Water lily Scutifolium jordanicum, marsilealean fern Marsileaceaephyllum mahisensis and tree fern Weichselia reticulata are from a thin crevasse splay layer of a small fluvial system.

Phlebopteris hickeyi represents a new fern species that has five preserved pinnae with unique characteristics, including small sori and sporangia. The relatively small pinnules with massive midveins and grooves along either side of midveins represent a unique combination of characters. The water lily S. jordanicum and marsilealean fern M. mahisensis may have grown in ponds, lakes or slow-m...
