@bill-heim The specimen number is my own naming scheme for specimens in my personal collection. I have the coordinates from a GPS app from my smartphone, I just didn’t include it since the website is visible to the public and @kevin-kelly is doing a survey of the sharks at that locality with the LA County Natural History Museum. This will be…[Read more]

Hi there, @kevin-kelly, wonderful find! @vperez or @bill-heim might be able to help you with the identification!

Hi, @Kevin-Kelly! Are you planning on going back through these and IDing them yourself first?

Hi, @Kevin-Kelly, could you post photos from the other side?

Hi, @Kevin-Kelly, can you upload photos from other angles?

Hi, @Kevin-Kelly! You’re right, this is a brachiopod. Sorry, I was completely wrong.

Hi, @Kevin-Kelly, @Bill-Heim should be able to help with ID!

Hi @Kevin-Kelly, I think this is a sea urchin spine.

Hi, @Kevin-Kelly. I see that this tooth is pretty destroyed. At the very least, we can identify it as a shark tooth, so the taxonomy should be Kingdom -> Animalia, Phylum -> Chordata, Class -> Chondrichthyes

Hi, @Kevin-Kelly. The info and photos here look good to me, but I’ll tag in @Bill-Heim to check the ID.

Hi, @Kevin-Kelly! I think the Pico formation is Pliocene in age. I will tag in @Bill-Heim for ID confirmation.

Hi, @Kevin-Kelly! This looks good to me, but I am not an expert in sharks. I will tag in @Bill-Heim for ID confirmation.

Hi, @Kevin-Kelly! This looks good to me, but I am not an expert in sharks. I will tag in @Bill-Heim for ID confirmation.

Hi, @Kevin-Kelly. I think this is also an oyster.

Hi, @Kevin-Kelly! I suspect this is a crab claw but photos from other sides and angles would be useful.

Hi, @Kevin-Kelly, I’m thinking this is part of an Oyster (genus Ostrea).

Hi, @Kevin-Kelly! Could you post more photos of this specimen from other sides + angles?

Hi, @Kevin-Kelly! I’m thinking this is half of a bivalve. It’s pretty poorly preserved though, I’m not sure we could ID it past that.

Hi @Kevin-Kelly, would you be willing to change the genus name?

Hi @Kevin-Kelly, I think the best thing to do here is to change the taxonomy to reflect Physogaleus sp.
