Description
TYPE SPECIES. — Dybowskiella grandis Waagen & Wentzel, 1886 by original designation. Permian; India.
OCCURRENCE. — Middle Devonian – Upper Permian; worldwide.
DIAGNOSIS. — Ramose, hollow ramose, massive, or encrusting colonies. Autozooecia cylindrical, subcircular in transverse section of endozone, having rounded apertures, isolated by abundant polygonal vesicles. Basal diaphragms thin, straight or curved. Lunaria horseshoe-shaped, present in endozone and exozone; ends of lunaria inflect into autozooecial chamber. Autozooecial walls with granular boundary and light-coloured granular-prismatic cortex. Vesicular skeleton in endozone and exozone. Vesicles subrectangular with flat to slightly curved roofs. Small acanthostyles or tubuli in exterior stereom present. Monticules elevated or flat, with central cluster of vesicles surrounded by larger autozooecia in radial arrangement.
COMPARISON
Dybowskiella Waagen & Wentzel, 1886 differs from Fistulipora M’Coy, 1849 in the shape of lunaria, which ends inflect autozooecial chambers. Dybowskiella differs from Eridopora Ulrich, 1882 in having horseshoe-shaped lunaria instead of triangular ones.
