The Apex Chert fossils date from this geologic unit of time.
The Apex Chert fossils date from this geologic unit of time. Zircon deposits at the Jack Hills in Western Australia give credence to the idea that bolides repeatedly struck earth during it, which is called the Cool Early Earth Hypothesis. The Huronian Glaciation occurred during this section of time, and that event was followed up by the Great Oxygenation Event. Sub-periods of time within this one include the Eoarchean, the Neoproterozoic, and the Hadean, the last of which is its first subdivision. It is the only super-eon that is currently defined and consists of everything before the Paleozoic Era. It ended with the inauguration of a geological era that featured a burst in the biodiversity of life. For 10 points, identify this period of time that was followed by the next period's namesake explosion.
