The geographic and stratigraphic distribution are documented. Eighteen genera (one of them new) and at least sixty-four species (eight of them new) are listed: Astropecten? sp. nov., astropectinid sp. nov., Coulonia? sp. nov., Lophidiaster? gr. punctatus/ postornatus, L. pygmaeus Spencer, 1913, Aldebarania sp. nov., Astropectinidae indet., ctenodiscid? indet., benthopectinid sp. 1 (? spp.), benthopectinid sp. 2, Metopaster alexiae sp. nov., M. aff. carinatus Brünnich Nielsen, 1943, M. continuus sp. nov., M. decipiens Spencer, 1913, M. kagstrupensis Brünnich Nielsen, 1943, M. lisannae sp. nov., M. miriamae sp. nov., M. aff. planus (Brünnich Nielsen, 1943), M. praetumidus Schulz & Weitschat, 1975, M. spencerii Brünnich Nielsen, 1943, M. gr. tumidus Spencer, 1913, M. uncatus (Forbes, 1848), M. undulatus Spencer, 1913, M. sp. 1, M. sp. 2, M. sp. 3, M. sp. 4 (aff. elegans Gale, 1987a), Parametopaster? sp., Haccourtaster aemstelensis gen. et sp. nov., Recurvaster antemammillatus sp. nov., R. mammillatus (Gabb, 1876), R. gr. radiatus (Spencer, 1913), R. spiniger sp. nov., Nymphaster alseni (Schulz & Weitschat, 1971), N. spenceri (Rasmussen, 1950), N. studlandensis (Schulz & Weitschat, 1975), N. sp., Chomataster acules Spencer, 1913, Ophryaster? maastrichtensis Umbgrove, 1925, O. magnus Spencer, 1913, O. oligoplax (Sladen, 1891), Comptoniaster peetersorum sp. nov., Crateraster anchylus (Brünnich Nielsen, 1943), C. favosus (Spencer, 1913), C. reticulatus (Schulz & Weitschat, 1981), Caletaster? sp., goniasterid sp. 1, goniasterid sp. 2, goniasterid sp. 3, goniasterid? sp. 4, goniasterid sp. 5, goniasterid sp. 6, goniasterid sp. 7, goniasterid sp. 8, Valettaster gr. ocellatus (Forbes, 1848), Stauranderaster? miliaris Brünnich Nielsen, 1943, S.? sp. (? spp.), Aspidaster? aff. senonensis (Valette, 1902), A.? sp. 1, A.? sp. 2 (aff. pistilliferus Forbes, 1848), Pycinaster aff. cornutus Rasmussen, 1945, P. magnificus Spencer, 1913, P.? aff. rosenkrantzi (Brünnich Nielsen, 1943), P. sp. 1, P. sp. 2, and asteriid sp.
