Galeocerdo mayumbensis is an extinct species of sharks that lived in the Miocene period. A relative of the tiger shark (Galeocerdo cuvier), it lived in North America, South America, mainland Africa and Madagascar. The teeth of G. mayumbensis are different from those of G. aduncus.

Description

Galeocerdo mayumbensis probably reached the same size as G. artictus. Its teeth are tall and straight, and similar to those of G. latidens, being of the same height. Galeocerdo mayumbensis differs from G. aduncus by having concave rather than convex teeth. It lived alongside Megalodon. G. mayumbensis probably fed on fish, marine mammals, and sea turtles.
