Gomphotherium land bridge
The Gomphotherium land bridge was a land bridge that connected Eurasia to Afro-Arabia between approximately 19 Mya (million years ago) and 15 Mya.[1]
Significance
Passage of fauna between
tectonic plates of Afro-Arabia and Eurasia collided, creating a terrestrial isthmus
connecting the two landmasses.
This faunal exchange that resulted is known as the Proboscidean Datum Event.[1]
The land bridge allowed the elephantine proboscideans to migrate out of Africa and into Eurasia.[2] It is believed that the connection between the Mediterranean and Indian oceans was temporarily re-established during the Langhian stage of the Middle Miocene, before reclosing, and has remained closed to present day.[1]
