Pattern analysis of Paleodictyon and related trace fossils

Graphoglyptid burrows, preserved as erosional casts on the soles of flysch turbidites, represent a seemingly homogeneous group. Preservational effects cli minatcd, their regular and highly diverse patterns rellect the adjustment of a few basic behavioural programmes to diff erent nutritional strategies within the food-restricted, but stable, biotopc of deer-sea muds.
