Ichnofacies can provide information about water depth, salinity, turbidity and energy. In general, traces found in shallower water are vertical, those in deeper water are more horizontal and patterned. [1] This is partly because of the relative abundance of suspended food particles, such as plankton, in the shallower waters of the photic zone ...Paleodictyon (Squamodictyon) are rare. The trace fossils were collected or observed at 17 different localities and represent assemblages belonging to the Nereites ichnofacies (deep-sea flysch deposits with thinly bedded turbidites).The name Paleodictyon refers to these strange honeycomb-like constructs produced by an unknown organism. Fossils like this are known from Precambrian rocks over 540 million years old, and scientists STILL find Paleodictyon on the ocean floor today, making the mystery creators true living fossils.

Paleodictyon is an important trace fossil characterised by a regular hexagonal structure and typical of ancient deep-ocean habitats as far back as the Ordovician. It is represented in modern deep-sea settings by Paleodictyon nodosum, known from the Mid-Atlantic Ridge, the South Atlantic, and off eastern Australia.
