In general, archaeocyathan “Altaicyathus” material (as treated within Porifera/Archaeocyatha) is interpreted from preserved skeletal architecture, typically as a mineralized cup with porous walls and internal longitudinal partitioning, with thalamid-like chambering patterns where initial chambers can be subspherical and pillars may occur across chambers.
Archaeocyaths are treated as a distinct class within the phylum Porifera, representing an early, major diversification of Porifera that is strongly associated with Early Cambrian carbonate shelf and reef environments; archaeocyaths flourished then declined, with a depauperate persistence into the Late Cambrian. Their calcareous (mineralized) skeletons underpin biostratigraphic zonation and regional stratigraphic utility, including notable use in Siberian successions.[2]
Within Archaeocyatha, taxonomy is derived from ontogenetic (developmental) studies of skeletal construction. Higher ranks reflect earlier-appearing structural features, while orders/suborders/superfamilies/families/genera are defined by successive degrees of architectural detail. Diagnostic features used in this higher-level classification include cup types such as one-walled and two-walled cups, the arrangement of (pseudo)septa/(pseudo)taeniae/tabulae, and the presence or absence of supplementary elements such as syringes and dictyonal networks, as determined from ontogeny.[2]
Within this framework, the “Altaicyathina” component (Altaicyathus-related) is characterized by a thalamid-like architecture in which the initial chambers are subspherical, and pillars occur in all chambers.[2]
