| Description
| - Ontogenetické změny vyjádřené v nejčasnějších růstových stádiích amfiporového skeletu ukazují posloupnosti zcela odlišně od běžných stromatoporoidů. Amfiporové organizmy si prvně budovaly dnové disky či přímo prvotní komůrky (průměry 0.2 mm), a růst těchto struktur bezprostředně pokračoval vzpřímeným růstem jednoduchých rourek. První výskyty povlovně tvořených amfiporových, fibrálně skeletových síťovin se koncentrovaly do zóny proměny, kde se naopak první rourky rozpadaly. Dospělecké rysy amfipor (osní kanál a řídce děrované vnější pozdro či stěna) se pak vyvíjely s mírným zpožděním. Stébla amfipor tloustla nejvíce v prvních mm jejich dělky (do šířky 1.5-2 mm) a další tloustnutí bylo už pomalejší (do 3-5 mm). Celé to svědčí o spojení amfipor s velice starými předchůdci okolo archeocyátů, či jiných mnohobuněčných zdrojů, okolo 0.8 Ga. (cs)
- The ontogenetic changes expressed in the earliest Amphipora-skeleton growth stages suggest that the observed successions can be very different from those of common stromatoporoids. The amphiporid organisms built first their bottom discs or directly the complex first chambers (diameters 0.2 mm), and these structures were directly continued by upright growth of first single tubes. The first occurrences of gradually developing amphiporid skeleton fiber meshworks were concentrated in the zone of metamorphosis, where the first tubes decayed. The attributes of adult amphiporid stages (axial canal and sparsely perforated outer casings or walls) developed with a little delay. The Amphipora stems increased mainly during the first millimeters of their length (to 1.5–2 mm), but further increase of the stems (to 3 or 5 mm) was a very slow process. It can be suggested that amphiporids can be linked to very old ancestors, somewhere around archaeocyaths or common metazoan sources at 0.8 Ga.
