Interesting item from Dallas’s Southern Methodist University, where paleontologists Thomas L. Adams, Christopher Strganac, Michael J. Polcyn, and Louis L. Jacobs have used laser scanning to make a high-resolution model of a landmark outdoor dinosaur track in Glen Rose, Texas. Exposed to the elements in the town square, the track is (very slowly) eroding, and the team’s freely downloadable 3D model is intended to both preserve it for posterity and to facilitate its study by fossil buffs all over the world. Their results are published online in Palaeontologica Electronica. [Thanks, Alan Dove!]
