Dinosaurs and palm trees were present north of the Arctic Circle and in Antarctica and southern Australia. Cretaceous period: Evolution of Plant and Animal Life. The climate was also more equable in that the temperature difference between the poles and the Equator was about one-half that of the present. Also, all the rocks that formed during that time have the same proper name of Cretaceous (i.e., they are referred to as the Cretaceous System). Continents were on the move in the Cretaceous, busy remodeling the . Conifers continued replacing seed ferns, ginkgos and cycads. Also, the Rocky Mountains began to rise from the Cretaceous Interior Seaway. Following the Jurassic Period was the Cretaceous Period, which was about 145 million years ago. The Cretaceous Period was the third and final period of the Mesozoic Era. Sea levels continued to rise as continents continued to move, and tectonic plates continued to shift. The Cretaceous is the longest period of the Phanerozoic Eon. At the end of the Cretaceous Period, the dinosaurs . The Differences in Climate, Vegetation, and Landscape During the Cretaceous Period. Data supporting these theories arise from the animal, marine, and vegetation fossils found. Mongolia is a country in Asia, it has borders with China and Russia. The Cretaceous* saw the first appearance and initial diversification of flowering plants (Angiosperms). 1) Numerous evolutionary radiations occurred during the Cretaceous (which harmed life on earth, making it hard to live) 2) A major extinction occurred at the end of the period (as you know the Cretaceous was known for the extinction of dinosaurs) 3) 85% of all species died in the End-Cretaceous extinction. Australia was joined to Antarctica, New Zealand and South America, forming the last remnant of the great southern landmass called Gondwana. The Late Cretaceous Period was a time of great change. The Triassic period was the first period of the Mesozoic era and occurred between 251.9 million and 201.3 million years ago. During the Cretaceous Period the first flowering plants appeared and rapidly diversified. It is the third and final period of the Mesozoic Era, as well as the longest.At around 79 million years, it is the longest geological period of the entire Phanerozoic.The name is derived from the Latin creta, "chalk", which is abundant in the latter half . Cretaceous Period - Cretaceous Period - Paleoclimate: In general, the climate of the Cretaceous Period was much warmer than at present, perhaps the warmest on a worldwide basis than at any other time during the Phanerozoic Eon. It is the last period of the Mesozoic Era, and, spanning 79 million years, the longest period of the Phanerozoic Eon. The Cretaceous The Cretaceous period features a particularly interesting climatic episode in the Earth's geological history. Cretaceous Period climate.

The Cretaceous Period was the last time dinosaurs were alive on earth. Dinosaurs reigned supreme during the Cretaceous period. The Tertiary Period began abruptly when a meteorite slammed into the earth, leading to a mass extinction that wiped out about 75 percent of all species on Earth, ending the reptile-dominant Cretaceous Period and Mesozoic Era. The climate was also more equable in that the temperature difference between the poles and the Equator was about one-half that of the present. Cretaceous stratigraphy in the mid- to low-latitude Asia indicates that the climate was overall dry with large variations in aridity in timescales of 1-100 ka, different from the present-day . Globally, the climate during the Cretaceous Period, like the Jurassic and Triassic, was much warmer than today. The oceans and seas of these regions were populated with marine reptiles, ammonites, and rudists, while dinosaurs ruled the land. The first flowers, ants, and butterflies also appeared during this time. The Cretaceous period was named for the immense chalk formations that blanket much of northwestern Europe, and the main components of this chalk are calcareous nannofossils. Huge reptiles like crocodiles and turtles dominated the swamps at the time, just like their dinosaur predecessors. In general, the climate of the Cretaceous Period was much warmer than at present, perhaps the warmest on a worldwide basis than at any other time during the Phanerozoic Eon. The climate of the Cretaceous Period has been characterized by numerous authors as substantially warmer than the present, gener- ally ice free, and having markedly reduced vertical and latitudinal temperature gradients (Barron, 1983; Crowley and North, 1991; Frakes et al, 1992).
