FIGURE 1 Field techniques in ichnological analysis. (A) Sawn wall in the Babino Quarry south of
the Ladoga Lake, Russia, displaying a Middle Ordovician limestone succession with ichnofabrics in
stained firm- and hardgrounds. (B) Prof. Dr. Adolf Seilacher explaining a casted bedding plane with
Haentzschelinia ottoi as part of his Fossil Art collection exhibited during the 33rd International Geo-
logical Congress 2008 in Oslo. (C) Koji Seike with a plaster cast of a Psilonichnus -like Y-shaped
burrow of the ghost crab Ocypode quadrata from the East Beach, San Salvador Island, Bahamas.

ern North Sea with Arenicolites -like burrows (upside down, up to 3 cm long) produced by the amphi-
pod Corophium volutator . Original from Hans-Erich Reineck, Senckenberg in Wilhemshaven,
Germany. (E) Panels made from pelagic nodular limestone with Thalassinoides -like burrow
networks of the Lower Jurassic Rosso Ammonitico facies, northern Italy. (F) Plaza in a Spanish
Pyrenean village paved with slabs exhibiting Paleogene flysch trace fossils.
Unconsolidated, wet or dry sediment sections can be treated with various
materials such as lacquer, clues, latex, plaster of Paris, resins, etc., in order
to replicate them in the form of a peel ( Kidwell et al., 1985; Skipper et al.,
1998 ). A similar approach allows also for collecting modern surface traces in
