Stylophyllopsis victoriae, from the Natural History Museum.

Belongs within: Hexacorallia.

The Stylophyllidae are a group of corals known from the Triassic and Jurassic, characterised by septa initially composed of spines or lobes that become covered by sclerenchyma (Stolarski & Russo 2002).

Characters (from Stolarski & Russo 2002): Whole skeleton built of stereomal tissue, organized in bundles of fibres forming wall, radial elements and dissepiments. Bundles of fibres subcylindric or scale−like in shape. Septa composed of spines (or lobes) that are covered with sclerenchymal deposits later in ontogeny.
