>Will our influence on the rock record really be so profound to geologists 100 million years from now, whoever they are, that they would look back and be tempted to declare the past few decades or centuries a bona fide epoch of its own? Yes, there will be a thin but noticeable layer of hydrocarbons and odd pollution signatures in the crust that will act as a permanent geologic record of our existence. |

If you were specifically looking for it.
Somebody might notice a lack of elephant teeth above a peculiar boundary, or a reduction in fish bones and corals, and look closer at the boundary. But to notice a lack is much harder than to notice the advent of something new. A layer of paperclips might not attract much attention, once oxidized, or be interpreted with anything like fidelity.
