The dinosaur-bird transition has been intensively studied using both fossil and embryological evidence. In recent years, the notion that birds are living dinosaurs has become the mainstream opinion in paleontology. But some embryologists and ornithologists remain skeptical and accuse paleontologists of ignoring conflicting evidence. This book resolves these conflicts. Careful re-evaluation of those features in seeming contradiction reveal that such characteristics actually support and corroborate the mainstream view that birds are in fact members of a dinosaurian lineage - they are living dinosaurs.
