A new compound skeletal organism from the Rosella Formation (Lower Cambrian), Atan Group, Cassiar Mountains, British Columbia

Univ. Toronto, J. Tuzo Wilson Res. Labs., Mississauga, ON, Canada

A new organism, Rosellatana jamesi n. gen., n. sp., has been found in the Lower Cambrian (Bonnia-Olenellus Zone) Rosella Formation (Atan Group) exposed in the Cassiar Mountains of northern British Columbia. The organism produced a compound cerioid skeleton comprising regular to rounded polygonal tubes without tabulae but with up to two septalike vertical partitions; these probably were used in axial bipartite division. The skeleton is similar in important respects to some Ordovician skeletal Zoantharia. As a result, the fossil is assigned tentatively to the Zoantharia within the Anthozoa.--Modified journal abstract.
