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. 
Lower lateral Notorynchus cepedianus fossil shark tooth 


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