An epoch is one of the smaller divisions of geologic time. Our current epoch, the Holocene, began about 11,600 years ago. But there is evidence that we are entering a new epoch that could be named the Anthropocene because it is marked by extensive human impacts on the environment. This poster explores evidence that future geologists might use to define the Anthropocene.
