  • Stratigraphic distributions largely from Smith Woodward (1902, 1903, 1907a, 1908, 1909, 1911, 1912a). ‘Relevant’ specimens are non-types identified at generic or higher level. Occurrences marked by ‘X’ are definitive, while those indicated by ‘x’ are less certain. Taxa marked with ‘*’ are known from relatively intact skulls. ‘‡’ preceding holotype specimen information indicates that type not from the Chalk Group. Dates of publication in Agassiz (1833–44) follow Brown (in Woodward & Sherborn 1890). Traditional zones are indicated by characters as follows: a, Schloenbachia varians; b, Holoaster subglobosus; c, Actinocamax plenus; d, Rhynchonella cuvieri; e, Terebratulina gracilis; f, Holaster planus; g, Micraster cortestudinarium; h, Micraster coranguinum; i, Uintacrinus socialis; j, Marsupites testudinarius; k, Offaster pilula; l, Gonioteuthis quadrata. Correspondences between these zones and stage-level divisions of the international timescale shown here are inexact (see Fig. 3).
