Allin69 Posted November 27, 2018 Share Posted November 27, 2018 Found In scotia, ca. How do you determine how old? And what's a good solvent to loosen up sand stone Link to comment Share on other sites More sharing options...

ynot Posted November 27, 2018 Share Posted November 27, 2018 Looks like a mudstone with bio eroded holes. Not sure if any solvents will have an effect on it.. Darwin said: " Man sprang from monkeys."

Tidgy's Dad Posted November 27, 2018 Share Posted November 27, 2018 Not a turtle plastron, i'm afraid. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Innocentx Posted November 27, 2018 Share Posted November 27, 2018 The shape may have been suggestive of turtle. I have a similar septarian nodule with same shape and lines that almost looks like turtle, but scutes(plates) are in wrong positions. Welcome to the Forum, @Allin69 !!

abyssunder Posted November 27, 2018 Share Posted November 27, 2018 It might be a septarian nodule.

goatinformationist Posted November 28, 2018 Share Posted November 28, 2018 Horribly worn Brooksella? Link to comment Share on other sites More sharing options...
ynot Posted November 28, 2018 Share Posted November 28, 2018 This piece is a typical mudstone that is common all along the california coast. Not sure of the formation, maybe monterey(?). Most likely miocene or more recent. It is not a septarian or a brooksella. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
