Recreating a Dinosaur Chase, 112 Million Years Later

The famous Paluxy River dinosaur tracks in 3-D.

Writing in the journal Plos One, researchers say they took 17 photos of the famous Paluxy River dinosaur tracks and recreated the 148-foot scene in 3-D, showing that a long-necked dinosaur was either chase or followed by a large, two-legged predator. The digitized track reveals enormous stride lengths and deep imprints.
