Gomphotherium land bridge

The Gomphotherium land bridge was a land bridge that connected Eurasia to the Arabian Plate approximately 19 Mya (million years ago).[1]

Significance

Passage of fauna between Eurasia and the Arabian Plate was largely hindered before the Early Miocene, as animals could not cross the open Tethyan seaway. However, during the mid-Burdigalian, the 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 Gomphotheres to leave Africa.[2]
