What is "ovatoryctocara"

Ovatoryctocara is a genus of small corynexochid trilobites from the Cambrian, that lived in what now are Siberia, China, Greenland and Canada (Newfoundland). Ovatoryctocara can be recognised by the combination of the following characters: the central raised area of the cephalon (or glabella) is approximately cylindrical and has two rows of four triangular or round pits. The thorax only has 5 or 6 segments. The tailshield (or pygidium) has an axis (or rhachis) of 6 to 12 rings, the pleural furrows are well developed and the border is absent or narrow as a hair.
