I donated thousands of specimens that I collected from anthills on my sons’ M&M Ranch (mostly Oligocene but there are a few Eocene 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:- 84 replies

I am looking for confirmation of the identity of this rodent jaw from the White River Group of NW Nebraska. I am thinking Ischyromys. Thoughts? Scale is mm. Occlusal view enlarged and not to scale. @jpc, @Fruitbat, @Nimravis

Hello All, I am hoping someone might be able to tell me what this is, or what it was a part of. A LONG time ago we were traveling the country, we stopped in Nebraska and Kansas and use to backpack everywhere. We found this in the sand one day after a hard rain the night before. We took it home, as we didn't really know what it was. We are thinking it is a fossil of some sort. So the item was found in the north west section of Nebraska. Was found in 1993 and sat in a safe since. I pray someone may be able to shed light on it.

I collected thousands of micro Squamate (lizards, legless lizards and snakes) specimens from anthill matrix from my sons’ Eocene/Oligocene, White River Group, M&M Ranch in Nebraska in 2016 and 2017 that I donated to the Smithsonian Institution. I spent over 3,000 hours over a year and a half picking the specimens from the anthill matrix. All of the squamate specimens have been with a squamate researcher in Germany since late 2017/early 2018. Unfortunately Covid and two other major projects that the researcher was working on, a major Messel Pit publication and a climate paper, delayed th

By some vast, cosmic alignment of karma, snolly has become the possessor of a horde of material, deaccessioned from a museum's abundance. Information is scant, but "Oligocene" and "Nebraska" are offered as clues. The foil wrapped specimens had apparently lain in benign neglect for a a generous span, the bone rests in pieces with sheets of dried, peeling consolidant and crumbling matrix. The specimens appear to be limb bones and Oreodont is the donor that presents as likely. At present, snolly is leisurely joining the puzzle pieces and removing old consolidant (white glue?) and mat

@Harry Pristis identified one of these for me not too long ago. Could I possibly be lucky enough to have found another one? This one is quite a bit smaller than the last one, but still a big tooth! L-32. W-23.

First one of these I have found. Need a little help with ID please. L-23 W-12 H-20.

Ok I thought I had started to be able to ID bovine teeth and jaws and then this threw my off. This is from a post on Facebook - found in a cave in Kansas. I have posed here with he user's permission. Why is there a three-lobed molar in the middle of this lower jaw? In the past I had though the m3 for cow/bison was the only three lobed molar. But some searching online is telling me otherwise. Also the m3 here looks two-lobed. Can someone clarify?

No idea what this is from but it is in really nice shape and completely fossilized. North central Nebraska. Miocene

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 t

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.

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 rh

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?

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 thou

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:- 1 reply

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.

My younger son Mel just led his first fossil trip of the year on our Oligocene M&M Ranch in Nebraska last week. My sons, Mel and Marco Jr., are starting to get back from their prepper some of the fossils that they found on our ranch in 2018. Not all fossils go to the prepper. Mel preps some of the specimens himself. Below is a picture of the specimens Mel found in 2018 that he will prep. Here are a few pictures of 2018 specimens just back from the prepper.

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!

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?

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

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

Any ideas on who this belong to? I’m pretty sure this is fossilized but not 100%. Area is almost entirely Miocene.

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 be

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.
