3 years, 1 month ago3 years, 1 month agoGreetings @jon-thele ! From your uploaded specimens, I’d have to say the geochronology of the specimens you’ve found are broadly Tertiary and from the either the Belgrade or River Bend Formations. They are located just inland from Onslow Beach and likely washed out of the estuaries and came in with the tide onto the beach.
