ID request round items on rock

Recommended Posts

dsludden

Good morning, this item is cross posted on Facebook. This cool rock was found in the surf at Onslow Beach in Jacksonville NC. There are Gastropods, unidentified shell and mystery circles/ovals by the hundreds if not thousands. My question is what are these little round areas? The rock is shown wet in order to bring out the features listed. Size 1.5” x 1”.  The rock is smooth to touch despite seeing texture in photo.  Thank you in advance!

Maybe some form of mineral stained oolitic limestone.

You have a sea snail fossil on the first photo. Looks like a turritella and sea snail on the second photo.

Those are ooids of oolitic limestone. :)

I agree with the others.
