Troodontidae

Description
Source: Wikipédia
Les Troodontidae (en français troodontidés) forment une famille éteinte de petits dinosaures théropodes ressemblant à des oiseaux, ayant vécu du Jurassique supérieur jusqu'à la fin du Crétacé. Cette famille érigée en 1924 par Charles Whitney Gilmore est restée mal connue jusqu'à la fin du XXe siècle. C'est alors que de nombreuses découvertes réalisées essentiellement en Chine ont fourni des squelettes souvent complets de plusieurs nouveaux genres avec, pour certains spécimens, une préservation de plumes, d'œufs, d'embryons et d'individus juvéniles.
Les études anatomiques conduites sur les Troodontidae, en particulier les plus primitifs comme Sinovenator, montrent de grandes similarités avec sa famille groupe frère des Dromaeosauridae, mais aussi avec les dinosaures volants du clade des avialiens comme Archaeopteryx. Ceci conduit à regrouper ces trois taxons au sein du clade des Eumaniraptora, lui-même inclus dans le clade des Paraves.
