Hi all, I’m sure this is an obvious one for some of you experts out there, I just haven’t come across a tooth like this one yet. There is still a bit of matrix on the chewing surface but it’s mostly prepped. I know many of you are out East so I don’t expect a species, but it’d be nice to at least find out the genus or kind of animal so I can research from there. thank you all as always!

Hi, I have this mystery piece of what appears to be anomalocarid appendage of sorts. The problem is I did not receive any information with it and it came out of an old collection from Maine, Usa. I'm not to sure what else it could be from the appearance but I am also very uncertain of the exact species. The piece of a very laminated sparkly shale If I had to guess it could've came from either Burgess Shale, Utah, or Nevada but I not sure what locality it could be from so if anyone if familiar with these shales and can tell from the preservation it would be a huge help, thank you and looking forward to seeing peoples opinions, and if anyone can recommend an expert to show that would also help.

first of its kind in NA? I don’t want to disclose much about the location found for now except that it was at a high elevation. It was a very “just by chance” way to find it after I got lost. I was not looking for fossils nor am I a fossil collecter. Have not showed photos to any expert.

Fossil Record of Fish Morphology altered by Single Pattern Formation Gene
Biotalker posted a topic in General Fossil Discussion
Here is a fine way to spend 16 minutes. A wonderful (even if simplified) story of a gene at the top of the hierarchy of limb formation in tetrapods, and the identification of a mutation in the gene that causes a dramatic change in fish's morphology. It is remarkable that the mutation doesn't affect the protein sequence but the switch that turns it on or off in different tissues of the developing animal. Why would this be of particular interest to you? Because shown herein is the remarkable correlation with the fossil record of this small fish. So grab some popcorn, or better yet a beer or glass of wine and enjoy yet another page of how scientific research illuminates.- 1 reply

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 there is an intact scapula that was already cracked badly and after jacketing and transport, the pieces shifted a bit. How best should I address this? I was thinking using paranoid B-72 but was hoping if any of the masters here have any insight or advice.

From the album: Trilobites
Due for a revision! -
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.

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.

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!

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!

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 rainbow colors or clear crystals. There are no other patterns, dots, striations, or wood like grain. It was found among volcanic and igneous rock field. Searched for more similar but none found on surface.
