Britannica online, May 6, 2020: K-T extinction (K-T extinction, mass extinction; abbreviation of Cretaceous-Tertiary extinction, also called K-Pg extinction or Cretaceous-Paleogene extinction; a global extinction event responsible for eliminating approximately 80 percent of all species of animals at or very close to the boundary between the Cretaceous and Paleogene periods, about 66 million years ago; The K-T extinction ranks third in severity of the five major extinction episodes that punctuate the span of geologic time)
Bagley, M. Cretaceous period: animals, plants & extinction event, via Live science website, posted Jan. 8, 2016, viewed on May 6, 2020 (K-Pg extinction event; About 65.5 million years ago, nearly all large vertebrates and many tropical invertebrates became extinct in what was clearly a geological, climatic and biological event with worldwide consequences. Geologists call it the K-Pg extinction event because it marks the boundary between the Cretaceous and Paleogene periods. The event was formally known as the Cretaceous-Tertiary (K-T) event, but the International Commission on Stratigraphy, which sets standards and boundaries for the geologic time scale, now discourages the use of the term Tertiary. The "K" is from the German word for Cretaceous, Kreide)

Cowen, R. The K-T extinction, 1999, via UC Museum of Paleontology website, May 6, 2020 (K-T extinction; this extinction event marks a major boundary in Earth's history, the K-T or Cretaceous-Tertiary boundary, and the end of the Mesozoic Era. The K-T extinctions were worldwide, affecting all the major continents and oceans)
Astrobiology, 2019: p. 303 (One of the "Big Five" mass extinctions in the Phanerozoic Eon occurred at the Cretaceous-Paleogene (K-Pg) boundary (66.0 million years ago). The K-Pg mass extinction was triggered by a meteorite impact that produced a crater at Chicxulub on the Yucatán Peninsula, Mexico)
