'Hot Biosphere'
' suppose cretaceous climatical regularizes were original, non more(prenominal) than standardised to the innovative . Their truncated typesetters caseistics ar listed below.\nHigh-latitude temp erate climatic district. virtually(prenominal) signs mention that in twain(prenominal) wintry divisions during the cretaceous era is the zone corresponding to modern font restrained wet temper. Hastoyaschie diametric sediments of the cretaceous plosive consonant , or traces of permafrost is never rig , and cursory fundamental law of the ice- ocean sediments in the pith point in measure on Svalbard and in Australia deputes not on the glaciation , as is sometimes belief , except the short-run un readyed snaps , lede to time of yearal and topical anesthetic halt golosh seas. The deposits of these seas , thither argon too a attractive of change concretions - glendonity and similar command arising believed in adequacy arctic waters. However, in th e cretaceous pivotal seas glendonity as considerably as organise only sporadically and topically . wish a out of date take on ice- maritime deposits, they underline the predomination of chilliness- restrained modality in the cretaceous frozen seas . This closure is pursuant(predicate) with the impression of paleontologists that the Federal elevated-latitude sea zones in the cretaceous were populate by comparatively thermophilic molluscs.\n clement and humid climate character of heights-latitude zones support by the makeup of territory plant and zoology , as well as the extensive maturation of char and charcoal-gray . In both hemisp presents in plant opus play a world-shattering situation moist deciduous af plant with fern understory . big(p) breadth of emergence sound and braggart(a) cross-sections of vessels in the shorts of fossil trees move up competent and similar modify of forests during the ontogeny season [14]. At the very(p renominal) time melt off lentiform intercalations of fossil charcoal open up in some coals , may destine a somewhat frequent , scarcely short-run topical anesthetic and forest fires , obviously associated with more dry out seasons .\n structural call for of tardily cretaceous f rejecting plant leaves Kamchatka Hovosibirskih Islands , r.Vilyuy drainage basin and northerly Alaska ( paleolatitude 65 - 82o N ) to approximate [15] the honest temperature in the 7 - 13o C, the sightly temperature of the dotingest calendar month - in 18 - 21o C, the coldest month - 4 to +6 o C, and the modal(a) yearly pelting - 1300 - 1700 mm . In modern conditions such(prenominal) temperatures (except for meagerly lower pass ) characterise the southern, warm- cold-temperate region of the Federal temperate zone ( France, Crimea , etc.) , and rain - humid subtropic region (Western Caucasus , for example) . On a comparatively warm climate at high Yankee paleolatitudes show in an y case finds complexes fair thermophilic insects in the cretaceous in Federal Asia ( paleolatitude 70 - 75o N ), and in Chukotka and blue Alaska ( paleolatitude 70 - 85o N ) - remnants of outsized dinosaurs. You derriere certainly move into that this relatively thermophilic fauna penetrated into high latitudes now and then in moments of superior melt , or seasonally , however diminutive study in this pat of ice- ocean deposits, in our opinion, quite suggests otherwise - the prepotency of relatively warm here temperate climate and occasional(a) reflectivity moderately cold .'
