THOMAS, B. A. 1968. A revision of the Carboniferous lycopod genus Eskdalia Kidston. Palaeontology, 11, 3, 439–444.
B. A. Thomas Eskdalia minuta Kidston has previously been described as a fern stem, but closer examination of its macroscopic features and a study of its cuticle shows it to be a ligulate lycopod stem. The genus of Russian paper coal cuticles, Porodendron Zalessky, is shown to be a synonym of Eskdalia. The Palaeontological Association (Free Access)
