Found many shark teeth in South Carolina and Florida decades ago. Identification of the teeth has always been a challenge, even today, trying to use available charts to identify these 3 is difficult (for me). Knowing TFF has many shark enthusiasts, this should be a cakewalk. These teeth are from a Miocene bone bed, Astoria Formation, Washington state. Found scattered in the matrix surrounding cetacean bones, otolith, fish scales, Calionopsis claws and carbonized wood. Thanks for the help! Oh, these are 1/2 - 3/4 inches.
