Macrophyseter Posted September 5, 2017 Share Posted September 5, 2017 Looks like a turtle shell to me. But please state where exactly you found this so we can find out easier. If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...

Darko Posted September 5, 2017 Share Posted September 5, 2017 1 minute ago, ynot said: Area is too old for a turtle. Then maybe it's some kind of seashell part.Idk, maybe i'm wrong this time. Link to comment Share on other sites More sharing options...
abyssunder Posted September 5, 2017 Share Posted September 5, 2017 It looks like an oyster valve with predation marks on the inner surface of the shell. 3 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

sTamprockcoin Posted September 5, 2017 Share Posted September 5, 2017 Based on the Poster's location (lacking a more detailed collecting site location) and some of the structure in the "matrix" , I'd suspect that its a metamorphic - shistose- formation, perhaps from a transitional area between sedimentary/metamorphic. According to the PA geologic Survey maps and my own collecting in the area this is a tightly folded area so a fraction of mile can make a big difference in basic rock type. Perhaps exposing the underside (by breaking off a piece) of the "coating/fossil" might reveal structures to clarify mineral or biologic origin. 4 “Beautiful is what we see.
