Great white shark evolution (Isurus hastalis -> Carcharadon hubbelli -> Carcharadon carcharias) -

This is my updated Great White "Evolution Collection". The fossilized teeth are between 2.7 and 2.9 inches in length and all are from Chile except mako from Sharktooth Hill. From left to right they include a 2.7" inch Broad tooth mako (Isurus hastalis), then 2.8" GW transition tooth (C. hubbelli) , then another 2.7" GW transition tooth (C. hubbelli), then 2.9 inch fossilized GW tooth (C. carcharias), and finally a 2.3" Modern day Great White on the right.

This is set of teeth is an example of a commonly accepted evolution of the modern day great white shark from ancient makos, though other theories of the evolution are out there. Of interest to anyone who is unfamiliar, look closely at the complete lack of serrations on the broad tooth mako on the left; then variable degree of fine serrations on the two transitional teeth (recently classified as "C. hubbelli"), and finally the fully serrated fossilized and modern day great white teeth on the right.
