To help compare orders of magnitude of different times this page lists times between 1016 seconds (320 million years) and 1017 seconds (3200 million years). See also times of other orders of magnitude.
- Shorter times
- 340 million years—time since the beginning of the Carboniferous and the end of Devonian period
- 400 million years—time since the beginning of the Devonian and the end of the Silurian period
- 420 million years—time since the first creature took a breath of air
- 435 million years—time since the beginning of the Silurian and the end of the Ordovician period
- 500 million years—time since the beginning of the Ordovician and the end of the Cambrian period
- 540 million years—time since the beginning of the Cambrian and the end of the Precambrian period. Time since the Cambrian explosion and age of the earliest Vertebrates.
- 575 million years— age of the oldest Animal fossils
- 580 million years—time since the end of a possible Snowball Earth ice age
- 600 million years—age of first complex multicelled lifeforms
- 703.8 million years—half-life of uranium-235
- 750 million years—time since the beginning of a possible Snowball Earth ice age
- 1277 million years—half-life of potassium-40
- 1.8-2.1 billion years—age of the earliest Eukaryotes
- 2.3 billion years—time since the first known ice age
- 3.0 billion years—time until the potential collision between the Milky Way and Andromeda galaxies
