It was formulated in 1669 by Nicolaus Steno.
The Full Story
The law of superposition states that in a sequence of sedimentary rocks that has not been overturned, the oldest layers are at the bottom and the youngest are at the top. Nicolaus Steno set out this principle in 1669 while studying rock strata and fossils. It became one of the most important tools for relative dating in geology. Even today, it helps geologists interpret the order of events recorded in layered rocks.
