Was a dinosaur print next to it? Sandstone?

am sure these are traces of American nuclear spies

What about the prints found in Glen Rose Texas, that have both human and dinosaur prints together? I'd say those were alot older than a million or so years.

The lateoli foot prints are older than these, dated at at least 3.6 million y.o.
To the 'dino and human footprint' comment. Dinosaurs did not exist with hominids. Off the top of my head, 60 or so mya is when the Dino's became extinct. Primitive monkeys evolve around 50mya. chimps and hominid lines evolve 20-15 mya. So the over lap is not possible with what has been found.

What has NOT been found?
