kiangsuaspis nankingensis is an extinct phyllocarid crustaceans from late silurian china. it was originally described in 1962 by kiang p'an as an incomplete ventral plate of a cyathaspidid heterostracan agnathan with a unique pattern of raised, sculptured tubercles that fuse together into anastomosing ridges. in 1984, jiang p'an then reappraised it as a ceratiocaridid crustacean.
