'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.
