“…Given the general supposition, using oxygen-isotope paleothermometry and faunal/ floral distributions, that the Maastrichtian was globally cooler than the preceding mid and Late Cretaceous stages (for example, Voigt, 1964;Naydin, Teys, and Zadorozhnyy, 1966;Douglas and Savin, 1975;Wolfe and Upchurch, 1987;Kolodny and Raab, 1988;Arthur, Dean, and Schlanger, 1985;Spicer and Parrish, 1990;Clauser, 1994;Ditchfield, Marshall, and Pirrie, 1994;Huber, Hodell, and Hamilton, 1995), it seems likely that equatorial sea-surface temperatures were above 30°C during the Albian-Campanian interval. This view is consistent with paleotemperature determinations from planktonic foraminifera from the Cretaceous of the Pacific (Price and others, 1998) and Atlantic (Norris and Wilson, 1998) as well as with extrapolated southern-hemisphere paleotemperature trends (Clarke and Jenkyns, 1999).…”

ABSTRACT. Many guyots in the north Pacific are built of drowned Cretaceous shallow-water carbonates that rest on edifice basalt. Dating of these limestones, using strontium-and carbon-isotope stratigraphy, illustrates a number of events in the evolution of these carbonate platforms: local deposition of marine black shales during the early Aptian oceanic anoxic event; synchronous development of oolitic deposits during the Aptian; and drowning at different times during the Cretaceous (and Tertiary).Dating the youngest levels of these platform carbonate shows that the shallow-water systems drowned sequentially in the order in which plate-tectonic movement transported them into low latitudes south of the Equator (paleolatitude ϳ0°-10°south). The chemistry of peri-equatorial waters, rich in upwelled nutrients and carbon dioxide, may have been a contributory factor to the suppression of carbonate precipitation on these platforms. However, oceanic anoxic events, thought to reflect high nutrient availability and increased productivity of planktonic organic-walled and siliceous microfossils, did not occasion platform drowning. Neither is there any evidence that relative sealevel changes were the primary cause of platform drowning, which is consistent with the established resilience of shallow-water carbonate systems when influenced by such phenomena.Comparisons with paleotemperature data show that platform drowning took place closer to the Equator during cooler intervals, such as the early Albian and Maastrichtian, and farther south of the Equator during warmer periods such as Albian-Cenomanian boundary time and the mid-Eocene. Initiation of one carbonate platform relatively close to the Equator, at paleolatitudes more northerly than those where others drowned, took place during the cool early mid-Aptian. These correlations are in accord with an interpretation that excess warmth in shallow peri-equatorial waters proved inimical for many carbonate-secreting organisms living on the platforms, allowing subsidence or eustatic sealevel rise to outpace sedimentation and guyots to form. A parallel may be drawn with the recent phenomenon of coral and foraminiferal bleaching, whereby photosynthetic symbionts succumb to prolonged high temperatures (G30°C) and the host organism dies. The fact that most Cretaceous guyots reside in the north Pacific may not be solely related to the age-distribution pattern of ocean floor but to their having run the gauntlet of a difficult and dangerous passage across the Equator. North Pacific guyots are relics from the Cretaceous (and Eocene) ''greenhouse'' Earth.

“…From Belgium and France, material studied comes from six localities. Whether the chalk at Vigny in the Paris Basin is of Campanian, Maastrichtian or even Danian age has long been under discussion (e.g., Voigt 1964). According to Montenat et al (2002), the chalk in the quarries in the vicinity of Vigny is of Danian age surrounded by Campanian chalk.…”

Species commonly assigned to the cheilostome bryozoan genus Onychocella Jullien, 1882 are numerous in deposits of Late Cretaceous age. Among these are 15 species with wide stratigraphical and geographical distributions that are better placed in the genus Rhagasostoma Koschinsky, 1885. These are used here to show similarities between Late Cretaceous bryozoan associations from Western Europe and Central Asia. Type and additional material was examined of several species from the Turonian to the Maastrichtian of Western Europe, including material studied by R.M. Brydone, E. Voigt and T.A. Favorskaya and undescribed material from the Campanian and Maastrichtian of several localities in Eastern Europe and Central Asia. The new species Rhagasostoma brydonei sp. nov., R. aralense sp. nov. and R. operculatum sp. nov. are introduced. New and published data on the morphology and the stratigraphical and geographical distributions of R. inelegans (Lonsdale, 1850), R. gibbosum (Marsson, 1887), R. gibbosulum Brydone, 1936, R. rowei (Brydone, 1906) and R. mimosa (Brydone, 1930) is presented.

“…This is in good agreement with the evidence from fossil plant communities in the same region (Koch, 1959(Koch, , 1963(Koch, , 1964. Faunistic evidence from the more southern localities indicates higher temperatures (Voigt, 1964). We are thus faced with the fact that the Upper Cretaceous 5, in Sharpton, V. L., and Ward, P. D., eds., Global catastrophes in Earth history; An Society of America Special Paper 247. temperatures were, globally speaking, relatively high (compare also Barron and Washington, 1982;Donn, 1982;Arthur and others, 1985).…”

Temperatures in Late Cretaceous times were very high (16 to 20°C) at paleolatitude 62°N. It is suggested that these high temperatures were due to high atmospheric concentrations of CO2 caused by volcanism. Associated with the high CO2 production was a production of elementary carbon.As the volcanism was of the hot-spot type, the dust carried poisonous compounds that reduced the fertility of herbivorous dinosaurs, causing diachronous extinctions. The volcanic activity initiated about 350,000 yr earlier than the marine Cretaceous/Tertiary boundary.At the peak of volcanic activity the CO2 concentration in the atmosphere passed a threshold value of 5,500 ppm, causing the top of the ocean to become acidic. This resulted in the elimination of calcareous plankton.Due to volcanic dust veils the temperature of the topmost part of the ocean fluctuated. The fluctuations led to precipitation of carbonate in the upper acidic part of the water column. The result is a chemical sediment deposited on top of the Cretaceous/Tertiary boundary bed.The Cretaceous/Tertiary extinctions may thus be seen as caused by one long volcanic event with a duration of more than 350,000 yr. It is most likely associated with the extrusion of the Deccan Traps.
