Yesterday there was news of a 3.3 million year old Australopithecus afarensis fossil from Ethiopia. I’m just curious as to how they ascertain the age. I know it’s not carbon-14 dating, that’s 2 orders of magnitude beyond its range. It’s been a while since I learned about this stuff, so thanks for refreshing my memory.
