The Tiglian, also referred to as the Tegelen, is a temperate complex stage in the glacial history of Northern Europe. It is preceded by the Praetiglian (stage). The stage was introduced by Zagwijn in 1957 based on geological formations in Tegelen in southern Netherlands. Originally, it was thought to be part of a sequence of glacials and interglacials, namely Praetiglian (cold), Tiglian (warm), Eburonian (cold), Waalian (warm), Menapian (cold), and Bavelian (warm).Kasse (1993), Periglacial environments and climate development during Early Pleistocene Tiglian stage (Beerse Glacial) in northern Belgium, Geologie en Mijnbouw 72, 107-123, Kluwer
