Oryctocephalus is a genus of trilobite known from the Middle Cambrian Burgess Shale. 24 specimens of Oryctocephalus are known from the Greater Phyllopod bed, where they comprise 0.42% of the community. [1] This small- to medium-sized trilobite's major characteristics are prominent eye ridges, pleural spines, long genal spines, spines on the pygidium, and notably four furrows connecting pairs of pits on its glabella. [2] Juvenile specimens have been found with only 5 or 6 thoracic segments and about one eighth of adult size, as well as about 2 mm wide. [3]
