Amphiastraeina are connected with their presumed ancestors, Permian Polycoeliidae, by a transitional link - Triassic corals of the family Pachythecalidae Cuif, 1975. During the early Jurassic they differendiated into a few phylogenetic lines and developed certain structural patterns of corallites homeomorphic with those of Rugosa, which had not been, however, recognized in their ancestral group (lonsdaleoid septa/dissepiments, gemmation). Four families are recognized: Amphiastraeidae Ogilvie, Donacosmiliidae Krasnov emend. Roniewicz, Carolastraeidae Eliasova, and Intersmiliidae Melnikova & Roniewicz, fam.n. The earliest Amphiastraeina are described from the ?Hettangian-Sinemurian through the Bajocian and the Callovian of South-East Pamir. One new genus, Prodonacosmilia Melnikova is distinguished.
