These deposits were reworked by wave currents and were affected by burrowers
as it is evidenced by the wave ripples and the Thalassinoides-like traces observed at the tops of the sandstone beds.

Dr Marcello Ruta of the University of Lincoln, with colleagues from the Field Museum of Natural History in Chicago, the Museum fur Naturkunde in Berlin and the University of Bristol, found that near the end of the Permian, a large number of anomodont species existed with a wide range of body sizes and ecological adaptations, including terrestrial plant eaters, amphibious hippo-like species, specialized burrowers
, and even tree-dwelling forms.
