Colorful Great White Ancestor Mako Shark Isurus escheri 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 has serrations present, it is not the other known fossil Mako shark Isurus hastalis. 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 coloration. This one comes in a 139 mm by 114 mm display box, making it a fine presentation specimen.
