1 E15 s
From Wikipedia, the free encyclopedia
To help compare orders of magnitude of different times this page lists times between 1015 seconds (a petasecond) and 1016 seconds (32 million years and 320 million years) See also times of other orders of magnitude.
- Shorter times
- 34.7 million years -- half-life of niobium-92
- 36 million years -- time since end of Eocene Epoch and beginning of Oligocene Epoch; age of the Cercopithecidae (Old World primates) superfamily.
- 40 million years -- estimated period of time until Australia will collide with Asia; time since the age of the Catarrhini parvorder.
- 65 million years -- time since Cretaceous-Tertiary extinction event at end of Cretaceous Period (end of Mesozoic Era) and beginning of Tertiary Period (beginning of Cenozoic Era); age of the Haplorrhini suborder.
- 135 million years -- time since end of Jurassic and beginning of Cretaceous Period.
- 195 million years -- time since end of Triassic and beginning of Jurassic Period; time since the appearance of the earliest mammals.
- 225 million years -- time since end of Permian Period (end of Palaeozoic Era) and beginning of Triassic Period (beginning of Mesozoic Era).
- 250 million years -- Galactic year - a revolution around the center of the Milky way of our Sun and the Solar system.
- 280 million years -- time since end of Carboniferous and beginning of Permian Period.
