The presence of a palaeosurface with a set of relatively large concave epirelief tracks that extend for some 60 m is documented and described. The trackmaker is believed to be a member of the genus Aulacephalodon Seeley 1898 or Rhachiocephalus Seeley 1898 and to have walked across a submerged silty surface on a floodplain. A mud veneer deposited under relatively low energy conditions soon after the tracks were made, and the thermal alteration of the sediment by nearby diabase intrusives, contributed to the preservation of this set of fossil tracks.
