Late Cretaceous vegetation

Paleobotanists divide Phanerozoic time into three eras the Paleophytic, Mesophytic, and Cenophytic Traverse 1988b . The Mesophytic-Cenophytic boundary lies nowhere near the Mesozoic-Cenozoic boundary. Because it is defined by the first appearance of the angiosperms, the Cenophytic begins in the earliest stages of the Cretaceous, some 60-70 million years before the K-T boundary. Angiosperm evolution was rapid in the Cretaceous and global summaries based on megafloral and palynofloral data Crane...
