For the beginning of the Northgrippian a date of 8,236 years before 2000 has been set. The Meghalayan has been set to begin 4,250 years before 2000. 'Tarantian' is an informal, unofficial name proposed for a stage/age to replace the equally informal, unofficial 'Upper Pleistocene' subseries/subepoch. In Europe and North America, the Holocene is subdivided into Preboreal, Boreal, Atlantic, Subboreal, and Subatlantic stages of the Blytt–Sernander time scale. There are many regional subdivisions for the Upper or Late Pleistocene; usually these represent locally recognized cold (glacial) and warm (interglacial) periods. The last glacial period ends with the cold Younger Dryas substage. {{hidden end}}class= "wikitable float-right" width="10%" rules="all" style="float:right; border:1px solid #000000; margin-left:20px; font-size:90%;"
