Discovery of the youngest known tommotiid from the middle Cambrian (Drumian) Nelson Limestone of Antarctica
(English)Manuscript (preprint) (Other academic)
A potential fragmentary tommotiid sclerite is described from the Nelson Limestone Formation of the Pensacola Mountains, Antarctica (Drumian in age). The sclerite bears similarities to other early Cambrian camenellan tommotiids. The sclerite is bilaterally symmetrical and may belong toa new genus. The find suggests that tommotiids may range into the Drumian Stage.
