Hi, @James-baxter2 – did you mean to post the same fossil twice? I can delete one of them if you want. If you were looking for identification help, the What is it? Group is more valuable and I can tag in some shark experts. Thanks, Jen

I used to live in Scott’s valley! Fantastic find!

i deleted the double. i meant to post a smaller one i found the same day. any help identifying would be appreciated. i cant wait to go again! its incredible finding something no one has ever seen that millions of years old. that shark had no idea he would make someone happy and excited millions of years later

@jeanette-pirlo, do you have any idea what kind of shark this may be? I imagine @bill-heim will have some insight. We have a group called ‘shocking shark teeth’ that may be most suited for any future posts on sharks!

I’m not sure. When I lived out in SC/SV I didn’t really pay attention to the fossil record, I was focused on modern marine bio. Perhaps victor might know

should i repost it to shocking shark teeth or can i change the group

Santa Cruz Sandhills Geology

The Santa Cruz Sandhills occur on Miocene marine sediments and sandstones of the Santa Margarita formation (right)–a highly weathered arkosic (high feldspar content) sandstone. 

As evidence of their marine origins, the Sandhills feature many fossils of sand dollars (upper left), bivalves (lower left), and gastropods, as well as sharks teeth. Thick beds of fossil sand dollars (right) are found underneath the soil surface in Sandhills habitat between Ben Lomond and Scotts Valley. The presence of this layer is correlated with the occurrence of ridges which support sand parkland–a rare community within the Sandhills.

Hi @james-baxter – you cannot change the group, as of right now. I’ll tag in @vperez as well to help with the identification.

Hi @james-baxter , your tooth is from the extinct hook-tooth mako, Isurus planus.
