Dinosaurs may not be so heavy

New measurement technique estimates Brinell Giraffatitan weighs 23 tons, much lighter than the previous estimate of 80 tons. A new method for estimating the weight of large animals shows that some dinosaurs may have to much lighter than scientists had thought. Jurassic Park Equipment Animatronic Dinosaur

When the researchers used this technique, they at first with laser scanning the skeleton of a large animal, and then use software to estimate the minimum volume of tissue needed to fill the body cavity of animals, and also calculated the bones and skull in. Next, the team in finding extra 21% on the basis of the volume. The coefficient is a mainly include the limb muscles and flesh the ratio correction factor. Life Size Animatronic DinosaurResearchers explained that the adjustment of 21% from 14 in size ranging from wild boar, caribou to giraffes and elephants existing measurement of large mammals, and the factor is very consistent across different species. Eventually, they will be this animal assumes that the volume multiplied by the average density of the tissue (another factor that comes from modern mammals), resulting in a estimated weight. On June 6, researchers in the United Kingdom was published online in the journal biology letters this outcome. Outdoor Playground Animatronic Dinosaur

When the technology is being applied to the measurement of long-necked herbivores-weight-Brandt's long neck Dragon, the research team found that, while Brandt's long neck Dragon is known to be one of the largest of the species, it is estimated up to 26 meters in length, but it weighed only just over 23 tons. It's really severe, but with some previously reported estimates of this species compared to the weight, to be very far away. Previous estimates, Brandt Giraffatitan weighing up to 80 tons.
