my added if correct. I would like more information such as upper or lower and which side is showing. Is this an extinct great white shark and type? 

large 1 3/8th in. long small 1 1/16th inch

This is a 1 3/8th inch long, nicely colored tooth of Isurus hastalis, 
an extinct giant mako shark.

PELECYPODS is this a Fossilized giant clams. Cucuillaea gigantea or a Large fossil clam steinkern? At the tailgate show.

Pretty sure the larger tooth is an Otodus since it has a bourlette. Hawthorne Formation was Otodus angustidens right? Don't quote me on that though.

my search info. Notorynchus cepedianus tooth identification 
5 five cusp, showing masial side.

I assume that these have been glued to a piece of matrix not necessarily from the location of the teeth?
