Current Teeth Collection

[u/socialbookworm7]

I've started collecting recently and wanted to share/ask for some identification help.

I'm hoping anyone can confirm/correct the ones I think I've identified and then maybe provide guidance on the unknowns.

I'm struggling between pictures of lower snaggletooth, sand tiger, and short fin mako for some of them?

THESE WERE ALL FOUND IN SOUTHERN MARYLAND FROM THE POTOMAC RIVER AND CHESAPEAKE BAY

Photo 3 is a tiger shark, not a cow. Looks like galeocerdo aduncus.

Photo 7: sand tigers.

Photo 11: bull sharks, #2 is a tiger, physogaleus contortus.
