Wrong calculation, dinosaurs have a few tons of meat left over

According to a recent study, non-giant dinosaurs like Hollywood filmmakers describe due to errors in previous calculations.

The study was published in the London Animal Journal of the Zoological Society, in which Apatosaurus louisae, one of the largest dinosaurs, is actually only half as big as the previous information. Previously, scientists thought that Apatosaurus weighed 38 tons but 18 tons was the actual number.

The Diplodpcus dinosaur actually weighs only 4,000 kg.

Gary Packard, head of research at Colorado State University, said: 'Paleontologists have used the old data for 25 years to calculate the weight of giant dinosaurs and large animals. another extinction. By data through the process of re-examining fossil samples, we found that these figures are seriously flawed and in fact dinosaurs are only half the size of what we still imagine. '

Dinosaurs on Hollywood movies are twice as big as reality.

The samples used by the study included 33 mammal species, from small rodents weighing about 47g to giant species weighing 4 tons.

Scientists have extrapolated the measurements of these animals. However, because the calculation with that logarithm is only a bit wrong, multiply the real size of the dinosaur by many times.

The dinosaurs cannot avoid size errors, such as Styracosaurus, which dropped 21% from 4,200 kg to 3,300 kg; Diplodocus, decreased 27% from 5,500 kg to 4,000 kg.

These new judgments relate to a series of dinosaur biological theories, from energy transformation to meeting the demand for food to the modes of movement.
