CaraMarie Posted July 18, 2021 Share Posted July 18, 2021 (edited) I found this about 8 years ago in a dried up creek bed behind my house in the hills of Hayward, California in the San Francisco bay area, USA. We dug it out of some dry but soft sediment and I assumed I found a fungus/mushroom of some sort but now Im not so sure. I am a hobby collector and love it no matter what it is but I would love to have an actual identification. Thanks!

Al Dente Posted July 18, 2021 Share Posted July 18, 2021 It’s coral. Maybe someone familiar with the fossils in the area can narrow it down more. 3 Link to comment Share on other sites More sharing options...
CaraMarie Posted July 18, 2021 Author Share Posted July 18, 2021 That is exactly what I was thinking. As I learned more about fossils I started to doubt my first impression of it. Link to comment Share on other sites More sharing options...

DPS Ammonite Posted July 19, 2021 Share Posted July 19, 2021 There are reported corals from the Oakland Hills and marine rocks of Cretaceous to maybe the Miocene. If you PM me the locality, I will try to see what likely rock units via a geological map that the fossil came from. Contact my friend Andrew Alden who has a great website on the Oakland and surround areas geology. He tried to find corals in one of his posts. https://oaklandgeology.com 1 My goal is to leave no stone or fossil unturned.

DPS Ammonite Posted July 19, 2021 Share Posted July 19, 2021 Andrew said contact the UCMP. He thought that the rocks were Cretaceous or Pleistocene with nothing in between. I think that Cretaceous is a good bet. @HansTheLoser 1 My goal is to leave no stone or fossil unturned.

abyssunder Posted July 19, 2021 Share Posted July 19, 2021 If we exclude corallites, I can see why do you think it's a mushroom. Nice specimen!

HansTheLoser Posted July 25, 2021 Share Posted July 25, 2021 Thanks for attracting me to this post. It is too young for Cretaceous and I think shallow marine Cretaceous is rare in California. I rather guess Neogene. Link to comment Share on other sites More sharing options...
