Geologists discover `dinosaur dance floor'

SALT LAKE CITY – Geologists say they have discovered prehistoric animal tracks so densely packed on a 3/4-acre site that they're calling it a "dinosaur dance floor."

The site along the Arizona-Utah state line offers a rich new set of clues about the lives of dinosaurs 190 million years ago.

Back then, large stretches of the West were a Sahara-like desert. More than 1,000 tracks were found in what would have been a watery oasis nestled among towering, wind-whipped sand dunes.
