Hi all, I have this slab that is composed of a mix of sandstone and clay matrix. One side is more heavily composed of sandstone while the other half is more clay. In the sandstone side is a well preserved mandible from Aepycamelus sp. seen from the lateral aspect. It was crushed along the sagittal plane allowing us to see the medial, lingual aspect of the other side of the mandible from behind. Because the mandible is crushed, I feel this piece would be best suited at a slab specimen, if you guys have any opinion please share. Now, the clay rich side appears to not have preserved as well but t

Hi all, I have some interesting bones that I found today. The one appears to be a phalanx but it doesn’t appear like any of the horse or camel material I’ve been able to find online. I also believe that the tooth fragment belongs to order Carnivora, although I’m not sure what. The researchers found a maxilla to Osteoborus diabloensis at this site but again, I have no clue in the matter. Also note, the phalanx has a lichen growing on it, which tells to the degree of time it’s been resting on the hard desert surface. Thank you to anyone that can provide any ideas/resources/IDs.

Sponge fossil from the late Paleozoic of southern Nevada?

Wanted to share this hoof I found yesterday. Not entirely sure which exact species this is but is likely neohipparion based upon the literature.

Hi all, I found these interesting fragments of tooth enamel by themselves and they both appear to have a cusp like shape and the one has a rounded top that didn’t fully break off. The larger piece has some very pronounced horizontal striations, Im not sure if that’s helpful it not. Could these be pieces of mastodon tooth? I know several Pacific Mastodons were found in this area.

Hi all, I was hoping to get an ID on these two bones I found today. They both have a stylus and at least 2 facets for articulation. I’m guessing maybe some foot bones? -also I’ve been gluing this long bone together with some paraloid B-72. I have both distal and proximal heads, but without knowing the type of bone, you can imagine it’s difficult to piece together. I just have finished all but those two aspects, I have roughly about 5” of bone left and I’m currently at about 17” in total length. Could it be to a camel? What bone may this be? thanks in advance!

I ordered this plate of trilobites a while back and just recently noticed something peculiar on the side of the rock, i’m pretty sure this is not a trilobite but it still looks somewhat organic, but i’ve got nothing. Any ideas!

Hi all, I found these teeth at the same locality as my last two posts. I have more images to follow of some complete phalanges I have found but for now I’d like some help with these teeth. One I think may belong to a camel as both Paracamelus and Camelops were found in this locality and the other I am unsure of. The possible camel tooth isn’t far below the bone line so maybe it was unerupted? Any ideas would be great.

I found a number of fossilized bone fragments on the surface in an area of North Western Nevada which the geological map lists as "basalt flows- Pliocene- Holocene. " Any help on identifying what they might be from would be appreciated. I did try the burn test and I could not get it to smoke or have any smell that would indicate that it is not mineralized.

Hi all, I recently found this tooth in a formation dated to the middle Pliocene in Nevada. I believe it belongs to Antilocapridae, possibly a pronghorn. I’m looking to see if any one on here is familiar with western fauna of this period and could give me some more insight. thanks in advance!

A Worldwide Bibliography of the Grand Canyon and Lower Colorado River Regions (open access PDFs)

I found this small fossil recently. The surface geology was young volcanic- andesite and basal flows pretty much exclusively. This fossil seems to be from a previous geology that has worked its way to the surface. Any help on id would be appreciated. Small fossilized bone fragments were also found in the general area but I'm thinking this is from an invertebrate but I really don't know. It's about 5mm x 5 mm in size.

Hi all, I found this washed out of a sandstone wall at a formation dated to the middle Pliocene in Nevada. Someone suggested I post it here but their hunch was that this is a metapodial to some carnivore. The diameter is 1.7 cm, length is 9.6 cm. Thanks in advance for any ideas!

I’ve recently bought these trilobites from the Chisholm shale in Nevada, and I was looking for an ID on the two of them. They are Cambrian in age, and more specifically from Lincoln County.

I found this in the Nevada desert a couple of months ago, I think that its petified wood but I would like a second opinion

Trying to find out what this is. Found in the Northern Nevada desert. It looks like a round tree trunk 10 inches across. Half of the outer surface is somewhat smooth and the other half has a stepped pattern that reminds me of how some plants grow stems upwards. The pic that shows this section maybe upside down. The photographer and I aren't sure whats up or down. The texture is like glass, we think its opalized? Very sharp edges and smooth. It's brittle. The color is brown on outside with white calcium patches. Inner area is a solid carmel color with tint of green, there are no flashes of rain

Hey everyone, I’ve been meaning to get this post up for a few days but I’ve been dealing with my poor cat inky (Sweetheart of a cat) who is on her final day of life today. I will have to put her down November 1st. Very sad time as she’s been my companion the last 13 years. I’m sure many can relate. I’ll try to keep the chatter short and just get up as many photos I can for you kind people on the forum to enjoy. I just got back recently from an amazing trip to Utah and Nevada (Oct/11/2020-Oct/18/2020) Where I was camping in the field and trilobite collecting for 6 days s

Any help identifying what this might be would be appreciated. Found in western Nevada near the Reno area. All of the geology around it is relatively young volcanic rocks, mostly rhyolite. But there is about a 6 acre area that appears to be an inlier formation of an older geology. I found this about 6 inches under ground while looking for some other rocks that were interesting. It looks similar in color and shape to some dinosaur teeth I have seen. The swirled nature of the material is unique to anything I have found online. I will post more pics in the comments.

Ammonites, Trilobites, Fossil Fish: Another Western Adventure
Jeffrey P posted a topic in Fossil Hunting Trips
Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:- 67 replies

Hello TFF! I found these two pieces in Nevada while looking for some Carboniferous shark teeth and hope I found one. They were located in the Bird Spring Formation north of Vegas which is Pennsylvanian in age. #1 and #2 which could just as well be a brachiopod... Thanks for looking!
