Les sauropodes ont régné sur Terre comme géants ultimes. Voici les 10 dinosaures les plus massifs jamais découverts.
30-40 m, 70-100 tonnes
Probablement le plus gros animal terrestre de tous les temps.
37 m, 70 tonnes
Découvert en 2014, défie Argentinosaurus pour le titre du plus massif.
26 m, 60 tonnes
Squelette le plus complet d'un titanosaure géant — 'sans peur'.
21-26 m, 30-40 tonnes
Dernier titanosaure d'Amérique du Nord, vivait juste avant l'extinction.
27-34 m, 40-50 tonnes
Le plus haut dinosaure connu, 17 m de hauteur (équivalent 5 étages).
21-26 m, 30-50 tonnes
Iconique géant à long cou, célèbre depuis Jurassic Park.
33-34 m, 35-40 tonnes
Le plus long diplodocoïde, queue presque interminable.
26-32 m, 10-16 tonnes
Long et élancé, queue en fouet pouvant briser le mur du son.
20-26 m, 12-16 tonnes
Cou disproportionné — 11 m soit la moitié de la longueur totale.
21-23 m, 16-22 tonnes
Anciennement Brontosaurus, sauropode robuste du Jurassique.
Argentinosaurus huinculensis remains the strongest candidate: estimated at 30 to 40 metres long and 70 to 100 tonnes, this South American titanosaur from the Late Cretaceous is probably the largest land animal in all of history. Patagotitan mayorum (37 m, 70 t) rivals it for this title.
Brachiosaurus altithorax weighed between 30 and 50 tonnes over 21 to 26 metres in length and about 17 metres tall — the equivalent of a 5-storey building. This Late Jurassic sauropod (153-154 Ma) browsed treetops unreachable by other herbivores thanks to its long neck and forelimbs longer than hindlimbs.
Supersaurus vivianae, at 33 to 34 metres, is one of the longest known dinosaurs. Diplodocus carnegii reached 26 to 32 metres with an enormous whip-like tail that could potentially exceed the speed of sound at its tip. In pure length, diplodocoids often surpass the more massive titanosaurs.
Yes — Mamenchisaurus sinocanadorum had a neck of approximately 11 metres, half its total length of 20 to 26 metres. This is the longest neck of any known dinosaur in proportion to its body. This Late Jurassic sauropod from China used this exceptional neck to reach high vegetation without moving its massive body.
