Phylogenetic analysis suggests that the corystosperm cupule is an unlikely homologue for the angiosperm carpel or outer integument, and studies that treat Dicroidium leaf morphospecies as proxies for biological species of entire plants should be reconsidered.

Analysis of the new Texas fossils refutes or seriously challenges many widely accepted hypotheses regarding the biogeography, structure, and paleoecology of F. ramosissima, which can no longer be considered a Potomac Group–endemic taxon.

The oldest definitive records for three orders of insect and numerous families and super families are reported, and the flora is shown to contain an unusual diversity of forms, some of which have only been previously reported either from Europe or the Southern Hemisphere.

Owing to the large amount and often exquisite preservation of the material, this conceptual whole-plant genus represents one of the most completely reconstructed ancient conifer taxa to date.

The Triassic age of this fossil is consistent with the basal or near basal position of the Hymenophyllaceae in all recent phylogenetic analyses of the filicalean ferns.

The ovule-bearing leaves now known as Spermopteris coriacea are proposed to be named as a new species of Phasmatocycas, which is less cycad-like than previously thought, and the phylogenetic position of the genus is unclear.
