Why is the Brachiosaurus neck so long?

Why is the Brachiosaurus neck so long?

Using a simplified mathematical model and varying parameters such as the weight of the body, the length of the neck and the height of the neck’s attachment to the body, the duo found that a longer neck would have increased the energy efficiency of foraging for plants close to the ground because it would reduce how much …

Is Seismosaurus the longest dinosaur?

At 120-150 feet Seismosaurus was the longest dinosaur. The three supergiant sauropods–Seismosaurus, Brachiosaurus, and Supersaurus–weighed almost 100 tons (200,000 pounds), or the combined weight of fifteen large elephants. Diplodocus was smaller at 15-20 tons.

How did the Apatosaurus kept their long neck upright?

Sauropod dinosaurs — the group including the well-known Apatosaurus (formerly known as Brontosaurus) — could not have kept their long necks in a vertical position, according to a new study. “Like horses, (sauropods) used their muscles to pull the neck down, not up.” …

What is the advantage of sauropods have such long necks?

How long was a Brontosaurus neck?

50 feet
The dinosaurs’ necks reached up to 50 feet (15 meters) in length, six times longer than that of the current world-record holder, the giraffe, and at least five times longer than those of any other animal that has lived on land.

Which animal has longest neck?

giraffes
Among living animals, adult bull giraffes have the longest necks, capable of reaching about 8 feet (2.4 m) long. No other living creature exceeds half this length.

Did giraffes evolve from long neck dinosaurs?

No. Brachiosaurus was a dinosaur that lived around 150 million years ago. By the time that Brachiosaurus became extinct, there were already early mammals called Eutheria living alongside the dinosaurs. The Eutheria gave rise to the placental mammals and then the Artiodactyla and, eventually, the modern giraffe.
