Extract

The ichnogenus Didymaulichnus has previously been reported in rocks of upper Precambrian-Carboniferous age (Häntzschel, 1975; Pickerill et al., 1984). Didymaulichnus has been postulated by different authors to be an epistratal grazing trace of trace makers ranging from molluscs and other soft-bodied animals to arthropods (Young, 1972; Häntzschel, 1975; Bradshaw, 1981; Hakes, 1985). If this is the case, it is reasonable to assume Didymaulichnus occurs in sediments and sedimentary rocks that are as young as the modern. In an examination of the Cardium Formation (Upper Cretaceous, Turonian) this ichnogenus occurred with relative abundance.
