Fossil Sharks of Panama
The Panama isthmus was formed about 3.1-2.8 Ma, is a narrow strip of land that separates the Caribbean Sea and the Pacific Ocean. Before the isthmus arose, the two oceans coexisted in that area forming the Central America Seaway. The fossil record indicates that in the past, different shark species inhabited this seaway. Several changes in oceanographic conditions associated with the geologic processes of the formation of the isthmus had different effects in shark fauna.
