    Approximately 30% of the animal and plant species that were alive during the cretaceous survived into the Tertiary. This includes some mammals, crocodilians, birds, snakes, insects and even tree. Latest Cretaceous leaf floras from southern Poland and western Ukraine.

    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 .

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.
