Pectin Fossil ?

I would agree.

Take a closer look, that is actually a shell in the rock.

I agree. Section of scallop shell fossil.

That scallop shell fossil is beautiful. Thanks for the input. I think you may have nailed it!

Just don't read past the first couple forums! You might get to the Fossil and Rock/Gem forums. We wouldn't want you to have to read to much.

I was going to say "Bigfoot", but it's a proven fact he only has 5 toes.

They nailed it! It is a fossil in a rock for sure, probably the pecten species.

I tried looking up the age...it went from 70 million to 0.0 million...meaning?

 

[Charlie P. (NY)]

The creature has been on earth and available for fossilization for the last 70 million years.

Some of the Pacific Coastal fossilized pectens are a mere 2,000,000 years old. Young compared to most others.

IMO - dont hit me -
marks look modern
the grooves do match the the stones patina
fresh marks
prop marks?
manmade scuffs
