Birds of the Cretaceous The evolution of birds is not well known, since they preserve badly as fossils Hesperornis or ‘western bird’ was a >1 m long flightless bird of the Late Cretaceous period. Fossil skeletons have been found in Kansas and Alberta, Canada. This fish-eating bird had large, possibly webbed feet and may have been a good swimmer and diver.
