jpc Posted September 7, 2017 Share Posted September 7, 2017 The ship ballast is a great theory. Much better than it being a native MA fossil. It also happens to look a lot like UK preservation of ammonites. The other option is a glacial rock churned southwrd during the Pleistocene. Both are just hypotheses, but I like the ballast idea better, mainly because of the European preservation. If anyone can show us preservation like this from north (even well north) of Beverly, that would be OK, too. Would they have been using some sort of heavy machinery (in post- colonial days) to load ballast rocks? If so, little guys might be in among bigger rocks, or this popped off off a bigger rock. Coll fossil. Esp for Mass, my home state. Link to comment Share on other sites More sharing options...
Plax Posted September 7, 2017 Share Posted September 7, 2017 if this is an ammonite then I agree with your possible source. Link to comment Share on other sites More sharing options...
JohnBrewer Posted September 7, 2017 Share Posted September 7, 2017 I'm not convinced it's an ammonite. John Map of UK fossil sites Link to comment Share on other sites More sharing options...

abyssunder Posted September 12, 2017 Share Posted September 12, 2017 It's an worn ammonite imprint in rock, like the central region of the one below. comparative picture from here " 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.

Why did I forget that word when I posted that? If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!
