Discovering Fossils 09-30

Description
 Tectonic activity induces nearby sediment to mobilise, burying the fish in the event.
Rapid burial is a common component for optimal fossilisation, as prolonged exposure would otherwise increase the likelihood of disturbance from scavengers and/or currents. Burial may also occur quickly if a high volume of sediment is deposited in the area following a period of heavy rain that delivers sediment from major rivers (for example).
