Ectasian (Wikipedia) The Ectasian Period (from Ancient Greek: ἔκτασις, romanized: éktasis, meaning “extension”) is the second geologic period in the Mesoproterozoic Era and lasted from 1400 Mya ago to 1200 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.
