The latest technique is to measure the weight, height and the size of the dinosaurs and other prehistoric animals, which could change the look of exhibition, illustrations and others for research and studies for extinct species.
This will help to have new findings and have a detailed measurement of how much flesh to add to the bones and that should help people to produce these animals in a right and proper way.
“This technique can also allow you to calculate the numbers you need for more sophisticated locomotors reconstructions, such as the running simulations we have produced in the past,” stated Willam Sellers, who is based at the University of Manchester’s Faculty of Life Sciences.
His team yielded laser to measure the requirement of the skin to cover around the skeleton of large modern mammals that included polar bears, giraffes and elephants. Doing this, the researchers noticed that the animals had almost exactly 21 percent more body mass than the minimum skeletal “skin and bone” wrap volume.
Applied to a giant “Brachiosaur” skeleton housed at Berlin’s Museum Für Naturkunde, this formula previously estimated the weight have been as high as 176,370 pounds. This latest study, however, reduces the figure to just 50,706 pounds -- impressively weighty, but not nearly as heavy.” The 23 ton weight (50,706 pounds) is quite low, but I think it reflects the fact that all dinosaur weights are getting lower,” Sellers confirmed, explaining that the estimated weight for this dinosaurs, along with other species, has been dropping since about the early 1960’s.
Recently the high tech scanners and the fast computer will help to measure the accurate details and to calculate the heft of these extinct species. “One very common method is to take an artist’s reconstruction sculpture of the animal and measure its volume by dipping it in water just like Archimedes," Sellers said. "That gives you the volumes, which you can multiply by the density to get its weight.” “The problem with this is the artist’s reconstruction........ are very time consuming to do and probably rather inaccurate, so we thought we’d try a new method.”
He also affirmed that “this is reasonably accurate because the bones fit together like a jigsaw puzzle.” Heinrich Mallison of the Museum Für Naturkunde describes this “a brilliant approach: not trying to estimate soft tissues, but finding out how much a bone-only model underestimates the entire animal's mass.” Mllison believes it is “certainly a very good method for mammals, but I'd like to see tests with more details to find out if crocodiles and dinosaurs have the same regressions, or differ.”
