Impacts of Paleoecology on the TEX ₈₆ Sea Surface Temperature Proxy in the Pliocene‐Pleistocene Mediterranean Sea

The TEX 86 proxy, based on the distribution of isoprenoid glycerol dialkyl glycerol tetraethers (iGDGTs) from planktonic Thaumarchaeota, is widely used to reconstruct sea surface temperature (SST). Recent observations of species‐specific and regionally dependent TEX 86 ‐SST relationships in cultures and the modern ocean raise the question of whether nonthermal factors may have impacted TEX 86 paleorecords. Here we evaluate the effects of...
