Divergence time estimates of mammals from molecular clocks and fossils: Relevance of new fossil finds from India.

This paper presents a brief review of recent advances in the classifi cation of mammals at higher levels using fossils and molecular clocks. It also discusses latest fossil discoveries from the Cretaceous – Eocene (66–55 m.y.) rocks of India and their relevance to our current understanding of placental mammal origins and diversifi cations.
