Ceratophyton

This species, the type, comprises a single unornamented cone.^[1] This species occurs in platform settings in western Russia in the Lontova and Lyukati horizons, first occurring in the local base of the 'Cambrian'.^[2][6] In Poland it occurs from the base of the Cambrian (Platysolenites zone) to the Schmidtiellus zone.^[6]

It has been reported from the middle Cambrian of Belgium, although these specimens are short on diagnostic features.^[3]

It also occurs below the T. pedum zone, indicating the presence of the producer in the Ediacaran period.^[7]

This species is represented by single cones that have rings around their bases.^[1]

This taxon has a double wall, resembling a pair of stacked cones; it may represent a taphomorph of C. vernicosum.^[2]

This single cone has short conical spines, which occur on its basal region.^[1] This species is known from the mid-to-late Atdabanian siltstones of the Ouldburra formation of Australia.^[7][8]

This species again comprises a single cone; it has spines and processes along both margins.^[1]

Ceratophyton differs from the taxon Veryhachium in having a basal opening.^[2]
