It's difficult to say at this point. A lot of the largest and possibly tallest dinosaurs aren't very complete.
Brachiosaurus is still the most complete large dinosaur which we can say with reasonable certainly was tall. It might have been able to reach about 14m in height if it's posed with an elevated neck.
There is another brachiosaur called Sauroposeidon which is only known from 4 neck bones. These are very long (the largest bone is 1.4m long). It suggests a dinosaur with a 11 to 12m neck. There are a lot of uncertainties as to what the rest of it looked like so it's default to know exactly how tall it was. Assuming its body was built like that of Brachiosaurus, and it held its neck in an elevated pose, it might have been able to reach about 17m in height.
Sauropoisedon
suropods.
Assuming sauropods have had their necks reconstructed at the correct angles, the tallest dinosaur known was Sauroposeidon. They could be up to 56 feet tall.
Diplodocus
Spinosaurus
The tallest dinosaur ever discovered is a Sauroposeidon.However, this is not the longest or most massive dinosaur.
Sauropoisedonsuropods.
The tallest known dinosaur was a 56 foot tall sauropod. It was called Sauroposeidon.
ultrasaurus
it was titainiosaurus
No. The largest carnivorous dinosaur discovered so far is the Spinosaurus.
The tallest known dinosaur was the Sauroposeidon, estimated to have stood around 60 feet tall.
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.

Heck no, the tallest dinosaur was about as as two houses stacked up.
