Microraptor

Description

Microraptor (« petit voleur ») est un genre éteint de petits dinosaures saurischiens de la famille des Dromaeosauridae du biote de Jehol (formation de Jiufotang) de Chine, datant du Crétacé inférieur (Aptien inférieur), il y a 120 millions d'années. Comme Archaeopteryx, il démontre le très proche lien de parenté entre Dromaeosauridaes et oiseaux. Comme ces derniers, Microraptor possède des pennes sur les pattes et la queue.
