Colorful Great White Ancestor Mako Shark Fossil 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. 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 gray coloration.
