James Lovelock's book "The Revenge of Gaia" suggests that Gaia has many mechanisms for eliminating civilisations that do harm through greenhouse gas emissions and global warming, but suggests that with increasing heat being received from the sun, Gaia's ability to "bounce back" as it did after the Permian and Cretaceous extinction events, may be increasingly compromised.
•
An opposite view is that humankind is Gaia's immune system itself, perhaps evolved to avert future catastrophes such as the Permian and Cretaceous mass extinctions of species.
These two lineages must have separated during the Mesozoic already, as Madagascar and the Indian Plate had separated by the end of the Cretaceous.
He now directed his attention to the fossils of his native country, more especially to those of the Cretaceous and Jurassic strata, and in 1854 he commenced the publication of his great work, Matériaux pour la paléontologie suisse, ou Recueil de monographies sur les fossiles du Jura et des Alpes..., a series of quarto memoirs, of which six were published (1854-1873).

Thanks to the documents the hero was carrying, they determined that the third bomb was planted in the Cretaceous period.
In West Antarctica conifer forests dominated through the entire Cretaceous period (146–65 Ma), though Southern beech began to take over at the end of this period.

The highest concentration of species occurred in the Tethys Ocean during the upper Cretaceous.
Small hesperornithine bones are known from the freshwater deposits of the Late Cretaceous of the Judith River Group as well as the Hell Creek and Lance Formations as well as Eurasian sites.
His earlier work comprised a monograph on the Cretaceous bivalve mollusca of Gosau (1863–66); and an essay on the Tithonian stage (1870), regarded as equivalent to the Purbeck and Wealden formations.
Several teeth referable to Lusitanisuchus were also found from Porto Dinheiro, Lourinhã in strata deposited during the Berriasian stage of the Early Cretaceous, extending the temporal range of this taxon by about 15 Ma.
Upper Cretaceous cyclic sequences in Germany and marl–opal-rich Tortonian-Messinian strata in the Sorbas basin related to multiple sea drawdown have been correlated with Milankovitch orbital forcing.
His more detailed researches related to the Jurassic and Cretaceous Ammonites and to the Tertiary freshwater mollusca; and in these studies he sought to trace the descent of the species.

Known as the Embothriinae, this is an ancient group with roots in the mid Cretaceous, when Australia, Antarctica and South America were linked by land.
Birds, which were already well established by the end of the Cretaceous, also experienced an adaptive radiation as they took over the skies left empty by the now extinct Pterosaurs.
It taps reservoirs in the Cretaceous formations of the Western Canada Sedimentary Basin for oil and gas production.
The group took quite a hit at the Cretaceous–Paleogene boundary (K–T boundary), with only the Pleurotomariidae surviving the Cretaceous–Paleogene extinction event – and then only in deep waters.

There are some other, undescribed, presbyornithid or possible presbyornithid remains, such as the partial right scapula BMNH PAL 4989, which was considered part of Headonornis hantoniensis, but cannot be positively refererred to a known taxon, or the Early Cretaceous remains from the Mongolian Barun Goyot Formation at Uday Sayr

It was 2.50 cm (1 in) long and possibly sucked the blood of pterosaurs in the Cretaceous, in the way that bat fleas feed on bat blood today.

In 2007, Bottke published a paper in Nature (with David Vokrouhlicky and David Nesvorny), proposing that the asteroid that produced the Chicxulub Crater and caused the Cretaceous mass extinction (although the latter is still contended) formed during an asteroid breakup in the main asteroid belt approximately 160 million years ago.
