ABSTRACT
Ichnology is finding major application in the descriptive logging of cores. Some of this material derives from the exploration of the ocean floor in the form of piston cores, vibracores, box cores and can cores, including the copious material of the Deep-Sea Drilling Project and Ocean Drilling Project. Still more demanding is the material provided by cored wells of oil companies. In the often hasty and impatient atmosphere of the core laboratory, kilometres of costly core are at this moment receiving inadequate attention from far too few, overworked, specialist geologists. All but two of the photographs illustrating this chapter were taken by me under such conditions, while working on Jurassic cores from the Norwegian sector of the North Sea.
