Partial skull

This well-preserved fossil is the only intact partial skull ever found of a white shark that lived about 4.5 million years ago. In a new University of Florida study appearing in the Nov. 14, 2012, issue of Palaeontology, the species was named Carcharodon hubbelli for Gordon Hubbell, who donated the fossil to the Florida Museum of Natural History on the UF campus. The fossil jaw contains 222 teeth, some in rows up to six teeth deep.
