- C2 Sequence (Fairmount)
- Zoarium Morphology: Unbranching, simple “frond”
- Zoecia: Sub-elliptical; arranged diagonally in intersecting series (angles between 50* and 80*)
- Mesozooids: Few
- Monticules: Prominent, raised; form transverse ridges across frond, giving the surface a “wrinkled” appearance
Diagnosis: Wide, robust fronds that irregularly expand in comparison to E. maculata (Bassler)
Escharopora pavonia from the Maysville-Fairmount Formation of Cincinnati, Ohio (CMC 13101)
- Forms broad fronds
- James’s name Stictopora clathratula was published without description and therefore a nomen nudum. As indicated above, Nicholson described the species using James’s specific name, and as his descriptions are based on typical Escharopora pavonia, James’s name is also synonymous with this species.
- D’Orbigny’s species is distinguished from the other forms of Escharopora by its broad zoarium. It is a common fossil and is found at most localities in Ohio, Kentucky, Indiana, and Tennessee where the beds of the Fairview formation are exposed.
- Corallum forming a thin, undulating expansion, often of considerable extent, varying in thickness from one to about two lines, the corallites in two layers with their bases fixed to a medium plane marked by a delicate membrane and opening on opposite sides of the corallum. Surface often with low, rounded monticules, often obscure, and arranged in diagonal rows at intervals of from one to one and a half lines apart, occupied by calices of ordinary size. Corallites generally oblique at their origin, but almost immediately bending outwards, and opening at right angles to the surface or nearly so. Calices elongated, pentagonal, tolerably uniform in size and often arranged in obliquely intersecting lines. No interstitial tubes.
