Branched glycerol dialkyl glycerol tetraethers in Pleistocene loess-paleosol sequences: Three case studies

► Branched GDGTs in three Pleistocene loess-paleosol sequences were analyzed. ► The GDGT-derived proxies disagreed with expected values. ► Various potential analytical and ecological reasons are discussed. ► Caution is advised when interpreting GDGTs in loess-paleosols.
