Species
Cochlichnus anguineus Hitchcock, 1858
Taxon description
Gibert & Ekdale, 2002
Tracemaker. Cochlichnus has been interpreted as a locomotion or grazing trace (Buatois et al., 1997). It has been traditionally suggested that the most likely producers of this trace are nematode worms (Moussa, 1970), although Gluszek (1995) proposed a longer list of potential tracemakers, including also annelids, nematomorphs, dipterous insect larvae and cyclostome agnathans.
