Abstract

Specimens of the discoid, chambered megafossil Kullingia delicata (Fedonkin) occur near the base of member 2 of the Chapel Island Formation on the Burin Peninsula of Newfoundland. Morphologic and taphonomic features suggest that these fossils can be interpreted as the impressions of pelagic chondrophorines. Kullingia provides a link between Ediacaran and Paleozoic forms, and thus supports the view that the Chondrophorina represents a conservative evolutionary lineage extending back into the Precambrian.
