It is believed that the Shujiaba Formation belongs to a series of thic
k turbidites. 20 ichnogenera have been found in the formation, of whic
h 14 genera were found in the Devonian System of China for the first t
ime. The ichnogenera are mostly of typical deep-water ones and belong
to the Nereites ichnofacies. A detailed study of morphology and behavi
our of the trace fossils indicates that the Shujiaba Formation was dep
osited in a bathyal-abyssal environment.
