Cientista descobriram uma nova espécie de dinossauro, batizada de Anchiornis huxleyi , a partir de restos fossilizados retirados de depósitos lacustres na província chinesa de Liaoning. Com uma massa estimada em 110 gramas, esta criatura seria a menor espécie de dinossauro (excluindo as aves, já que elas também são "dinossauros". Os ossos do pulso indicam grande mobilidade, prenunciando os mecanismos de asa nas espécies mais avançadas de aves. O Anchiornis possui um mosaico de caracteres que combinam traços de aves e dos dinossauros maniraptores (o grupo mais próximo às aves, que inclui o Velociraptor), e constitui assim mais um perfeito intermediário entre os dois grupos de animais.
