Traces of ancient organisms (plant or animal) typically found in sedimentary rock, preserved for a long period of time.

Fossils

300

The smaller group of galaxies containing the Milky Way

This principle describes the phenomenon of fossil succession whereby the oldest fossils are found at the bottom of stratigraphic layers and the newest are found at the top.
