  Trace Fossils and Behaviour

Trace fossils provide palaeontologists with information about what the animal was doing at the time it made the trace (this is called animal behaviour).

Trace fossils are formed exactly where they happened - they cannot move from the place in which they were created. Because of this, trace fossils also tell palaeontologists about the ancient environment in which the animal lived.

  The types of animal behaviour can be broken up into six broad groups:

Dwelling: the animal built the trace and then used it as a home.

Resting: the animal simply "took a break".

Feeding: the animal made temporary burrows that it stayed in while it was feeding.

Farming: the animal made burrow systems that have regular patterns. The animal lived in the burrow permanently and farmed for food.

: trackways and trails made by animals "on the move" - traveling from one place to another.

Escape: the animal was trying to escape its home and moved up or down in the sediment very quickly.
