Deep learning of fossil pollen morphology reveals 25,000 y of ecological change in eastern African grasslands
Proceedings of the National Academy of Sciences, Volume 123, Issue 41, October 2026. SignificanceGrasses are a diverse and ecologically important plant clade whose pollen is morphologically indistinguishable under standard optical microscopy. As a result, grass fossil pollen remains an untapped resource in paleoecological and evolutionary ...
