Saichania<\/h1>

1.Qui a d\u00e9couvert\u00a0le\u00a0Saichania?<\/p>

Le pal\u00e9ontologue Teresa Marya\u0144ska<\/strong> a d\u00e9crit et nomm\u00e9 Saichania<\/em> en 1977<\/strong> apr\u00e8s l\u2019\u00e9tude des fossiles trouv\u00e9s.<\/p>

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

Les fossiles de Saichania<\/em> ont \u00e9t\u00e9 trouv\u00e9s dans le d\u00e9sert du Gobi<\/strong>, principalement dans la formation de Barun Goyot<\/strong> en Mongolie<\/strong> (et aussi dans certaines zones proches en Chine).<\/p>

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

Les premiers fossiles d\u2019ankylosauriens qui allaient \u00eatre nomm\u00e9s Saichania<\/em> ont \u00e9t\u00e9 d\u00e9couverts lors d\u2019exp\u00e9ditions dans les ann\u00e9es 1970<\/strong>.<\/p>

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

Saichania<\/em> \u00e9tait herbivore<\/strong> (il mangeait des plantes).<\/p>

5.Combien fait sa taille?<\/p>

Il mesurait environ 5 \u00e0 7 m\u00e8tres de long<\/strong> selon les estimations.<\/p>

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

Il devait peser environ 1,4 \u00e0 2 tonnes<\/strong> (2000 kg environ).<\/p>

7.le\u00a0Saichania\u00a0vient du cr\u00e9tac\u00e9,du tria ou du jurassique ?<\/p>

Saichania<\/em> a v\u00e9cu au Cr\u00e9tac\u00e9 sup\u00e9rieur<\/strong> (\u00e0 la toute fin de l\u2019\u00e8re des dinosaures).<\/p>

8.Comment fait la taille du\u00a0Saichania?<\/p>

C\u2019\u00e9tait un dinosaure quadrup\u00e8de<\/strong> (marchant sur 4 pattes), bas, large et tr\u00e8s armur\u00e9<\/strong>, avec une t\u00eate prot\u00e9g\u00e9e de plaques osseuses et une queue possiblement en massue<\/strong> pour la d\u00e9fense.<\/p>

9.De quelle famille appartient\u00a0le\u00a0Saichania\u00a0?<\/p>

Il fait partie des Ankylosauridae<\/strong> (les dinosaures blind\u00e9s)<\/p>

10.Combien \u00e0 v\u00e9cu le Saichania?<\/p>

Saichania<\/em> a v\u00e9cu il y a environ 80 \u00e0 70 millions d\u2019ann\u00e9es<\/strong>, \u00e0 la fin du Cr\u00e9tac\u00e9 sup\u00e9rieur.<\/p>

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

Ses dents \u00e9taient petites et en forme de feuille<\/strong>, adapt\u00e9es \u00e0 manger des plantes \u2013 elles n\u2019\u00e9taient pas tr\u00e8s grandes comme chez les carnivores.<\/p>

12.Quel est sont nom scientifique ?<\/p>

Son nom scientifique complet est Saichania chulsanensis<\/strong>.<\/p>

13.Combien p\u00e8se son cerveau?<\/p>

Comme beaucoup d\u2019ankylosaures, son cerveau \u00e9tait assez petit par rapport \u00e0 son corps<\/strong>, mais on n\u2019a pas de chiffre pr\u00e9cis<\/strong> connu scientifiquement. (pas de donn\u00e9es exactes disponibles)<\/p>

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

On ne sait pas exactement, mais beaucoup d\u2019herbivores dinosaures vivaient probablement en groupes pour se prot\u00e9ger des pr\u00e9dateurs<\/strong> (c\u2019est une hypoth\u00e8se fr\u00e9quente en pal\u00e9ontologie).<\/p>

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

Le fossile complet utilis\u00e9 pour la description (holotype) contenait un cr\u00e2ne et la partie avant du squelette<\/strong>, pas juste un os isol\u00e9.<\/p>

16.Quand il le nomme ?<\/p>

Le dinosaure a \u00e9t\u00e9 officiellement nomm\u00e9 Saichania chulsanensis<\/em> en 1977<\/strong> par Teresa Marya\u0144ska.<\/p>

17.Combien il a de dents?<\/p>

Le fossile du cr\u00e2ne montre qu\u2019il avait des dizaines de petites dents en forme de feuille<\/strong>, mais le nombre exact varie selon l\u2019emplacement dans la bouche.<\/p>

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

\u00c0 la fin du Cr\u00e9tac\u00e9 sup\u00e9rieur en Mongolie (il y a ~80\u201370 millions d\u2019ann\u00e9es), plusieurs autres dinosaures vivaient avec Saichania<\/em> :<\/p>

  • Tarbosaurus<\/strong> \u2013 un grand dinosaure carnivore (proche du Tyrannosaure).<\/p><\/li>

  • Protoceratops<\/strong> \u2013 un dinosaure \u00e0 cornes herbivore.<\/p><\/li>

  • Velociraptor<\/strong> \u2013 un petit dinosaure carnivore rapide.<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
