Charniodiscus concentricus

Discussion

This species is named on the basis of 12 disc-like impressions from this single locality, found on multiple bedding planes. The author discusses at length the possibility that Charniodiscus concentricus could be the basal disc of Charnia masoni (first described in the same publication), and figures this possibility in a reconstruction (p. 212, Pl. 13, fig. 3). The author concludes "It is concluded that Charnia masoni may most rationally be interpreted as an algal frond and that Charniodiscus concentricus may be the basal part of the same alga.... The only likely alternative is that they represent a primitive coelenterate of unknown affinity".
