The trace fossils of the Baggy Beds (Upper Devonian) of North Devon, England

The trace fossils of the Baggy Beds are described. They include Teichichnus cf. rectus Seilacher, Monocraterion cf. tentaculatum Torell, Diplocrateflon yoyo sp. nov., Arenicolites curvatus sp. nov., and other forms insufficiently well preserved for generic assignment. The protrusive and retrusive behaviour pattern of D. yoyo is interpretated as a response to repeated phases of sedimentation and erosion and as a measure of these. A. curvatus is preserved in two modes: in the position of formation and as eroded tubes in conglomerates. The second reveals that the sediment around the tube was cemented to a thickness equal to the diameter of the tube.
