    The Cretaceous (,), derived from the Latin "creta" (), usually abbreviated K for its German translation Kreide (chalk), is a geologic period and system from to years the geologic timescale, the Cretaceous follows the Jurassic Period and is followed by the Paleogene Period of the Cenozoic is the last period of the Mesozoic Era, and, spanning 79 million years, the . Modern Aracaroiod conifer trees growing in South America. Species of this group of conifers are only found in the southern hemisphere today. 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 life of the Cretaceous displays so great an advance over that of the Jurassic that the change may fairly be called a revolution. Plants. If the separation between the Mesozoic and Cenozoic eras were made entirely with reference to the plants, it would pass between the Lower and the Upper Cretaceous, just as a similar criterion would remove the Upper Permian to the Mesozoic.

The Early Cretaceous (geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from Ma to Ma.

Proposals for the exact age of the Barremian-Aptian boundary ranged from to Ma until recently (as of Paul A. Selden, John R. Nudds, in Evolution of Fossil Ecosystems (Second Edition), During the Cretaceous Period the Earth was The Boreal Lower Cretaceous book than at any other time in its history - atmospheric CO 2 was high and the greenhouse effect led to warm, dry climates.

Polar ice caps melted and the rise in sea level flooded large areas of the continents with shallow seas. The Upper Cretaceous succession (formerly the Colville Group, which was abandoned by Mull et al., ) includes the upper part of the Hue Shale and the Seabee, Tuluvak, lower part of Canning, Schrader Bluff, and Prince Creek Formations (Fig.

Cretaceous polar forests. During the Cretaceous, temperate forests thrived at polar latitudes, as there was a notable difference from current conditions at high latitudes during the Cretaceous polar seasons.

The duration of summer sunlight and winter darkness lasted for approximately 5 months each. This variation in light is thought to have played a critical role in the composition.

Major northwest-trending fluvial systems were encroached and ultimately an interior seaway was extended into Montana. The Danish Cretaceous-Tertiary boundary sequences have three unique claims: a shelf sea setting, rich benthonic faunas, and an insignificant stratigraphic break at the boundary.

Outcrops in the central Danish Basin (northern Jylland) are the most complete while the boundary in the classical Stevns Klint section is marked by a minor disconformity.
