This is just a holding page for now.

The Mesoarchean is a geologic era within the Archean, spanning 3200 Ma to 2800 Ma (million years ago). The period is defined chronometrically and is not referenced to a specific level in a rock section on Earth. Fossils from Australia show that stromatolites have lived on Earth since the Mesoarchean. The Pongola glaciation occurred at 2.9 Ga. The first supercontinent Vaalbara broke up during this time around 2.8 Ga. -- Wikipedia
