Alvarezsauridae

Description
Source: Wikipédia
Alvarezsauridae constitue une famille fossile, assez étrange de petits dinosaures théropodes à longues pattes capables de se déplacer en courant. On pensait au départ qu'ils étaient les premiers oiseaux incapables de voler[réf. nécessaire], mais la plupart des spécialistes les voient aujourd'hui plutôt comme des membres primitifs des Maniraptora[réf. nécessaire]. D'autres travaux suggèrent qu'ils sont un groupe frère des Ornithomimosauria[réf. nécessaire].
Cette famille est très spécialisée. Leurs membres antérieurs sont minuscules mais robustes et complétés par des « mains ». Leur squelette laisse croire qu'ils avaient une imposante poitrine et des muscles des bras peut-être adaptés pour creuser ou déchirer[réf. nécessaire]. Ils possédaient un museau en forme de tube, des mâchoires allongées et des dents minuscules. Ils étaient peut-être adaptées pour se nourrir d'insectes coloniaux, tels les termites[réf. nécessaire].
