Abstract
Bulk sampling of phosphate-rich horizons within the Late Cretaceous of the Anglo-Paris Basin yielded numerous teeth of members of the Squatiniformes. Along with isolated tooth remains, two museum specimens comprising partial articulated encoskeletal remains including the holotype of the species Squatina cranei Woodward, 1888a are described, and a new subgenus Cretascyllium is proposed for species of the genus Squatina with high degree of heterodonty and triangular anterior teeth. The species Squatina (Cretascyllium) cranei comb. nov. and Squatina (Cretascyllium) hassei comb. nov. are referred to this subgenus. The genus Parasquatina Herman, 1982 previously erected on a single tooth is valid, and two new species P. justinensis sp. nov. and P. jarvisi sp. nov. are described along with a third taxon Parasquatina sp. An enigmatic tooth referred to ?Neoselachii incertae sedis is also reported. The palaeoecology of these taxa is discussed.
