Kootenia

Kootenia is a genus of trilobites of the family Dorypygidae. 118 specimens of Kootenia are known from the Greater Phyllopod bed, where they comprise 0.22% of the community.^[1] Its major characteristics are that of the closely related Olenoides, including medium size, a large glabella, and a medium-sized pygidium, but also a lack of the strong interpleural furrows on the pygidium that Olenoides has.^[2]

Synonyms

Kootenia is sometimes believed to be a junior synonym of Olenoides due to the marked similarities, and the fact that the main difference between them seems to be variable.^[3]
