These botanists had in their hands, however, plants from two dis- tinct horizons, — the Cretaceous coal measures of Vancouver Island, and Tertiary formations occurring at Bellingham Bay and elsewhere on the southern coast of the mainland of British Columbia ; and as at that time such plants were not known to occur in the Cn»ta- ceous elsewhere, it was natural that they shoiild refer the whole to the Tertiary.

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. Cretaceous Periods 1. • The Cretaceous Period (meaning "chalk," from the many chalk deposits of this age [the White Cliffs of Dover, to name one]) easily stands as one of the most popular times among the general populus.

The period extends from about. Thick Cretaceous sedimentary deposits form a narrow belt of outcrops from British Columbia to Central America. They extend throughout the Rocky Mountains and western Plains states, around the north edge of the Mississippi embayment, and along the southern and eastern sides of the Appalachian Mountains.

Logan, external scan. The Cretaceous-Tertiary extinction The most famous of all mass extinctions marks the end of the Cretaceous Period, about 65 million years ago.

As everyone knows, this was the great extinction in which the dinosaurs died out, except for the birds, of course. Answer to 1/ the most important flora event of the Cretaceous was?.

2/ the environmental effect at the Cretaceous Tertiary (Paleog. 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.

CRETACEOUS SYSTEM, the group of rocks which nor mally occupy a position above the Jurassic System and below the Tertiary. In many areas, the system (from Lat. creta, white chalk, a characteristic rock-type of the Upper Cretaceous in N.W.

Europe), falls naturally into two divisions; the lower is sometimes regarded as a separate system (the Comanchean) in North America, where the .The Cretaceous Period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic Period (i.e. from ± million years ago (Ma)) to the beginning of the Paleocene epoch of the Tertiary Period (about ± Ma).

As the longest geological Period, the Cretaceous constitutes nearly half of the Mesozoic. The end of the Cretaceous defines the boundary.Old tertiary angiosperm (and other) plants have been collected in a travertine mountain near Sézanne in France. Travertine is a sinter which is formed when chalky water comes out of a mountain slope.

The chalk is precipitated on everything lying around, like plant remains and also dead small animals (when present). In most cases the travertine will decay within a short time, but in de.
