Larry D. Martin, Origins of avian flight – a new perspective. Oryctos 7, 45-54.
The discovery of a primitive bird-like dromaeosaur (Microraptor) with four functional wings vindicates Beebe’s suggestion that birds went through a tetrapteryx stage in the origin of flight. Flight originated from an arboreal gliding ancestor and Longisquama may be more central to understanding how this came about than previously supposed.
