Dinosaur Age Meets the Space Age at NASA Goddard

In 2012, local dinosaur track expert Ray Stanford discovered a nodosaur track from the Cretaceous era on the campus of NASA's Goddard Space Flight Center, in Greenbelt, Maryland. After the slab on which Stanford found the track was excavated, Stanford, paleontologist Martin Lockley, of University of Colorado at Denver, and others documented more than 70 dinosaur and mammal tracks imprinted in the sandstone. Their paper documenting the discovery was published Jan. 31, 2018, in the journal Scientific Reports. The 8-foot by 3-foot slab contains at least 26 mammal tracks. In this video, Stanford and Lockley provide a tour of a cast of the slab, pointing out many of the fascinating tracks. Complete transcript available.
