This was labeled as a Phorusrhacid, possibly Bathornis and was found in the Brule Formation of South Dakota. Is that accurate?

Small jaw segment with teeth (Ischyromys?) White River Formation
Opabinia Blues posted a topic in Fossil ID
Hello, this is a small jaw segment from the White River Formation (Poleslide Member of the Brule) from Weld County, CO. This is one of a few jaw segments I cannot white identify. It does not look like the Leptomeryx jaw segments that I have collected (and indeed is even too small to fit that genus), and the shape of the teeth to me do not look like they belong to an Artiodactyl of any kind, so my best guess based on picture browsing is Ischyromys but I could be very very wrong here so I appreciate any help. Thanks! -
White River Formation small incisors - Rodent? Lagomorph?
Opabinia Blues posted a topic in Fossil ID
Hello! This is a small fossil from the White River Formation of Weld County, Colorado. To me it appears to be a set of front incisors rooted to a small piece of the maxilla or mandible. There are no teeth or tooth sockets next to the two that are there, and so this makes them look like the two incisors characteristic of rodents and lagomorphs. Interested if anyone can tell me anything else about them. Two photos are through a stereo dissecting microscope at 20X magnification, the other two, though blurry, should give a sense of scale. The entire fossil is about 9 mm tall, with the -
Hello, everyone, Lately this summer I’ve been doing a bit of casual fossil collecting (with explicit permission!) on some land that a very close family friend owns in Weld County, Colorado that has a lot of exposure of the White River Formation, and I’ve collected a sizable amount of material including some pretty awesome finds. Being an amateur, I need some help identifying some of the fossils I’ve collected. Since the forum has a photo upload limit per post, I’ll be making a few threads for different finds, I hope that is ok. This small bone appears to be

Archaeotherium upper jaw section
DawnOfADream posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone! Prior to the lockdown and money getting tight I won this at an auction, and it finally arrived today. What are your opinions and observations regarding its authenticity? I was also wondering about the white areas that appear to flow seamlessly with the specimen- is this also a binding product? It did say that it had restoration, and it’s clear that grey plaster/cement has been used, particularly at the front of the jaw where it appears to have previously broken. Thanks in advance! -
My Stylemys nebrascensis tortoise from the Oligocene Brule Formation of Nebraska
MarcoSr posted a topic in Member Collections
I found this tortoise on my sons’ M&M Ranch in Nebraska. It is a Stylemys nebrascensis tortoise from the Oligocene Brule Formation. It is a monster, 23"x17.5"x8" around 150 pounds in weight. It has minimal restoration. I actually found this tortoise in May 2016. You can check out the below TFF post to see it being dug out. http://www.thefossilforum.com/index.php?/topic/65393-oligocene-tortoise-from-the-mm-ranch-in-crawford-nebraska/& Because of the size, our normal prepper wouldn’t originally prep this tortoise. So my sons brought it back to Virgini- 24 replies

While playing with my poo (the fossilized version), I noticed this imprint. It is adjacent to a bone fragment. I'm assuming it is the imprint of a piece that broke away from the bone inclusion. It looks a bit unusual/ornamental, but I am hoping it is recognizable to one of you brilliant bone folks. This is from the Oligocene, Brule Formation, South Dakota. @Carl

I have had a bunch of broken bits of Oligocene mammal coprolites sitting in a cup for years. I got them before I had a proper microscope. I decided to pick through another one last night. This one had what I thought could be a rodent incisor. So I started excavating with my X-acto blade. As I uncovered the bone, I realized it was not a tooth. I started noticing these very fine crescent shaped objects (which I unfortunately did not photograph). So I decided to give the poo a little vinegar bath overnight. As I lightly removed an unremarkable bit of fossilized fecal mass this morning, it split a

What was for supper? Did they love meeces to pieces in the Oligocene?
GeschWhat posted a topic in Fossil ID
Since I couldn't go out to dig for fossils, I decided to go on a micro dig. Today's dig was in a coprolite fragment from the Oligocene. Prior to excavation, the broken face of the coprolite looked like this. You can see a little bit of bone peeking through. After about an hour of excavation under 40X magnification, I uncovered what I think is a rodent tooth and possibly a toe bone and claw??? What do you think? Does anyone out there know their Rupelian rodents? Grinding Surface of the tooth: Side view showing roots: Small toe bon- 14 replies

Hi all, trying to get some id help with some teeth from the Brule Formation, Nebraska. Most i think are oreodont, mesohippus and similar. Unfortunately dentition is not my forte, so any assistance would be appreciated. Tried to take photos from three different angles to help. Set 1, 2-specimens Set 2, 3-specimens (lower 2 mesohippus maybe) Set 3, 2-specimens Set 4, 1-specimen Set 5, 1-specimen (mesohippus maybe?) Thanks for everyone's help again. MUCH appreciated, Paul

Hello fossil friends, Picked this beauty up recently, but I was told no more than "Oredont from Wyoming". From this, I deduce Merycoidodon culbertsoni, from the Brule Formation. Is this correct? All responses are appreciated Thank you!
