Extinct Tiger Shark Age - Eocene Commonality - Very Uncommon(?) First appearing in the Eocene Galeocerdo
latidens is considered the oldest of the tiger sharks. These teeth
are small, averaging ¼ inch when measured on the diagonal. At first
glance these teeth may easily be mistaken for a small
Galeocerdo aduncus,
a common find in New Jersey. Besides size, G. latidens differs
from G. aduncus in two obvious areas, a lack of serrations on the
mesial coronal apex (tip of the crown) and more importantly
the presence of simple rather than complex serrations on the
distal shoulder.
Galeocerdo latidens teeth are small
