The upper discoid-bearing bed varies from 1-8 cm thick and bears Arenicolites, Palaeophycus, Planolites, and Rusophycus (bbi: 3, ii: 1), as well as ~8 cm wavelength, 1.5 cm high, straight- to sinuous-crested, mud-draped oscillation ripples.

In contrast, Bromley and Asgaard (1991) suggested the presence of the Arenicolites ichnofacies where similar, but more diminutive morphologies are present, and where the vertical aspect burrows do not overprint one another.
