«Description: Shell thick, moderately inflated; right and left valves similarly sculptured with 6 broadly spaced rows of upturned spines and intervening nodose lirae.
Discussion: The broadly spaced spine rows and the nodose intervening lirae distinguish this species from Spondylus (Spondylus) dumosus with which it occurs. The names refer to the granular texture produced by the nodose lirae. This species is known from the two figured specimens and four additional fragments collected by Harold and Emily Vokes from the Red Bluff Formation at St. Stephens quarry, Alabama.
Type: Holotype 340439 USNM from the Red Bluff Formation, Pelham Hill, St. Stephens quarry, St. Stephens, Washington County, Alabama.
Occurrence: Alabama: Red Bluff Formation, Pelham Hill, St. Stephens quarry, St. Stephens, Washington County, Alabama.»
