Geological Time Scale

The geological time scale summarizes the divisions of geological time.  It is based mainly on the extinction and evolution of life forms, but also the changes of the earth's land surface and oceans.  The time scale has been in use for about two hundred years, but the numbers dates in millions of years have been known for less than one hundred years, and are being continually improved and better understood. 

To learn about the Geological Time Scale and the Earth's fascinating geological history, go to this web site.

To memorize the order of geological periods (one of the first things geology students must memorize) you can use mnemonics.  You will find many choices of good mnemonics at this web site.

To memorize the numbers in the time scale, you can use Pseudonumerology.  You need to find a pseudonume that you can associate with each of the periods.  In the short list below, I have used the Ponderous Pseudonumer® to find pseudonumes for the main numbers of the 1982 time scale. 

(If you just found this page directly from the internet and still don't know what a pseudonume is, you must go back to the home page, Pseudonumerology.com and read about it.  Then learn to pseudospell, which takes a few minutes, before returning to this page.)

Arabic numerals:  

Beginnings of the periods in the 1982 Geological Time Scale
Period  Age  Pseudonume How the pseudonume can be remembered
Tertiary    66 m.y.  Ouch-ouch!  the dinosaurs suddenly become extinct.
Cretaceous  145 m.y.  T-rule  Tyrannosaurus (T-Rex) rules in the end of the Cretaceous
Jurassic  208 m.y.  No safe  no one is safe from the meat-eaters.
Triassic  245 m.y.  New role  the dinosaurs appear and lead a new role in evolution
Permian  290 m.y.  Knobs  knobs of Permain rocks stand up in the Oslo area
Carboniferous   362 m.y.  Matchin'  Carboniferous (coal) is lit by "matching" with a lighted match
Devonian  408 m.y.  Erosive  erosive forces dominate the Devonian
Silurian  439 m.y.  Ramp  the Silurian strata are characterized by ramp structures
Ordovician  510 m.y.  Lots   the Ordovician rocks in Norway contain lots of fossils
Cambrian  570 m.y.   Legs  in the Cambrian period the first animals with legs appeared

Since 1982, the time scale has been much improved.  The ages are now more precisely defined, by analyses of radioactive rocks that were collected from the borders.  These new precise dates for periods, epochs, and ages should really be known by geologists who are working with rocks of these periods. 

Pseudonumes for remembering the beginnings of the epochs
Based on the time scale of Gradstein & Ogg, in Episodes v.19, no. 1 & 2 1996:
