  1. The India-Asia Collision and Exchange of Terrestrial Fauna

  2. Background • The Early Eocene • Specifically between 52-55 ma • Type of Organisms • Dinoflagellates, Mollusks, Fish ooliths, • Modern Mammals: Artiodactyls, Perissodactyls, Primates.

  3. Environmental Changes • Tectonic movements pushed India into Asia ( 54ma ) • Created brackish water between the two land masses. • Allowed for organisms to cross once India made contact. • A series of warming events occurred starting with the most influential:Paleocene-Eocene Thermal Maximum 55.5ma. • Greenhouse conditions • Warmer climate

  4. Life Adaptations • Organisms had to adjust to the less saline water as the sea between them closed in. • A “land bridge” allowed for the migration of organisms out of India. • PETM’s warmer temperatures required these organisms to adapt further.

  5. Other Interests • Analyses of carbon and strontium isotopes • Fossil record shows migration out of India
