One of 800 images from a CAT scan of the ‘Alvis Delk Cretaceous Footprint’ limestone done at Glen Rose Medical Center. This particular slide was used to measure high density levels in the rock’s material specifically between the last three toes of the human print, showing compression of the material caused by pressure. Below the human print is visible high density levels between the toes of the dinosaur track, as well is other areas adjacent to both prints. Local radiologist Dr. Charles Myers said in his opinion those high density levels could only have occurred by stepping into the rock and compressing it when it was soft. The question now is – when was the rock soft?
