The tallest herbivore dinosaur was Sauroposiden.At 56ft high and 98ft long Sauroposeidon is the tallest and one of the longest dinosaurs in the world, only then to be beaten by Argentinosaurus. Don't believe me go check it out on Wikipeidia.A Dinosaur called Brachiosaurus, Was once the tallest Dinosaur. But now the Highest is one called Sauresposeidon.
The tallest dinosaurs belonged to a the Brachiosaurid group of sauropods. Brachiosaurs, the most well-known among the group was 13 meters tall. Sauroposeidon probably grew up to 18.5 meters tall, making it the tallest dinosaur that ever lived.
The most tallest and strongest plant eating dinosaur was the Argentinosaurus. It was believed to be the largest land animal which had ever lived.
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.
