PALEOECOLOGICAL AND PHYLOGENETIC IMPLICATIONS OF ASEXUAL REPRODUCTION IN THE PERMIAN SCLERACTINIAMORPH NUMIDIAPHYLLUM

From: Journal of Paleontology | Date: January 1, 2004| Author: | Copyright information

ABSTRACT-Numidiaphyllum is one of the Paleozoic scleractiniamorphs. The genus is characterised by a poorly integrated, uniserial fasciculate form with an epithecate wall and simple morphological traits. Parent corallites are divided into several daughter corallites using one mode of division among several theoretically possible alternatives. Bipartite increase is most common, followed by hexapartite and then tripartite increase. Daughter corallites possess relatively large diameters from the beginning, along with a robust colonial pattern. This parricidal increase caused the morphologies of ...
