"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"

NYT:

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.
