Can someone please help identify if this is a fossil and what it is?
J Dub posted a topic in Fossil ID
Hello to all. I would appreciate some help identifying if this is a fossil and what it may be. I found it in a canyon in San Diego and plan on taking it to our local natural history museum if it turns out that is something worth taking. Thank you in advance for your help.- 6 replies

Hi all, Came across this along the beach in La Jolla Farms in what appears to be sandstone or siltstone that fell out of the cliffs, initial guess it's Delmar Formation or Torrey Sandstone. Initially thought it's dendrite but getting a gut feeling that it might be a plant fossil. Any opinions? Thanks!

Hi all. Dropping some photos here. Believe one of the bones could be a carpal of a baleen whale? Not exactly great with anatomy. Would type more at length, but recently broke MY fifth metacarpal playing with my daughter and typing is not so fluid. The finds are from the San Diego formation. Pliocene era - very rich. Will post some other finds of manatee bone and great white teeth later when I can dig out. Also have some Eocene mollusk finds. I grew up mineral and fossil hunting as a youth with my parents and family friends. I revived the interest over the past 8 years and recently moved back to SD from Oregon where I really had no time to hunt. My academic background is in biology (B.S) and pharmacology - where I recently earned my PhD in toxicology/cancer research. I have plumbed the San Diego formation for years on and off, but I am now trying to look out new spots in the area - particularly for Eocene era fossils from the Mission Valley/Stadium formation. My sense is that these are much, much less rich and exposed - but I want to keep snooping. These Eocene formations represented a time when SD was a floodplain, fed by the massive Ballena river that deposited a huge alluvial fan across the county (as I understand). Anyhow, just rambling and introducing myself. Actually, I had an account here in 2016, but since have lost access to it because of lost password and cant access old email. Old username was 'Cetacean'. Will post more stuff soon if folks want to look.

Advice for Obtaining Fossil Hunting Permission
Thecosmilia Trichitoma posted a topic in Questions & Answers
I have recently been researching several local road cuts that expose fossils, and am interested in obtaining written permission/ a permit from Caltrans to surface collect there. I would like to know if this is possible for an amateur collector, and if anyone has personal experience obtaining collecting permission from government agencies. I would also appreciate any recommendations for obtaining this permission/ information to give when applying. Thank you!- 5 replies

I have been looking into a new fossil site exposing the Bay Point Formation in San Diego, CA. I want to see if it would be legal for me to go collecting there, as it looks like it could be a good exposure. The signs around it say that it is a "Natural Park commissioned by the City of San Diego." I couldn't find anything on Natural Park fossil laws when I looked them up. Does anyone know of the regulations of them?

Took this photo of an unnamed eschrichtiid from the Pliocene San Diego Formation of San Diego County in March 2019. Until the 2000s, the fossil record of gray whales was confined to the Pleistocene, but thanks to the work of Michelangelo Bisconti, it is apparent that gray whales emerged about the same time as the oldest rorquals (Eschrichtioides was long considered a balaenopterid, but eventually recognized as a gray whale relative).

Balaenid from San Diego Formation of San Diego County, California
DD1991 posted a topic in General Fossil Discussion
The balaenid specimen SDNHM 43880 I photographed at the San Diego Natural History Museum in December 2017 was once referred to Balaenula, but Churchill et al. (2012) recovered it as sister to the bowhead whale rather the right whales and Balaenula, and recent erection of Archaeobalaena dosanko for the one balaenid specimen from Japan previously referred to Balaenula makes clear that the previous referral of SDNHM 43880 was untenable. However, it is unclear whether SDNHM 43880 is a new genus and species or alternatively a new Balaena species due to the cladistic position of SDNHM 43880 obtained by Churchill et al. (2012).

Hey everyone pretty new here. My wife and I were at the beach collecting shells and I noticed some erosion on the cliffs and found these in the ruble. I think these are fossil plants. Looks to me like a leaf and fern? I’d love some help putting a name to these if possible. USA, California, San Diego, Sunset Cliffs on the beach

Found this artifact in Black's Beach, San Diego. Looks like a 6-ft scorpion. A Eurypterid maybe? I video and 3D scanned the find and sent it to The Nat and ROM (Toronto). Waiting for a response. Here are a few pictures. This ditch is likely to have been dug by the recent rains. Compare the size to my wrist watch: Closer look: Wavefront .obj file: Hit me up for high-res images, obj file, video, etc. Thanks!

Why do southern californians go to Diamond Valley for fossil hunting.
whovin posted a topic in Questions & Answers
People have told me to go to Diamond Valley, They said there are lots of fossils there. The lake is man made though. Paleontologist already dug out the fossils. So what is so good about it.- 6 replies

Walking my dogs in the canyon today behind my house and found this. It was on a dried up river bed next to an incline where the recent rains knocked a lot of stuff down. I’m located in in San Diego and found this is the mission valley area. Looking foward to learning a lot from this forum. I’m 23 and very new to fossil hunting but have gotten lucky a few times camping.

Here is a nice little gastropod cluster on the matrix that was rescued from a construction site along Reynard Way in San Diego. I think they are in the family Naticidae and are possibly Polinices galianor. Anyone have any thoughts? I'd love to nail it down more specifically if possible. Naticidae "Reynard Way" ~3-1.5Mya Pliocene to Early Pleistocene San Diego Formation San Diego County, CA Kingdom: Animalia Phylum: Mollusca Class: Gastropoda -- Subclass: Caenogastropoda Order: Littorinimorpha Family: Naticidae Genus: Favor Polinices?

I headed up to Lawrence Canyon last week and this is what I found. Looks like the area is finally being developed. Say bye bye to another interesting and productive San Diego site. In honor of the site, here are a few of my favorite finds from Lawrence Canyon. I'd encourage everyone to post their favorites too.

I have not run across many San Diego based fossil collectors who go out regularly. I am out 2-3 times a week and am always exploring new "legal" areas to potentially collect from. Besides the occasional trips to the desert, anyone know of San Diego based fossil organizations or people who are active field collectors?
