3D printing...'off the beaten track'...as it were....Bird's Paluxy River Dinosaur Chase Sequence
American paleontologist Roland T. Bird, who first excavated the site in 1940, took photographs. Bird also drew maps of the whole site. Falkingham’s team used a technique known as photogrammetry — scanning and combining the photographs — to build a digital model of the site.
Photogrammetry finds the 3-dimensional coordinates of points in the photographs, building a mathematical model of the scene. “We now have the whole trackway in context in a single piece,” said Dr Falkingham. “Here we’re showing that you can do this to lost or damaged specimens or even entire sites if you have photographs taken at the time.
And that means we can reconstruct digitally, and 3D print, objects that no longer exist.”
