253:. It was first identified by Emily Bamforth and Guy Narbonne in 2009. Because its characteristic flexible leaflet structure is dissimilar to other known rangeomorphs, Bamforth and Narbonne describe it as a new rangeomorph form, called hapsidophyllid. The only other known hapsidophyllid is the Ediacaran frond

holotype is 110 mm long and 4 mm wide. It is composed of multibranched leaflets radiating from a single elongate basal rod. The leaflets gradually taper toward their distal ends and overlap one another. This leaf shape points towards a suspension feeding behavior. The overlapping branches

holotype resides in its type locality in the
Mistaken Point Ecological Reserve, and a cast of the specimen is on display at the Royal Ontario Museum in Toronto, Canada.
