Description: The trio of scientists and their four alien companions, the mantas, had been ordered to survey this new planet's flora, fauna and mineral resources.  From the very beginning of their mission everything they observed led to one startling conclusion -- this mysterious world was virtually identical with the Earth of the Paleocene period, 70,000,000 years ago at the very dawn of the age of mammals!
