Imagining dinosaurs in the flesh is tricky since the prehistoric subjects died out some 65 million years ago, but a new tool is helping to fill out the skeleton of T. rex and one of the largest-known duckbill dinosaurs, among other beasts.

Paleontologists used laser imaging technology called LiDAR for the first time to create 3-D computer models of five dinosaurs, including two of Tyrannosaurus rex, a spiny predator called Acrocanthosaurus atokensis, the ostrich-like Strutiomimum sedens and the plant-eating Edmontosaurus annectens, a hadrosaur or duckbill dinosaur.
