Using larger benthic foraminifera for the paleogeographic reconstruction of Neo-Tethys during Paleogene

摘要

The biostratigraphic range distribution of larger benthic foraminifera (LBF) from the eastern part of Neo-Tethys in the Kohat Basin of Pakistan is compared with the Western and Central Neo-Tethys. The results are used to establish the migration pathways of LBF for the paleogeographic reconstruction of the Neo-Tethys that existed in the Paleogene. This comparison across the Neo-Tethys revealed that LBF species are mostly confined to the Gondwanan (Iran, Iraq, Pakistan, India, Indonesia) and Laurasian-derived blocks (Italy, France, and Spain), with only a few on the margin of the Gondwanan continents (Oman).
