Trypanites is a narrow, cylindrical, unbranched
boring which is one of the most common
trace fossils in hard substrates such as rocks, carbonate
hardgrounds and shells (Bromley, 1972). It appears first in the Lower
Cambrian (James et al., 1977), was very prominent in the
OrdovicianBioerosion Revolution (Wilson and Palmer, 2006), and is still commonly formed today. Trypanites is almost always found in calcareous substrates, most likely because the excavating organism used an acid or other chemical agent to dissolve the
calcium carbonate (Taylor and Wilson, 2003). Trypanites is common in the Ordovician and Silurian hardgrounds of
Baltica (Vinn et al. 2015).
