When was it that a human left a footprint inside a dinosaur footprint? Sometime in the 50’s?
When was it that a human left a footprint inside a dinosaur footprint? Sometime in the 50's?I don't know. I'll have to look at those old Flintstone episodes.
I think it was in the 1950s. Been awhile since I stopped by Glen Rose, TX, to look at the footprints. I heard they have a life-size wax figure of Tom Landry in the lobby.
Ryanbays forgot one.
