Cenozoic (cainozoic: now, quaternary period (1. 8my-now) holocene epoch (100ky-now) pleistocene (1. 8-0. 1my, neogene period (23-1. 8my) pliocene epoch (5. 3-1. 8my) miocene (23-5. 3my, paleogene period (65. 5-23my) oligocene (33. 9-23my) eocene (55. 8-33. 9my) . Palaeocene (65. 5-55. 8my: australia breaks away from antarctica and drifts north, crossing climate zones. ), mammals begin to take over world, flightless birds, horned turtles, snakes, crocodiles and frogs around. Australia late miocene (8my: australia beginning to collide with asia, forming island arc, australia dries out, as polar ice sheets grow over antarctica, rainforests draw back to coastal areas, megafauna diprotodo(cid:374)tids, hoppi(cid:374)g ka(cid:374)garoos, (cid:862)thu(cid:374)der (cid:271)irds(cid:863) (cid:894)bullo(cid:272)kor(cid:374)is(cid:895) Sea levels drop, exposing the nullarbor plain carbonates above sea level. Australia pliocene (4my: australia close to present position, as has collided with south asia, australia alternating between warm and wet, and drying out, eucalypts and wattle trees dominate forests, giant python (wonambi 10m long), previous animal groups persist. Rats and mice migrate in from south east asia.
