Synonyms
Aculatostroma
Geographic Distribution
Australia (northern Queensland, Victoria), central Asia (Tien Shan), Russia (Kuznetsk Basin, northeastern Siberia), Lower Devonian; Afghanistan, Austria, Belgium, China (Quizhou), France (Boulonnais), Poland, Russia (Kuznetsk Basin, northeastern Siberia, Urals), United States (Indiana), Middle Devonian; Canada (Alberta), Czech Republic (Moravia), Poland, Russia (Kuznetsk Basin, northeastern Siberia, Russian Platform), United States (Iowa), Upper Devonian; Belgium, Germany, Kazakhstan, upper Famennian.
Age Range
Beginning Stage in Treatise Usage:
Lower Devonian
Beginning International Stage:
Lochkovian
Fraction Up In Beginning Stage:
0
Beginning Date:
419
Ending Stage in Treatise Usage:
Upper Devonian (upper Famennian)
Ending International Stage:
Famennian
Fraction Up In Ending Stage:
100
Ending Date:
359.3
Description
Growth form laminar or domical; laminae continuous, planar, thin; pillars bladelike, laterally joined in chains, short to superposed; galleries labyrinthine in tangential section, rectangular in longitudinal section; astrorhizae rare. [The original figures of Syringostroma verrucosum (Khalfina, 1961d, pl. D13,3a–b), designated as the type species of the genus Aculatostroma Khalfina, 1968b, clearly demonstrate that it has continuous laminae and so-called hexactinellid structure in the interlaminar space. Therefore, Aculatostroma is treated as a junior synonym of Atelodictyon.]
