Spongiophyton is an enigmatic Lower to Middle Devonian fossil that has been the subject of much debate since its initial description. The most recent hypothesis based on newly described permineralized material and chemical analysis posits it as the remains of a fossil lichen. Detailed analysis with the SEM is generally supportive of this interpretation. The main structural characteristics include a series of variously sized, embedded linear chains of cells aligned perpendicular to the surface… Expand
