Origin of birds bone by bone

Starting with the first dinosaurs, see how birds evolved, bone-by-bone, ending with basal-most extant birds. Here many of the Late Jurassic Solnhofen birds, traditionally labeled 'Archaeopteryx', are actually a diverse lot, basal to several extinct bird clades, as well as basal to the extant bird clade. You'll see when feathers appeared, teeth disappeared and flapping had its genesis. This list of taxa was derived after phylogenetic analysis.
