Geographic Distribution
Australia (Victoria), United States (?Michigan), Pragian, Australia (northern Queensland), Canada (Alberta, Ontario), China (Yunnan), Czech Republic (Moravia), England, France (Boulonnais), Germany (Sauerland), Poland, Russia (Kuznetsk Basin, southern Urals), United States (Ohio), Middle Devonian, Belgium, Canada (Alberta, Arctic islands), China (Guangxi), Germany (Sauerland), Russia (Russian Platform), Frasnian
Age Range
Beginning Stage in Treatise Usage:
Lower Devonian (Pragian)
Beginning International Stage:
Pragian
Fraction Up In Beginning Stage:
0
Beginning Date:
412.4
Ending Stage in Treatise Usage:
Upper Devonian (Frasnian)
Ending International Stage:
Frasnian
Fraction Up In Ending Stage:
100
Ending Date:

Description
Growth form laminar to domical, laminae planar, pillars short, partly superposed, locally crooked or oblique, expanding at tops, wide interlaminar spaces filled with abundant convex dissepiments, astrorhizae irregular. [Flügel (1958) originally published negative prints of Pseudoactinodictyon with low magnification that complicated identification of the genus. Therefore, the species Stromatoporella dualis Khalfina, 1961d, and Stromatoporella undata Yavorsky, 1950, were distinguished as new genera Dualestroma and Intexodictyonella, respectively].
