L\u2019Ornithomimus<\/strong> <\/u>a \u00e9t\u00e9 d\u00e9couvert par le pal\u00e9ontologue am\u00e9ricain Othniel Charles Marsh<\/strong>.
2.Ou \u00e0 t\u2019il trouver le fossile de ce reptile?<\/p>

Les fossiles ont \u00e9t\u00e9 trouv\u00e9s en Am\u00e9rique du Nord<\/strong>, principalement au Canada (Alberta)<\/strong> et aux \u00c9tats-Unis (Colorado, Montana)<\/strong>.
3.Quand il a trouve le premier os de ce reptile?<\/p>

4.Il est carnivore ou herbivore?<\/p>

Le premier fossile a \u00e9t\u00e9 d\u00e9couvert en 1890<\/strong>.

Son poids est estim\u00e9 entre 150 et 200 kg<\/strong>.
7.L\u2019Ornithosaurus vient du cr\u00e9tac\u00e9,du tria ou du jurassique?<\/p>

Il vivait \u00e0 la fin du Cr\u00e9tac\u00e9<\/strong>, il y a environ 76 \u00e0 66 millions d\u2019ann\u00e9es<\/strong>.
8.De quelle famille appartient l\u2019Ornithosaurus?<\/p>

Il appartient \u00e0 la famille des Ornithomimidae<\/strong> (dinosaures ressemblant \u00e0 des autruches).
9.Combien \u00e0 v\u00e9cu l\u2019Ornithosaurus ?<\/p>

probablement entre 10 et 20 ans<\/strong>.
10.Combien fait la taille de ces dents ?<\/p>

Comme le Gallimimus, Ornithomimus n\u2019avait pas de dents<\/strong>. Il poss\u00e9dait un bec corn\u00e9 \u00e9dent\u00e9<\/strong>.
11.Quel est sont nom scientifique ?<\/p>

Son cerveau \u00e9tait assez d\u00e9velopp\u00e9 pour sa taille, probablement autour de 50 \u00e0 100 grammes<\/strong>, ce qui le rendait assez intelligent pour un dinosaure.
13.Il vit seul ou en troupeau?<\/p>

Les pal\u00e9ontologues pensent qu\u2019il vivait en troupeaux<\/strong>, car des fossiles multiples ont \u00e9t\u00e9 retrouv\u00e9s ensemble.
14.Qui est son premier os qui a \u00e9t\u00e9 trouv\u00e9?<\/p>
