This week’s Fossil Friday post showcases a hammerhead (Sphyrna sp.) shark tooth. This particular specimen is from the Milwhite Gunn Farm Mine site in Florida, but fossil hammerhead teeth have been found in the Gatún Formation in Las Lomas and the Chucunaque Formation in Lago Bayano. Hammerhead sharks are found worldwide today but are only found in the Caribbean in the fossil record.
