The NASA Goddard Track Slab

Discovered by amateur fossil hunter Ray Stanford in 2012 at NASA Goddard Space Center near Wash. DC

This remarkable find represents the most diverse and dense collection of fossil tracks on one relatively small slab (approx. 8 x 3 ft). It includes over 70 Lower Cretaceous tracks of at least three types of dinosaurs, as well as pterosaurs (flying reptiles), mammals (including the largest Mesozoic mammal track), and invertebrates, plus a coprolite, claw marks, nodosaur scute, and more. Paleontologist Martin Lockley, one of the world's experts on fossil tracks stated: "This is the Cretaceous equivalent of the Rosetta Stone."
