Cenozoic Eras

Origins

First proposed by the

Indochina.[2][3]

As envisioned, the ATG had a wide distribution when the global climate was much warmer than it is currently, a situation strengthened by the closer position of some of the continents in late Mesozoic to early Cenozoic times.

subtropical species were left in isolated pockets of warmer climates.[6]

The southern, more tropical equivalent of the ATG was the Neotropical Tertiary Geoflora.[a][6]
