Ichogenus	Topo	Morphology	Nature of Fill	Ethology
Bergaueria	HR	rounded pits, cms in diameter and depth, unlined	Same as overlaying unit	Resting or Drewlling
Chondrites	FR (SR)	regular, root-like branching burrow system, tunnels of uniform diameter, mm-scale, unlined	Mud fill in sand host or sand fill in mud host	Feeding
Cruziana	HR	v-shape(bi-lobed), furrow with scratch marks	same as overlaying unit	crawling or grazing
Cylindrichnus	FR	vertical to inclined, concentrically lined, flares upwards, never branch	tube usually filled with massive sand	Dwelling
Diplocraterion (bad images, to be replaced)	FR	vertical U-shaped, spreiten borrows, “3D”	tubes filled with massive sand	Dwelling
Entobia	FR (SR)	very small sharp-walled/tunnels, usually found on calcareous shells	unfilled, sediment or cement	Dewlling, Feeding
Helminthopsis	FR (SR)	horizontal to inclined, sometimes branched, J-shape hooks and arcs, mm-size	Usually mud fill in sand host	Feeding or Grazing
Macaronichnus	FR (SR)	horizontal to inclined, rarely branched tunnels that almost never overlap or touch, lining is caused by the qz-rich sand core and lithic-rich outer core	sand fill in sand	Feeding
Ophiomorpha	HR	“poop”-like, cm-scale, vertical, inclined – horizontal borrow system, lined with agglutinated pelletoidal sediment/fecal pellet mixture, “Y” or “T” shaped branching	usually sand fill (same as host)	Dwelling
Palaeophycus	FR (SR)	horizontal tunnels, never branch, think mud lining, often small scale and can cross over	same fill as host	Dwelling
Phycosiphon	HR	un-branched, light coloured halo(too small to see), mm-scale, horizontal to inclined, J-shaped/hooks	mud fill silty halo	Feeding or Grazing
Planolites	FR (SR)	overlapping horizontal tunnels, unlined, sometimes branching, , looks like palaeophycus, but sinusoidal	Mud fill in sand or sand fill in mud	Feeding
Rhizocorallium	FR (SR)	horizontal to inclined burrow with spreite, unlined or sometimes thin mud lining	Tubes filled with massive sand, “2D”(horizontal to bedding)	Feeding or Dwelling
Rusophycus	HR or ER	bi-lobed, round, oval to heart shaped, shallow pits with scratch marks, lava like lumpy	Same as overlaying unit	Resting
Skolithos	FR	vertical to inclined shaft, sharp walled, sometimes thinly mud lined	tube usually filled with massive sand	Dwelling
Teichichnus	FR	horizontal to inclined tube upward-migratied to produce spreite, unlined, never branched	alternating sand/slit/mud (massive sand)	Feeding or Dwelling
Teredolites	FR	cm-scaled tunnels/shafts or club shaped burrows, sharp walled, never branch, never overlap, small bumps	sand fill in with woody or coal material	Dwelling or Feeding
Thalassinoides	FR	cm-scale, Y or T shaped branches, horizontal to inclined vertical burrow system, smooth/sharp wall, unlined or very thin mud lining	usually sand fill in mud (different from host)	Dwelling or Feeding
Zoophycos	FR	fan like circular shape, flat, curved or inclined, spreite in the xsection, causive burrow is cm-scale vertical shaft	alternating mud fill, sand and poop	Feeding or Grazing
