1.Qui a d\u00e9couvert le Ceratosaurus?<\/p>

C’est Othniel Charles Marsh<\/strong>, un c\u00e9l\u00e8bre pal\u00e9ontologue am\u00e9ricain, qui a d\u00e9couvert et d\u00e9crit le Ceratosaurus.<\/p>

2.Ou \u00e0 t\u2019il trouver le fossile de ce reptile?<\/p>

Le premier fossile a \u00e9t\u00e9 d\u00e9couvert dans le Colorado<\/strong>, aux \u00c9tats-Unis, dans les Morrison Formation<\/strong>, une c\u00e9l\u00e8bre zone riche en fossiles de dinosaures.<\/p>

3.Quand il a trouve le premier os de ce reptile?<\/p>

Les premiers fossiles de Ceratosaurus ont \u00e9t\u00e9 d\u00e9couverts en 1884<\/strong>.<\/p>

6.Combien p\u00e8se son poids ?<\/p>

Son poids est estim\u00e9 entre 500 et 1 000 kg<\/strong>, selon les sp\u00e9cimens.<\/p>

7.L\u2019Alamosaurus vient du cr\u00e9tac\u00e9,du tria ou du jurassique ?<\/p>

Il a v\u00e9cu au Jurassique sup\u00e9rieur<\/strong>, il y a environ 153 \u00e0 148 millions d’ann\u00e9es<\/strong>.<\/p>

8.De quelle famille appartient le Ceratosaurus?<\/p>

Il a v\u00e9cu au Jurassique sup\u00e9rieur<\/strong>, il y a environ 153 \u00e0 148 millions d’ann\u00e9es<\/strong>.<\/p>

9.Combien \u00e0 v\u00e9cu le Ceratosaurus ?<\/p>

Comme dit plus haut, il faisait 6 \u00e0 7 m\u00e8tres de long<\/strong>, environ 2 m\u00e8tres de haut au niveau des hanches<\/strong>.<\/p>

10.Combien fait la taille de ces dents ?<\/p>

Ses dents mesuraient environ 5 \u00e0 10 cm de long<\/strong>, elles \u00e9taient pointues et courb\u00e9es vers l\u2019arri\u00e8re, id\u00e9ales pour trancher la chair.<\/p>

11.Quel est son nom scientifique ?<\/p>

Ses dents mesuraient environ 5 \u00e0 10 cm de long<\/strong>, elles \u00e9taient pointues et courb\u00e9es vers l\u2019arri\u00e8re, id\u00e9ales pour trancher la chair.<\/p>

Son cerveau pesait probablement autour de 100 \u00e0 150 grammes<\/strong>, ce qui est petit par rapport \u00e0 la taille de son corps.<\/p>

13.Il vit seul ou en troupeau?<\/p>

On pense qu\u2019il vivait principalement seul<\/strong>, comme beaucoup de grands carnivores.<\/p>

14.Qui est son premier os qui a \u00e9t\u00e9 trouv\u00e9?<\/p>

Le premier fossile important trouv\u00e9 \u00e9tait un squelette presque complet<\/strong>, incluant le cr\u00e2ne, la m\u00e2choire, les vert\u00e8bres et les membres.<\/p>

17.Quels sont les autres dinosaures qui vivaient \u00e0 cette \u00e9poque?<\/p>

  • Stegosaurus<\/strong><\/p><\/li>

  • Diplodocus<\/strong><\/p><\/li>

  • Camarasaurus<\/strong><\/p><\/li><\/ul>
