Colorful Great White Ancestor Mako Shark Tooth

Description: This is a fine example of a tooth from the extinct Mako shark Isurus escheri . These sharks are thought to be the progenitors of what was to be Carcharodon carcharias, the Great White. Due to the fact that it does not have serrations present, it is not the other known fossil Mako shark Isurus escheri. This one has a RAZOR SHARP edge, very important for this predator’s ability to slice flesh off its prey. Teeth are highly variable in color, a consequence of the minerals in the water that formed the deposits. This one has a most pleasing pink and beige coloration. Given the rule of an inch of tooth equals 10 feet of shark, this one came from a mako some 24 feet in length. It comes in a fine Riker-type display box.
