Abstract

The TEX₈₆ paleothermometer is based on the distribution of archaeal membrane lipids (glycerol dialkyl glycerol tetraethers [GDGTs]) in marine sediments. GDGTs are ubiquitous, abundant and relatively resistant to degradation; as such, the TEX₈₆ paleothermometer has been used to reconstruct sea surface temperature during the Cenozoic and early Mesozoic. We review the principles of the TEX₈₆ proxy and developments made over the past two decades. We also discuss its application as a paleotemperature proxy and explore existing challenges and limitations.
