- Great A’Tuin (Wikipedia)
Great A’Tuin is the Giant Star Turtle (of the fictional species Chelys galactica) who travels through the Discworld universe’s space, carrying four giant elephants (named Berilia, Tubul, Great T’Phon, and Jerakeen) who in turn carry the Discworld. The narration has described A’Tuin as “the only turtle ever to feature on the Hertzsprung–Russell diagram”.

The Statherian Period ( /stəˈθɪəriən/; Ancient Greek: σταθερός, romanized: statherós, meaning “stable, firm”) is the final geologic period in the Paleoproterozoic Era and lasted from 1800 Mya to 1600 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.
