Temporal range: Burgess Shale
Conway Morris, 1993
Thaumaptilon is a fossil genus of animals from the middle Cambrian Burgess Shale which some authors have compared to members of the Ediacaran biota, generally believed to have disappeared at the start of the Cambrian, . It was up to 20 cm long, and attached itself to the sea floor with a holdfast.
Leaf-shaped, Thaumaptilon had a central axis extending to its tip, with many "ribs" radiating from it, in a similar manner to the ribs of a leaf. these may have had canals connecting them to the axis. One side of its surface was covered in spots, which might have been zooids.
