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
• 40 million years -- Estimated period of time until Australia will collide with Asia
• 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)
• 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
• 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 Milky way of Sun and the Solar system.
• 280 million years -- time since end of Carboniferous and beginning of Permian Period
• Longer times
