Dinosaurs Skinnier Than Previously Thought

Dinosaurs were often hefty, but not as plump as previously thought.

A new study describes a new technique used to measure the weight and size of dinosaurs and other prehistoric animals. It could forever change museum exhibits, book illustrations, and other recreations of these now-extinct species. The study appears in the latest issue of Biology Letters

“This is a huge help for any sort of reconstruction,” lead author William Sellers told Discovery News. “We now have a number that suggests how much flesh to add to the bones and that should help people produce animals that are the right balance of too fat or too thin.”

“This technique can also allow you to calculate the numbers you need for more sophisticated locomotor reconstructions, such as the running simulations we have produced in the past,” added Sellers, who is based at the University of Manchester’s Faculty of Life Sciences.

He and his team used lasers to measure the minimum amount of skin required to wrap around the skeletons of large modern animals that included reindeer, 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.
