Dinosaurs are much lighter than previously assumed

Using laser technology to calculate body mass, experts at the University of Manchester, UK, have discovered that giant dinosaurs, with their feet shaking the ground, are actually much lighter. compared to previous assumptions.

Creating a formula to accurately calculate the dimensions of animals, experts noticed a Brachiosaurus, estimated to weigh up to 80 tons, practically weighing only 23 tons.

The study's lead author, Dr. Bill Sellers, asserts: 'Our method provides a much more precise measure and shows that dinosaurs are not as big as they thought although they are still giants.' .

The study, published in the journal Biology Letters, uses lasers to determine the minimum amount of skin needed to encircle the main parts of the skeleton of living animals, including reindeer, polar bear, deer. turtleneck and elephant.

From there, they found that animals have nearly 21% more body mass than the minimum 'skin and bone' volume .

When applied to a Brachiosaur skeleton in the Museum für Naturkunde Museum in Berlin, the results showed that the Brachiosaur weight was 23 tons when alive.

According to Dr. Sellers, this technique can be applied to skeletons of other extinct animals.
