, identified it as a new genus. ''Paracharnia'' is a pennatulid within the taxon of Rangeomorpha. It is closely associated with macroscopic algal remains of ''Vendotaenia'' and dense Cambrian shelly fossil deposits, suggesting its paleontological relevance. The original fossil extraction from Ding and Chen (1981) is notable for its distinction from the original ''Charnia'' from Ford (1958) due to the arrangement of each of its polyp leaves and the length of the peduncle. Each polyp leaf in the 1981 recovery is smaller and further out on the stem.
