Alopias subexigua is an extinct species of thresher shark, that lived in the Eocene to Miocene. It is known only from teeth. Alopias subexigua was discovered in North America, in California,[1] Asia,[2] Portugal, and Africa.[3]
Classification
The classification of A. subexigua is in debate, as is the case of most sharks. A. subexigua is a related species to the also extinct Small or Modest Thresher shark (Alopias exigua), whose fossils are very similar to genus Isurus. A. subexigua is placed in the family Alopiidae.
