Hoxnian Stage
The Hoxnian Stage is a middle Pleistocene stage (Pleistocene from 2.588 ± .005 million to 11,700 years BP[1]) of the geological history of the British Isles. It precedes the Wolstonian Stage and follows the Anglian Stage. It is equivalent to Marine Isotope Stage 11.[2][3][4][5] Marine Isotope Stage 11 started 424,000 years ago and ended 374,000 years ago.[6][7] The Hoxnian divided into sub-stages Ho I to Ho IV.[8]
The Hoxnian stage has often been correlated to the Holstein Interglacial of northern Continental Europe and the Mindel-Riss Interglacial of the Alps. However, there is ambiguity regarding the correlation of these two interglacials to either MIS 11 or MIS 9, which is related to the MIS 12 / MIS 10 ambiguity described in more detail in the article 'Elster glaciation'.[9]
The Hoxnian stage has also been equated to the Yarmouthian (Yarmouth) Stage in North America. However, the Yarmouthian Stage, along with the Kansan, Nebraskan, and Aftonian stages, have been abandoned by North American Quaternary geologists and merged into the Pre-Illinoian Stage.[10][11] At this time, the Hoxnian and Holstein stages are correlated with a brief part of the Pre-Illinoian Stage lying between the Pre-Illinoian A and Pre-Illinoian B glaciations of North America.[5][11]
The Hoxnian Stage is named after Hoxne in the English county of Suffolk where some of the deposits it created were first found. Plant and vertebrate fossils indicate that it was a period of relatively warm climate. Clactonian and Acheulean flint tools and early human remains have been found dating to this stage.
