From Wikipedia, the free encyclopedia

Gerta Keller (born 1945) is a paleontologist who contests the Chicxulub crater as the location of the meteorite impact, postulated as the cause of the Cretaceous-Tertiary extinction event 65 mya by the Alvarez hypothesis ^[1]. Keller is currently a professor of Geosciences, at Princeton University ^[2].

Keller obtained a doctorate in paleontology and geology from Stanford in 1978 ^[3], and then worked for the US Geological Survey and Stanford University. She came to Princeton University in 1984 and after a few years started studying the K/T boundary ^[4], the geological signature of the Cretaceous-Tertiary extinction event.
