The origin and evolution of birds
This text is a comprehensive and illustrated discussion of the origin of birds and of avian flight. Ornithologist and evolutionary biologist Alan Feduccia, author of "Age of Birds," here draws onExpand

Explosive Evolution in Tertiary Birds and Mammals
The traditional view of avian evolution over the past century is that of sluggish gradualism, in which many living orders of birds are thought to have originated from the mid-Cretaceous or so (1),Expand

‘Big bang’ for tertiary birds?
Abstract The early evolution of living birds has been sharply debated, with two disparate interpretations. Molecular-clock studies consistently date the emergence of modern bird orders at ∼100Expand

Evidence from Claw Geometry Indicating Arboreal Habits of Archaeopteryx
The Late Jurassic Archaeopteryx has been thought to have been a feathered predator adapted to running that represented a terrestrial stage in the evolution of true birds from coelurosaurianExpand

Developmental Patterns and the Identification of Homologies in the Avian Hand
Homologies of digits in the avian hand have been debated for 150 years. Cladistic analysis nests birds with theropod dinosaurs. Theropod hands retain only digits I-II-III, so digits of the modernExpand

Early Adaptive Radiation of Birds: Evidence from Fossils from Northeastern China
Late Jurassic and Early Cretaceous birds from northeastern China, including many complete skeletons of Confuciusornis, provide evidence for a fundamental dichotomy in the class Aves that may antedateExpand

A new Chinese specimen indicates that ‘protofeathers’ in the Early Cretaceous theropod dinosaur Sinosauropteryx are degraded collagen fibres
Alleged primitive feathers or protofeathers in the theropod dinosaur Sinosauropteryx have potentially profound implications concerning feather morphogenesis, evolution of flight, dinosaur physiologyExpand
