Sauroposeidon is the biggest and comsagmathus, which should be compsognathus, is the smallest
The tallest known dinosaur was a 56 foot tall sauropod. It was called Sauroposeidon.
The tallest known dinosaur was the Sauroposeidon, estimated to have stood around 60 feet tall.
no it is not i think the largest was apatosaurus or brontasaurus
Seismosaurus was the 4th Largest Dinosaur(after Amphicoelis,Sauroposeidon and Argentinosaurus).It was nearly 129.5 feet long(37 metres),stood 20 feet tall and weighed 50 tons
Sauroposeidon is considered one of the tallest dinosaurs, estimated to have been around 60 feet tall. Its long neck and legs contributed to its impressive height.
The heaviest dinosaur that likely has accurate weight estimates is the Argentinosaurus, a sauropod which weighed 73 tons. Argentinosaurus is also the longest known dinosaur, at 98 to 118 feet in length. It is unknown whether Argentinosaurus held its neck upright like Sauroposeidon or horizontally like Diplodocus, so determining which dinosaur was the tallest is difficult. Sauroposeidon, also a sauropod, is known to have held its neck upright, making it 56 feet tall and thus the tallest dinosaur according to current scientific knowledge.
they died
Dino from the Flintstones lived about 40 years!
There are quite a few dinosaurs that could be considered large. The largest is probably Argentinosaurus, at over 120 feet long. Mamenchisaurus was quite big, too. It DID have the longest neck of any dinosaur. 4 other giant dinosaurs are Brachiosaurus, Seismosaurus, Mapusaurus and Paralititan.
Woolungasaurus was a plesiosaur, a long necked marine reptile, not a dinosaur. Its remains are from Australia and date to the late Cretaceous.
It depends how you identify big. The tallest dinosaur was Sauroposeidon, at 18m (60ft). The longest was Supersaurus, which was 35m (112ft) long, and the heaviest was Argentinosaurus, which weighed 80,000-100,000 kg (90-110 tonnes).
