Abstract
The first record of Heterocorallia anywhere in Egypt is in Early Carboniferous (Visean) shallow-marine carbonates of the Um Bogma Formation in west-central Sinai. These strata contain the small, single heterocoral speciesHexaphyllia marginata (Fleming), for which we statistically document marked, intraspecific morphological variations.Hexaphyllia marginata has a global geographical distribution longitudinally but occurs only in the tropical and sub-tropical regions within a latitude range of about 30°N to 30°S. This first EgyptianHexaphyllia occurs with a particular association of exclusively non-dissepimented, small, solitary rugose corals, brachiopods, bryozoans, and other organisms. Small-sizeHexaphyllia marginata might have been so resistant palaeoecologically that they survived even in the unfavourable habitat conditions on an open, subtropical platform.
