In this paper, 4 ichnogenera and 4 ichnospecies have been identified in Taishanmiao Formation. The paper especially discusses the developing features of the Beaconites coronus in different microfacies, and speculates that the trace-makers of Beaconites adapt best to the shore lake environment. espace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
