Awww! Baby Stegosaurus Tracks Modeled in 3D

Tiny tracks found in Colorado are so small that they could belong to a kitten. Now, those tracks, along with some from adult stegosaurs, have new life as a 3D digital model that could help researchers identify other stegosaurus tracks and learn more about how these spine-backed beasts moved. "We can accurately gauge the depth, the topography of the track and understand how similar and different tracks are to each other," said study researcher Matthew Mossbrucker, director of the Morrison Natural History Museum in Colorado. The model was made with a simple but relatively high-tech method called photogrammetry, in which computer software matches points on two-dimensional photos to build a three-dimensional model of the prints....
