Found this on a cove near Palos Verdes CA wondering is it a fossil shell or something modern, looks something like a murex, but maybe a whelk ???

So I’ve just come back from the Barack and clean up what I found (removed all sand and gunk) and I had come across some shells, unusual crystals (probably quartz) and a fossil leaf and stem imprint (for size the red shell is around the size of the average hand) If anyone has any info on any of these would be a big help

What is the age of the oldest known non-permineralized shell?
Eye in the Sky posted a topic in Questions & Answers
Recently, a group of paleontologists were having a discussion regarding fossil shells after a woman produced one for identification. Discussion turned to the difference between a shell and a fossil shell (that being a shell which has permineralized). There was debate as to whether or not there are any shells that are older than any fossil shells in the general paleo record. One of the paleontologists knows a shell expert and she reported back that the oldest known shell is approximately 18,000 years old and that all shells older than that have permineralized. However, some found this difficult to believe, as shell material, being mostly calcium carbonate, should be able to survive for very long periods in non-acidic deposition environments. Can anyone confirm this? Thanks! -

This is a very rare find at this site. Although two members of the genus have been reported along the C and D Canal, this is the only one I've found at Reedy Point in 17 years of collecting there! PLEASE NOTE: It is possible that this was carried there during frequent human activity - perhaps in a tire tread from a vehicle that came from another site along the canal. This specimen has a 4mm pearl bud near the hinge on the interior side of the valve. Because there are more than one species of Pteria at the canal and this shell is heavily worn, I am refraining from narrowing it down to a species. Of the two reported, only one really resembles it. P. petrosa (Conrad) has strong, concentric growth rings, but no costae. P. laripes (Morton) has strong costae and fine growth lines, so is probably a match.

Fossilized shell from Tampa Bay Florida 23-34 million years old
Gregcohen posted a topic in Fossil ID
Can anyone identify this 1ish inch shell that is agatized that dates back 23-24 million years ago found in Tampa Bay Florida? Does anyone know a paper that references these? I use muriatic acid to clean limestone chunks of agatized coral stick. Many times I come across other items like this. Corals and shells. Just trying to get a better idea of some of the items I found. This was left for me by mother nature on a storm Christmas eve 2020.- 11 replies

Hi all, I recently obtained several lovely ammonites from the late Triassic (Carnian) Xiaowa Formation of Guanling, Guizhou Province However, I lack the expertise to identify them and I was hoping you could help I suspect A is a Trachyceras multituberculatum as this ammonite type is abundant there, and that species is also the most common ammonite there I can't tell what B and C are. I am not even sure if C is a different species from A. From my research, the following species are also present there: Trachyceras cf. aon Paratrachyceras cf. hofmanni Paratrachyceras douvillei Hauerites cf. himalayanus Protrachyceras sp. Arctosirenites canadensis Arctosirenites columbianus What do you think?

So, while looking for shale that may have plant imprints (nadda ) or conodonts (also nadda ) and finding absolutely nothing splitting open countless layers (I wanted to make the shale layers in Kansas City look uniform so I've separated all of them for future fossil hunters ) I came upon this single fossil. To me it reminds me of modern-day smooth shelled limpets. This black shale layer was between winterset limestone and Sniabar limestone layers in Kansas City (from R. Gentile). It is about 3/8" long by 2/8" wide and a little over 1/8" thick-two different "lightings". Thoughts, as usual, much appreciated! Bone

found in a hill area of central MS in a field, sorry I can not remember county or city... when searching with MS Gem & Mineral club, we are talking about about 5 hours from coast area. I do know it is an oyster but was wondering if anyone had any idea the possible time frame of age.

Hello. We did some exploring yesterday and found our way to the St Johns River in Deland. I love shells and picked a nice heavy fossil up that was lying near the water in the sand. Picture is attached. I think it is a Spiny Jewel Box without its spines but it is at least 2.5" and I can not find any documentation that said they were that big. Can anyone tell me if it might be something else? Thank you.
