During a detailed palynological study of the Milk River Formation in southern Alberta, Canada, a diverse and well-preserved assemblage of fungi including dispersed fungal spores and isolated fragments of microthyriaceous fruiting bodies were encountered and these are described. Based on ammonites, magnetostratigraphy, and palynomorphs, these strata are dated as latest Santonian to?earliest. Ruth A. Stockey, Harufumi Nishida, Gar W.

Floras across this region, and in Svalbard and Greenland, suggest a possible thermal maximum for the past m.y. (Heer, ; Schweitzer, ; Wolfe and Poore, ; Francis and McMillan, ). The cretaceous group has generally been divided into an Upper and a Lower series, the Upper called familiarly the chalk, and the Lower the greenmiid; the one deriving its name from the predominance of white eartlry limestone and marl, of which it consists in a great part of France and England, the other or lower series from the plentiful.

At Eidsbotn and Viks Fiord grabens, Upper Cretaceous sediments are preserved in syndepositional down-faulted blocks within the Palaeozoic carbonate that covers much of Devon Island today (Mayr et al.

Several highly effective fire-adaptive traits first evolved among modern plants during the mid-Cretaceous, in response to the widespread wildfires promoted by anomalously high atmospheric oxygen (O 2) and extreme ny, or long-term canopy seed storage, is a fire-adaptive strategy common among plants living in fire-prone areas today, but evidence of this strategy has been.
The gem-grade jet found in Upper Cretaceous rocks of the Jet Basin, Wayne County, Utah, has been shown to be a vitrinitic, high-volatile B bituminous coal with aberrant chemical constitution.

Palynofloral and macroplant evidence from the DPF suggests that the forest canopy was formed primarily by taxodiaceous, cupressaceous, and podocarpaceous conifers [,], a composition typical of most Late Cretaceous warm temperate forests. Abstract: The validity of using quantitative analyses of wood anatomical characters as systematic tools and as palaeoenvironmental proxies has been questioned on the basis that natural variability.

Fossils of trees that appear to be similar to these are the dominant fossil found in the early Cretaceous when they were distributed all over the world including at high latitudes. The Upper Cretaceous is the last geological epoch in the began million years ago, and ended 66 million years ago.
The Cretaceous is traditionally divided into Lower Cretaceous (early), and Upper Cretaceous (late), because of the different rocks reflect the conditions in which they were formed.
From lowest to highest, it is subdivided into the Cenomanian, Turonian. Chris Mays, David J.

The Royal Danish Academy of Sciences and Letters, Copenhagen, Biologiske Skrifter, 57 pp. ISBN The plant-remains of the Lower Cretaceous greatly resemble those of the Jurassic period, consisting mainly of Ferns, Cycads, and Conifers.
The Upper Cretaceous rocks, however, both in Europe and in North America, have yielded an abundant flora which resembles the existing vegetation of the globe in consisting mainly of Angiospermous Exogens and.
Continents were on the move in the Cretaceous, busy remodeling the shape and tone of life on Earth. At the start of the period, dinosaurs ruled the loosening remnants of the supercontinent Pangaea.
It is long-lived (a group of clones in Sweden was carbon-dated at years old) and is relatively slow-growing: this year’s Trafalgar Square Christmas tree is 27 metres tall and was 95 years.Cretaceous Period - Cretaceous Period - Types of Cretaceous rocks: The rocks and sediments of the Cretaceous System show considerable variation in their lithologic character and the thickness of their sequences.

The Winton Formation of central-western Queensland provides a detailed insight into the continental biota of eastern Gondwana during the middle part of the Cretaceous Period, with deposition spanning from the upper Albian to the upper Cenomanian–lower Turonian (approximately –92 million years ago; Tucker et al., ; Tucker et al., ; Tucker et al., ).
