearby, so a small group of 3 friends made good sense on this trip. I figured this venue might not ever be cheaper nor less hunted in my lifetime. Round trip airfare was a bargain at $365, so away we went. The other guys were delayed by about 10 hours coming from Florida, so I got our rented pickup truck and played tourist solo in Rapid City, SD for the day. I thoroughly enjoyed a visit to the Geology Museum at the SD School of Mines, and found the staff to be quite engaging. It isn't everywhere I can hold an intense, 2 way fossil conversation for an hour, then I have to be the one to end it due to time constraints. Great displays, but I only took one photo (Brontops, a harbinger of things to come), then strategically gift shopped for my wife, filled my belly with buffalo lasagna, and picked up travel weary companions before burning rubber south to Crawford, NE where we weren't settled into our cabin until 2 a.m.

Could use a little help with this one. I think I have it narrowed down to Nannippus but haven’t found a close match with the info I have available. Thanks. APL=24mm. TRW=23mm. MSCH=37mm. Thanks @Shellseeker @Harry Pristis
-
I tried researching this but all I can come up with is that it’s a foot/ankle bone from some mammal. Size is roughly 32 mm x 22 mm x 43 mm. Found in North Central Nebraska most of what I find is mid Miocene. @Harry Pristis
-
Hoping to get this narrowed down a little bit as to what critter this came from. Found in north of Central Nebraska. Miocene. @Harry Pristis @jpc

I can’t tell if this is just a very worn piece of vert or something completely different. Found in north central Nebraska. Miocene. Thanks.
