Here's the cliffs; in this picture above, the ancient seabed is the dark stuff at the base of the cliff.
Here's a better shot of the fossilized layer.
Even closer view, you can see all the shells and such.
This was all we (and by "we", I mean "my brother, who actually knew what he was looking for") found that was decent (you're not allowed to take stuff from the cliff itself, besides being illegal there's also a shitload of rock above you ready to collapse, which is why the beach is closed in those sections), mostly lifting up rocks and digging around in the sand. Pretty small, but there were quite a few people there before us and stuff doesn't always wash up (usually a good nor'easter has to go through, there's videos online of people just picking up big ass megalodon teeth right off the sand after storms).
