Summary

Scientists note that microplastic particles in sediment layers could help mark the start of the Anthropocene epoch, but their tendency to migrate downward into older layers makes precise dating difficult. This movement complicates efforts to use plastics as a reliable geological time marker.

Plastic particles in sediments could help to pin down the start of a new geological epoch. But their ability to migrate to older layers is muddying the waters.
