The longest sauropod discovered so far is a sauropod called amphicoelias fragillimus. Scientist estimates that A. fragillimus was nearly 60 meters long, although scientists have only found one incomplete backbone and some of the fossils were lost after being studied.
The longest dinosaur was Amphicoelias fragilimmus.
Amphicoelias measured 40 - 60 m in length, twice a long as a blue whale and its weight was 140 tons.
The largest dinosaur was Bruhathkayosaurus, which measured 30 m and weighed 160 tons.
the longest dinosaur is:
Type: Seismosaurus
Length: 150 feet, give or take a few
Weight: 80 - 100 tons
the biggest dinosaur was Argentinosaurus
Yes, the Apatosaurus is a sauropod dinosaur. Sauropods were herbivorous, lizard hipped, quadrupedal dinosaurs with long necks. Sauropods were the largest dinosaurs ever to exist, and the largest sauropods are the largest animals to have ever lived on land.
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.
hmm.Ultrasaurus was the largest also heviest
the largest of the dinosaurs were the sauropods,or as some people call them,long necked dinosaurs.Argentinosaurus,a huge sauropod,was believed to weigh as much as 110 tons and approximately 120 feet long!Seismasaurus, another huge sauropod, was believed to be almost 130 feet long, making it one of the longest creatures ever to have been known!
none and no buts but maybe because there might be more undiscovered large dinosaurs
Tallest is the giraffe, biggest land animal is the elephant, and largest ever is the blue whale. Unless you count dinosaurs. Then you have to look it up.
The largest prehistoric mammal ever was the Indricotherium a prehistoric rhino like mammal the height of a modern giraffe and weighing 12 tons.
