Which dinosaur is bigger T-Rex or Brochosaurus?

Answer 1

Although these dinosaurs are not comparable in anyway, Brachiosaurus is a much larger dinosaur than a "T-Rex," in every way. Tyrannosaurus Rex stood approx. 20-25 ft tall, while the Brachiosaurus could easily reach heights of 50ft and weighed 50 tons, or 100,000 pounds.

Carnivores like the "T-Rex" tend to be smaller as there metabolism would be higher and there would not be much prey around, so they need to be smaller to survive, they could never feed a larger appetite. So carnivores in all parts of the Animal Kingdom tend to be smaller than omnivores and herbivores.

Brachiosaurus was a herbivore and only ate plant-life, along with the rest of the sauropods, including brontosaurus'. These were the largest dinosaurs, and needed long necks to reach the branches to reach the high up foliage on the massive pre-historic trees.

But move over T-Rex, Brachiosaurus, paleontologists have discovered dinosaurs larger than both of these animals. Sauroposeidon weighing 60 tons and being 16m long takes the cake as the largest dinosaur to walk the earth, which would make it the largest animal to walk this earth. The biggest meat-eater is the Spinosaurus, weighing in at 8 tons.

There is debate what the largest Dinosaur is, names like Bruhathkayosaurus include 7 species of Sauropods that have not been proven they exist, but could potentially be twice as large as the Brachiosaurus.

Answer 2

Tyrannosaurus rex was much larger than Allosaurus. T-rex was about 42 feet (12.8 meters) long and is estimated to have weighed 5-7 tons. The largest well known Allosaurus species was about 32 feet (11 meters) long and weighed only about 2.5 tons.

Google 'allosaurus 45 feet long' you will discover much information that supports the largest fossil remains of allosaurus at this point are much larger than those quoted above.

Troodon was 6.5 Velociraptor was 3 feet tall
