Found on N Topsail Beach, NC, in October of 2015 (not long after a dredging and sand replacement project). Longest edge is 6 cm.
Various "authorities" have offered conflicting id's. I don't have many fossils worth showing anybody and I'd like to be able to tell visitors definitively what it is.
I did read the various threads on this topic in the forum and looked it up in other sources, as well. However, I found researching Carcharocles auriculatus vs Carcharocles angustidens much like watching a pack of hound dogs turned loose on a truckload of rabbits released in the forest.
Would appreciate opinions from those knowledgeable on the current theories regarding this (apparent) debate. Or is it just evolution of opinion?
