Le Tyrannosaurus rex<\/strong>, souvent surnomm\u00e9 T-Rex<\/strong>,\u00a0 est sans conteste le roi des dinosaures<\/strong> et l\u2019un des plus c\u00e9l\u00e8bres pr\u00e9dateurs de la pr\u00e9histoire. Vivant il y a environ 66 millions d\u2019ann\u00e9es<\/strong>, \u00e0 la fin du Cr\u00e9tac\u00e9<\/strong>, ce gigantesque dinosaure carnivore pouvait mesurer jusqu\u2019\u00e0 13 m\u00e8tres de long<\/strong> et peser plus de 8 tonnes<\/strong>. Avec sa m\u00e2choire puissante<\/strong>, garnie de dents ac\u00e9r\u00e9es atteignant 20 centim\u00e8tres, le Tyrannosaurus rex<\/strong> dominait son environnement et chassait d\u2019autres dinosaures avec une efficacit\u00e9 redoutable. Malgr\u00e9 ses bras tr\u00e8s courts, il poss\u00e9dait des pattes arri\u00e8re muscl\u00e9es<\/strong> qui lui permettaient de courir \u00e0 une vitesse impressionnante pour sa taille.<\/p>

Dot\u00e9 d\u2019un odorat surd\u00e9velopp\u00e9<\/strong> et d\u2019une vue per\u00e7ante<\/strong>, ce pr\u00e9dateur intelligent \u00e9tait parfaitement adapt\u00e9 \u00e0 la chasse. Son nom, qui signifie \u00ab roi des l\u00e9zards tyrans \u00bb<\/strong>, illustre bien sa supr\u00e9matie sur les autres esp\u00e8ces de son \u00e9poque. Aujourd\u2019hui, le Tyrannosaurus rex<\/strong> fascine encore les pal\u00e9ontologues et le grand public, symbolisant \u00e0 lui seul la puissance et la majest\u00e9 du monde perdu des dinosaures.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

1.Qui a d\u00e9couvert le Tyrannosaurus Rex  ?<\/p>\n

Le pal\u00e9ontologue Barnum Brown<\/strong> a d\u00e9couvert les premiers fossiles du Tyrannosaurus rex<\/p>\n
