I’d like to see the Pliocene fossils from California that people have I’ll start off with some fossils I collected from the Purisima formation at Capitola Beach A vertebra with a shell on the back A heavily eroded whale vertebra with some associated (rib?) bones Some cool clam shells Edited to add: Here’s a clam shell I dug up from the Pinole Tuff formation when I was 7. It was the first fossil I ever found

Purisima Formation (3-7 Ma), Santa Cruz, CA: One piece doesn’t match the rest
Slow_BS posted a topic in Fossil ID
Hi there, I have a collection of Santa Cruz, CA shell hash, from the Purisima Formation. It’s pretty much all non-mineralized mollusks, I think. I received a new piece that seems to be from the same formation (it was a gift from the heir of the original collector who lived in Monterey - the other side of the bay from the formation). The fossiliferous pieces inside this one have a totally different structure - much more of a radial/flakey look. I circled it in red in the first picture, and it’s the only rock in pics 3-6. I’d love to here if anyone has any thoughts on whether the new piece is Purisima, and what the white portions may have been. Thanks for reading!

I'm working at the University of California at Berkeley and we decided to field trip it to the Museum of Paleontology in the Life Sciences building. I haven't posted in nearly a decade but saw this and had to. Bobby!

Found on the beach in Capitola, CA. The tooth is wave-worn and fractured lengthwise. Pinniped of some sort seems most likely, although I haven't seen this fingerprint-like pattern of dark blotches and lines on the enamel surface of other fossil pinniped teeth from this locality. It's unclear if is simply mineral staining, or might be a diagnostic aid to identification. Boesse may have seen this before. Length is 43mm x 16mm across the break.

I found these items years ago in Capitola, CA, where the Purisima Formation is exposed in seaside cliffs. They were found in the gravel 'float' at the base of a cliff. Both objects measure approximately 20x15x7mm, and are nearly identical in form. The concave side retains traces of the sediment typical of the Purisima at that location, and the convex side shows rounded ridges approximately perpendicular to the object's major axis. They have a somewhat similar color and density to bone fragments also found that location. It may take someone who has experience with the Purisima, or a trip to UCMP and/or SCMNH to get these objects identified, but I'm hopeful that someone here can shed some light on what they are.

Here are a few different pieces I picked up near Santa Cruz, hoping to learn a bit more from everyone here and get some help with ID's. My guess was a smaller marine mammal, maybe a pinniped rib?

Hello Fossil Forum! I live in Northern California, and have been learning about the geology and fossils of our area so I am very excited to have found this forum. From what I have found so far, I believe the fossils I have been collecting are from the Purisima formation based on the location and appearance. These were collected near Santa Cruz, so hoping to get some more info and possible identification.

Possible Fossil Bird Claw? Purisima Fm, Miocene, Capitola, Ca
kimberlight posted a topic in Fossil ID
Hi, My 12-year old son and I were fossil hunting in the Purisima Fm (Upper Miocene; 3- 5 MY) at Capitola, CA for his birthday (today). We spotted what appears to be a claw?? It may have come from a Pliocene/Pleistocene sandstone from above the Purisima, as the boulder was not in place. The "claw" is curved and has a hole in the tip. At the base, there is a ball-shaped structure. Can anyone confirm if we are right, and if so, identify it. If we are WRONG (wouldn't be the first time), please give us the correct answer. Regardless, this was a fabulous B-day present for this paleontologist wanna-be. Thanks, Kimberlite
