This is NOT Late Pleistocene!!!! The Late Pleistocene officially starts with the start of the Eemian. The stratotype of the base of the Late Pleistocene is in borehole (!) Amsterdam Terminal (Netherlands, in which is the type area of the Eemian). The Middle Pleistocene is defined by the Brunhes-Matuyama boundary at its base. Both boundaries are agreed at the last INQUA congress (2007). The other information, e.g. the correlation with the Alpine stage Günz-Mindel is also dubious. This is almost certainly incorrect.-- Tom Meijer ( talk) 10:56, 21 February 2008 (UTC)
The "Yarmouth", which the figure refers to is the former North American "Yarmouth Stage". However, back in the 1980's, Quaternary geologists, i.e. Hallberg et al. (1986), Richmond and Fullerton (1986), Roy et al. (2004), and many others, in the United States abandoned the Aftonian, Nebraskian, Kansan, and Yarmouth stages and merged them all into the Pre-Illinoian Stage (Roy et al. 2004). Thus, the Yarmouth and older North American stages shown in the figure are no longer used in the United States. they should be taken out of the figure as discussed in two of the external links to this article.

According to the Subcommission on Quaternary Stratigraphy, the official name for this stage is either Cromerian Stage or Cromerian Complex. Look at their official stratigraphic charts. Paul H. ( talk) 13:37, 1 May 2015 (UTC)
