So, Bob... Are those teeth from the Scientists cliffs? we used to go down there (from Jersey) all the time for sharks teeth and such when I was in high school and college... 1967 to about 1975.
One time, we found a Porpoise skull in the cliff and as we had our picks and brushes with us, we took a few hours to get it free. On top of finding alot of shark teeth, I also found a whale ear bone and 2 porpoise ear bones as well as a porpoise tooth... and alot of shark vertebrae. My largest shark tooth was about 3" on the edge.
Mid way thru our times down there is when they built that nuclear plant and fenced off all of the materials piled up so we "couldn't hurt ourselves" and then sue the power company.
I do miss walking along the cliff edge looking for fossils. Thanks for taking me back.
