Not to be confused with the evolutionary term derived.

A derived fossil is a fossil found in rock made later than when the fossilized animal or plant died:[1] it happens when a hard fossil is freed from a soft rock formation by erosion and redeposited in a currently forming sediment deposit. Another name for such a specimen is a reworked fossil.[2]
