We argue that this HVA is corresponding with the suture zone associated with the Mesozoic ECS and SCB collision between ~150 Ma, which is about 100 km from the coastline. Geologic TimelineLast updated September 24, 2025 Timeline of Geologic History ("mya" is Million Years Ago; "bya" is Billion Years Ago) Unfortunately, knowing how to express geological time doesn’t really help us understand or appreciate its extent. This timeline of Earth's history summarizes significant geological and biological events from the formation of the Earth to the arrival of modern humans. ” Ma’am the confidence 😭 She didn’t even ask for the price!
