C. auriculatus is usually placed within the Carcharocles
some researchers think that a placement within the Carcharodon
would be more correct. This debate has been on-going for quite a
considerable time and also includes Carcharocles
chubentensis and even the famous C.
simply to as Megalodon). All of these shark
species are often
referred to as the 'megatoothed sharks' because of their large
sizes and triangular serrated teeth. It is this superficial
similarity with the teeth of the great white shark that we know today
that had them originally placed within the Carcharodon
closer study of the teeth has discovered several differences between
the megatoothed sharks and the great white. Strong evidence for both
placements exists, and to which genus the species belong to is often
down to how an individual researcher interprets the available fossil
Although the teeth of C. auriculatus are mostly known from South Carolina, it may have still had a more cosmopolitan distribution like other megatoothed sharks. Size estimates for C. auriculatus are not common place but as a 'megatoothed shark' it was likely to have been considerably larger than a modern great white, perhaps approaching nine meters in length like its presumed ancestor Otodus obliquus.
