Paleobiology, 1981
Birds have traditionally been termed the best known group of vertebrates. This cliché, however, relates to the fact that living species are well described, even to the subspecies level. Birds are well known because they are diurnal (therefore easily observed) and because of their aesthetic appeal—birds are beautiful.

Abstract For the Cenozoic era there are a number of well-documented extinction events both in the marine and terrestrial realms, a few of which qualify as mass extinctions. Our knowledge of Cenozoic environments, considerably enhanced within the last few decades by an extensive programme of deep-sea drilling, is greater than that for ...
