| 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).
