In India and Pakistan the dinosaurs are found on and close to Cretaceous-Tertiary boundary which show abrupt extinctions.
Taken together, Keller said, the Princeton findings could finally put to rest the theory that the mass-extinction event -- known as the Cretaceous-Tertiary, or KT, for the periods it straddles -- was triggered solely by a large meteorite impact near Chicxulub in present-day Mexico.
2001): Avian evolution, Gondwana biogeography, and the Cretaceous-Tertiary mass extinction event.
The events at the Cretaceous-Tertiary (K-T) boundary have received great attention because of the widespread biotic extinctions that mark the end of the Cretaceous, which represent the last of the five mass extinctions documented in the Phanerozoic record (Raup & Sepkoski, 1982; Jablonski, 1994; Sepkoski, 1996; MacLeod et al.

The Cretaceous unit cropping out in the map area consists of the late Cretaceous Owl Creek Formation with the Cretaceous-Tertiary boundary forming the upper contact.
While studying the aftermath of the Cretaceous-Tertiary, or K-T, extinction, which wiped out the dinosaurs 65 million years ago, Jablonski noticed that many surviving lineages of plants and animals lingered a paltry few million years and then petered out.
I would like to present the hypothesis of a direct link between chemical stress and a major mass extinction process, the Cretaceous-Tertiary (C-T) event, with the aim of providing a more holistic view on the potential of chemical stress on the evolutionary process.
Concrete evidence of noble-gas-trapping fullerenes is seen at the Cretaceous-Tertiary (K-T) boundary as well.
