"9-foot slab of rock found in a parking lot on the grounds of NASA’s Goddard Spaceflight Center holds the fossilized tracks of several dinosaurs and even a few early mammals"


At one end of the slab, there is a single footprint of a juvenile sauropod, a long-necked plant-eating dinosaur. At the other end is a print from a nodosaur, an armored plant-eater as heavy as a small elephant. Alongside are smaller footprints, a baby nodosaur following its parent.

There are also tracks of four theropods — relatives of the Tyrannosaurus rex that lived tens of millions of years later, but these were smaller, roughly the size of a large raven. Elsewhere on the slab, pterosaurs walked around and even left indentations in the ground where they were pecking for something to eat.


Most intriguing were the mammal tracks.
