DOMERIAN OF THE YORKSHIRE COAST

Abstract
Summary: The Domerian at the sections near Whitby of Hawsker Bottoms, Kettleness, and Staithes is described in detail. Ammonites listed from each bed have been collected in situ by the writer, and the sequences of species obtained are used as the basis of a critical revision and redefinition of the subzoning of the Domerian. Large-scale maps of the exposures on the foreshore at Staithes are given, and a correlation chart indicates the lateral variation in lithology and ammonite sequences between the three sections. Comparisons with other British and Continental Domerian sections are outlined. In the palaeontological section description of the Amaltheid ammonites is limited to an account of the sequence of species, with short descriptions of some of the more problematical ones; the highest Liparoceratids are summarily described. Rare Domerian representatives of the Hildoceratid ammonites are described in greater detail, as two of the genera are new to the British Isles. A table is given showing the vertical range of all the ammonites found.
