Just sharing some more fossils I had the pleasure of getting identified. Again, from Northeast Nebraska, found in a creek that runs through both the Valentine and Ash Hollow formations. While there, I had the privilege of working at a fossil site absolutely FULL of complete teleoceras skeletons, and was able to ID the femur cap with help from the paleontologist there- the little articulated lip was the perfect match. I attached a photo of the femur another species of teleoceras (the only photo I could find of one) so you can see the comparison. The rib matched the thickness and shape of the rhino ribs there and has appropriate mineralization for its age. Let me know what you think!

Hello all! Like my other finds, this was found in northeastern Nebraska in a creek that runs through both the valentine and ash hollow formations, which are Miocene, as well as some Pleistocene rock. I’m stumped on this one- some animals pieces I’ve found in the creek include bison, rhino, tortoise, horse…but the modern cow gets thrown in there a lot. This is fairly mineralized… anyone have any idea?

White River Bandlands micro-snails from Nebraska
MarcoSr posted a topic in Partners in Paleontology - Member Contributions to Science
I just donated hundreds of micro-snails (most 2 to 3 mm) from the White River Badlands, that I picked from anthill matrix from my sons' M&M Ranch in Nebraska, to the Delaware Museum of Natural History. A group picture of the micro-snails: Some individual pictures of the micro-snails: A figure from Benton Terry Jr. Evanoff McDonald 2015 The White River Badlands Geology and Paleontology which identifies most of these micro-snails: Marco Sr.

Hello!! Just wanted to share with the forum some of my fossils and bones that I do not need identified but would love thoughts on nonetheless. The elephant bone is of a four tusker- the upper part of the tibia, and completely mineralized, and very heavy. It is anywhere from 13-15 myo. The tortoise shell frags include the lip of the shell, as well as a nice slab of the plastron- found separately, but in the same creek. Tortoises were in Nebraska 8-15 mya. The horse tibia has been identified as either the tibia of the small three-toed horse Pseudhipparion, or the one toed horse Protohippus. All of these were found in Nebraska in a creek that runs through the Valentine and Ash Hollow Formations, both Miocene exposures. Let me know your thoughts!!

Hello all, this bone has given me a fair amount of trouble. Several identification attempts have come up relatively fruitless- my running idea is likely an elk. Again, where I found this cuts through early Miocene exposures up to modern day- this bone is mineralized enough to be late Miocene, but I could be very mistaken. What puzzles me is the hole in the middle, which appears to be an invertebrate burrow? I’m unsure of any invert that would possess the ability or desire to burrow into the severed toe of this animal, as it offers not much at all. Let me know your thoughts. Thanks!

Hello all. First of many IDs I will be requesting of the fossils I have found in the Verdigris Creek of Northeastern Nebraska. This creek runs through the Valentine Formation which is roughly dated to 15 million years old, but is also known to cut through Pleistocene exposures. This bone I found has almost certainly been gnawed on- it matched up to the size of one of the larger stem hipparions found around here, but I am still unsure whether it could possibly be camelid or anything else. Let me know your thoughts!! Thank you.

Serious, experienced replies, please! This 0.5 cm long object is attached to a broken coprolite from the Eocene/Oligocene of NW Nebraska. Trying hard to figure it out. Wrong twexture for a tooth and it doesn't look like a seed, either. I have a guess, but right now a guess is all I have. Any coprolite specialists out there? I know the pictures could be better, but I don't have a microscope out here in the field.

Can anyone ID this ball joint? It was found in SE Nebraska. It looks old to me, and it feels like heavy rock. The golf ball is for size comparison. Any help would be great!

I was in the badlands of nebraska in May and found a half turtle, dug it out and brought it home. However I did not pack it well enough to survive Fed Ex it was bounced hard enough to crack the internal mud into multiple pieces. I am now trying my ability on a 3d turtle puzzle. I multiple pieces yet to place, but I have one piece that I have not idea where it belongs. It is a little different. After I removed the turtle from its resting place in nebraska, I looked around the extraction site and the immediate area for anything I missed. this piece is from that final harvest. IIs it a piece of skull or just an odd looking piece of the edge of the shell, or something else again. All help is appreciated

Greetings, all! After exploring outcrops and spoils piles from Quebec down to Florida, we are heading west from Delaware to Crawford, Nebraska and back this fall. Planning to stop by Sylvania, OH and Clear Lake, IA. Probably Richmond, IN. Any other suggestions? Thoughts on these three?
-
Any ideas on who this belong to? I’m pretty sure this is fossilized but not 100%. Area is almost entirely Miocene.

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.

OK gang, this one has me stumped. This is the last specimen from last year's final trip to the Kiewitz shale, Stoner Limestone, Stanton formation along the Platte River in Cass County Nebraska. I thought at the time, and until a few hours ago, that this was one of the disc shaped oncolites that have been found at that site and related sites in the area. I was playing with a recently LED upgraded microscope and found it had cellular structure barely visible. so I decided to do a laborious prep on it with a bicarb blast. It is in fact nothing I have ever seen before and is very fragile. Frustratingly, when I stabilized the fragile little thing, it made the structure less visible. So, I had to get creative as I realized too late all my scope cameras and adapters are sitting on my desk at work... Anyway, I have no clue what this is. the simplest solution is a disc shaped bryozoan, but the more I worked on identifying it, the less convinced it is within my skill level to identify. So, here we go:

Found in north central Nebraska. Miocene. I’ve had this in my collection for a while, I don’t know why I overlooked getting it identified. Really a nice little specimen.

Ok gang, been a while since I posted some fossils. I’ve been practicing my prep work and trying to get around 2500 specimens organized in my personal collection in addition to the Uni’s collection and a dozen other projects! Brachiopods are a weakness when it comes to ID. These are specimens from the last 17 years, some have my old labels and such. Unless Otherwise Noted all have the following location data: Sarpy and Cass County, Nebraska, USA Kiewitz Shale Stoner Limestone Stanton Formation #1 some sort of productid

Mystery critter -Kiewitz Shale- SOLVED brachial valves still working on genus
LabRatKing posted a topic in Fossil ID
Finding a complete specimen is my white whale. Usually only find small fragments, these three are my most complete. Am able to use a few bits to get a “reconstruction” cannot figure out what these are. thanks in advance!

All from Nebraska. I thought the last astragalus was Mesohippus at first, but it seems much flatter than the other Mesohippus ones I have. Any and all help is much appreciated.

I need help identifying this fossil, or eliminating possibilities. I found this while searching for Native American artifacts and other fossils. It was in a stream. Found in North East Nebraska. Geologic research says the area it was found is within the Ogallala formation from the Tertiary Period. Several members of a FB group think I might have a fossil fungi and have asked for samples,, which I am reluctant to attempt to chip off myself. Several of the photos show signs of fungi. I know that fossilized mushrooms are extremely rare in the fossil record, usually only being found encased in amber, and never in physical form. Thanks.

Managed to get out of my cage for a bit today and went to the only publicly accessible site near me.

One of my finds from the Nebraska badlands found circa 1960's.

I find these all the time and write them off as just more crinoid parts. The locals bring me tooth-like crinoid parts all the time. This ain’ no Petalodus I’m familiar with... Stanton Formation However, a student brought me this one today... I have about a half dozen at home. Is this a “shark tooth” or crinoid parts?
-
These are from Nebraska. Since it’s not oreodont, I’m lost. Do people find coprolite in this formation?
-
I wasn’t even going to post this one up but it does have some unique features so I thought I would give it a shot. Any guesses?
-
No idea what this is from but it is in really nice shape and completely fossilized. North central Nebraska. Miocene

Not sure if this is the right thread, but, here is a bunch of specimens. All are resin or plaster casts of the real deal. some appear to have been painted (poorly) none have been stored correctly and any records of them are long gone. These are part of the collection at the University I work for. I'm not a mammal guy, but I suspect I had better become one quickly. Some have various collection codes on them, but I have been unable to figure out what they mean. These are some of the ones I am clueless on: Jokingly referred to as the "bonenana"...tusk? rib?
