trilobite is Bathynotus keuichousensis, the patronymic genus of
the trilobite family Bathynotidae, a family whose ordinal status
was in dispute. The members of the genus have recently been assigned
to the family Chengkouaspidae, a family within the Redlichiida.
Trilobites from this timeframe were members of the Redlichiida,
Ptychopariida, Corynexochida, and the Agnostida, with the balance
of the orders appearing later in time.
