The proto-Creeperian civilization lasted from 2500 BC to 250 BC. The period is divided into three eras:
- Inalikauitl (Early Period)
- Ueykauitl (Great Period)
- Tsakikauitl (Late Period)
The period was succeeded by the Creeperian Dark Age (250 BC – 220 BC), and then by the Creeperian Confederation (220 BC – 537 AD).
