Hi everyone, I was just browsing @PrehistoricFlorida's website and my eye was caught by what was labelled as a pocket gopher femur (trust me there were many more impressive fossils that caught my eye as well). Reason being, I found a very similar bone on a hunt in South Dakota's Hell Creek formation back in 2019. I kept it, hoping in my heart of hearts that it was fossilized, but keeping my expectations low. The rusty staining on the bone made me think there was a chance it was just a beautifully preserved Cretaceous limb bone, but I knew it was most likely recent. It's about 2.5 cm long and .

I've been in the lab this fall/winter but preparation has taken a back seat to the plastics/replicas operations. As things start to wind down with plastics around this time of year, I'm embarking on my next prep project. This specimen is from the same Wyoming locality as the Herpetotherium I posted about recently but was found many years ago(~15?). It appears to just be an upper skull of a small rodent but there is some hope for lowers. I pulled this piece out of its field packaging in April but just now starting preparation in earnest. So far, all I've done is rough prep around the bound

From the album: Brazos River Finds--August 2021
-
So I picked up a small piece in the sandy Brazos River bed the other day because it looked like there might have been some tooth enamel, but it was so covered in a sandstone matrix that I wasn't sure what it might be. The sandstone wouldn't come off with water, but when I dipped it in vinegar last night, it started to melt away. I pulled it out quickly and rinsed it with water and realized it looks like a set of top and bottom front teeth. Maybe rat? My problem is this: the matrix is hiding a lot of detail here, and I'd ideally like to clean it off completely. But it

I found this mandible (I think) near Bloomington, Indiana over the weekend and was wondering if anyone could give me an ID on it. I believe it's the mandible of a rodent, but that's about as far as I get. Seems to large for a mouse or rat, but maybe a muskrat, shrew (if those are bigger?), or squirrel? And I'm guessing it's more recent rather than fossil?

Good morning! Found this little interesting tooth in my Post Oak Creek matrix. Did a bit of online research and have concluded (tentatively) that it is a vole molar, possibly Pleistocene? I don't think it's modern because of the coloration. I have seen that fossil rodent teeth have been found in POC matrix. What do y'all think? Size 4mm

With my last project wrapping up, this small skull was sitting on my desk and needs to get done. Way too much of my collection is in a half done state. Eumys is a cricetid, which includes modern voles, hamsters, mice and rats. When identifying one, the primary character I use is the shape of M1 and the fact it has no premolars. It's the only White River rodent I'm aware of with 3 teeth in the maxilla, most have 4 or 5 (I am prepared to be contradicted ) . M1 is very distinctive in that it has 5 cones. My plan is to remove the matrix from the side of t

Found this on my 2018 trip to Florida, I believe it is a rodent incisor and I would like to confirm that. And if it is, does anyone have any indication as to what variety it belongs to? It's about 2 cm long.

Small, Medium, and Large...Rodent Teeth? Post Oak Creek, TX
UncoilingGLaDOS posted a topic in Fossil ID
Found these little fragments when looking around in Post Oak Creek near Sherman, Texas. To me they resemble rodent teeth, and I've certainly found non-fossilized ones out there, but these are definitely fossilized. Any idea what they could be? Largest fragment is 16mm long and 4mm wide. Close up shot is the wider end of the fragment, which shows a really cool cross section of the piece.- 14 replies

I found this in a large shelter outside of Austin, Texas. The cave was scattered with Flint and various animal bones.

Cheek tooth from the theridomyid rodent Isoptychus sp. Collected through screen washing of matrix from the 'White Band' a shallow freshwater lacustrine horizon.

Lower incisor from the theridmoyid rodent Isoptychus. Collected from a thin lacustrine horizon in the Lower Hamstead Member of the Bouldnor Fm. at Bouldnor Cliff, an early Oligocene locality on the northwest coast of the Isle Of Wight, UK. Identified by mammal specialist Jerry hooker from the Natural History Museum.

I am interested in a specific ID of this piece of rodent mandible. When I found it I immediately assumed it was mouse but then I decided maybe it is a bit too big for a mouse so I started studying small rodent dentition charts and was amazed at all the variations in the molars. Another hour in the internet rabbit hole (no pun intended). 7/8" in length (22mm), found in Florida's Peace River in a mix of Miocene and Pleistocene material.

Found this in a creek off the Rappahannock River mixed in with Found this in a creek off the Rappahannock River, Virginia mixed in with shark teeth. Curved (semi-circular), chisel on one end (two tone color), hollow on other end. No idea what the stuff stuck to it is.

I found this in a creek leading to Grove Lake in Antelope county NE (near Ashfall fossil beds) I've found a lot of bone fragments and teeth there before, but this find was particularly interesting. Anyone know what type of rodent it is from and if it is from the same time period as the many mammal fossils at ashfalls?

Here's another jaw I found on the Brazos River. Hope someone can help me id it. The total piece is 4 inches long and the length of the longest tooth is 3/8inch across the top of the crown.

Found this little mandible today. Galveston Bay dredge spoils late Pleistocene. Unfortunately no teeth but does this look like Leporidae? If so rabbit or hare? Darrow
