1929 Goniocladia grahamensis Moore, p.
154-156, pl. 18, figs. 1-3, 8-11.
Material. SNSB-BSPG 2020 XCI 100.
Description. Reticulate colonies consisting of anastomosing bifoliate branches. Branches 0.54– 0.70 mm wide. Fenestrules oval to polygonal, 1.00– 1.36 mm wide and 2.32–2.66 mm long. Autozooecia budding in 2–3 rows from each side of thin mesotheca, opening on both sides of the sharp median carina. Lunaria present, horseshoe-shaped, directed toward fenestrule. Numerous microstylets on the colony surface, 0.008 –0.011 mm in diameter.
Remarks. Goniocladia grahamensis Moore, 1929, differs from G. subpulchra Schulga-Nesterenko, 1955, from the Gzhelian of the Russian Platform, and from G. tenuis Schulga-Nesterenko, 1933, from the Gzhelian of Russia, in having smaller fenestrules (fenestrule width 1.00– 1.36 mm vs. 1.25–2.00 in G. subpulchra and 1.75–2.00 mm in G. tenuis; fenestrule length 2.32–2.66 mm vs. 3.25–4.25 mm in G. subpulchra and 3.15–4.70 mm in G. tenuis).
Occurrence. Upper Graham Formation, Pennsylvanian (Virgilian); Texas, USA. Graham Formation, Pennsylvanian (Virgilian); TXV-200 (“Spillway section at Lost Creek Lake”), Texas, USA.
