I picked this up from a dried up river bed about 16 years ago.

 

Santa Barbara, 154, Cold Spring Tavern area, approx. ele. 1800'

They look like oysters to me.  Such fossils are common in Miocene and maybe other formations in the coastal mountains in southern California.

I agree. They look oyster shells embedded in the matrix, considering their shape and multi-layered structure.
