Actually, unquestionable angiosperms ("flowering" or "fruiting" plants) are
present in the early part of the Early Cretaceous (as pollen) or the later
part of the Early Cretaceous (as flowers - these were collected not too far
from where I live!). The ancestors of the angiosperms date back to the
Late Triassic, and some fossils of these have been recently collected and
Many paleobotanists suggest that angiosperms developed as quick-growers not
as the result of dinosaur feeding, but in response to the ever-changing
nature of their ancestral habitat: river banks.
