- ~1.1 billion years ago (Stenian), Siberia became part of the major supercontinent of Rodinia.
- ~750 million years ago (Cryogenian), Rodinia broke up, and Siberia became part of the minor supercontinent of Protolaurasia.
- ~600 million years ago (Ediacaran), Protolaurasia became part of the major southern supercontinent of Pannotia.
- ~550 million years ago (Ediacaran), Pannotia broke up and Protolaurasia split up and became the continents of Laurentia, Baltica, and Siberia.
- ~Cambrian, Siberia was an independent continent.
- ~Carboniferous, Siberia collided with the minor continent of Kazakhstania.
- ~Permian, Siberia, and Kazakhstania collided with Baltica, thus completing the formation of the supercontinent Pangaea. Siberian Traps formed.
- ~Jurassic, Pangaea split up, Siberia stays with Laurasia.
- ~Cretaceous, Laurasia gradually splits up, Siberia remains part of present day northeastern Eurasia.
- ~Present, Siberia was part of forming minor supercontinent Afro-Eurasia.
