Dimorphastrea
Taxonomy
Dimorphastrea was named by d'Orbigny (1850) [Sepkoski's age data: J Plie-u T Eo-l Sepkoski's reference number: 682,796]. It is not extant. Its type is Dimorphastrea grandiflora.
It was corrected as Dimorphastraea by Roniewicz (1976), Beauvais (1986) and Turnsek (1997).
It was assigned to Synastraeidae by Beauvais (1986); to Scleractinia by Sepkoski (2002); to Leptophylliidae by Löser (2010); and to Latomeandridae by Roniewicz (1976), Turnsek (1997), Baron-Szabo (2002) and Baron-Szabo (2021).

Diagnosis
Reference | Diagnosis | |
---|---|---|
R.C. Baron-Szabo 2021 | Colonial, massive, hemispherical, thamnasterioid. Budding circumoral. Corallites become arranged increasingly thamno-meandroid with increasing distance from central corallite. Septa subcompact with increasing perforations toward the axial end of the septa. Septal margins granular, septal flanks granular and pennular. Columella papillose, often made of a small number of papillae. Synapticulae abundant. Intertrabecular distance ranging between 150 to around 500 μm. No wall between the corallites. Endothecal dissepiments thin, subhorizontal. |
