The flora known from the Stonesfield Slate comprises a relatively diverse flora, with 25 morphospecies present. It primarily represents a coastal environment, perhaps seasonally dry with mangrove like environments. It is a noticeably different assembelageassemblage than the Yorkshire floras of equivalent age, possibly because the latter is thought to represent a deltaic, wetland environment.<ref>{{Cite journal|lastlast1=Cleal|firstfirst1=C.
