Cretaceous Plants from Southwestern Colorado By ROLAND W. BROWN SHORTER CONTRIBUTIONS TO GENERAL GEOLOGY, , PAGES GEOLOGICAL SURVEY PROFESSIONAL PAPER D A study of fossil plants useful in determining the probable boundary between the Lower and Upper Cretaceous depositsCited by: Paleontology and geology. In the early part of the Cretaceous, Colorado lay at sea level and topographic relief was minimal. By million years ago, shallow seas moved into the area, laying down a layer of beach sand and coastal sediments known as the Dakota Formation. The Cretaceous (/ k r ɪ ˈ t eɪ. ʃ ə s /, krih-TAY-shəs) is a geological period that lasted from about to 66 million years ago (mya). It is the third and final period of the Mesozoic Era, as well as the name is derived from the Latin creta, "chalk".It is usually abbreviated K, for its German translation Kreide.. The Cretaceous was a period with a relatively warm climate. The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary (K–T) extinction, was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. With the exception of some ectothermic species such as the leatherback sea turtle and crocodiles, no tetrapods weighing more than 25 kilograms (55 pounds.
