Through associates in Egypt, Gingerich made arrangements to travel to Khasm el Raqaba, the area he had located on Google Earth. "Sure enough, when we got there, there was a huge quarry operation with trucks everywhere, blasting out blocks of limestone," said Gingerich, who is the Ermine Cowles Case Collegiate Professor of Paleontology and director of the U-M Museum of Paleontology. Within minutes of seeing the site, though, Gingerich realized any whale fossils that might be there would be impossible to locate.
Scanning the scene, however, something else caught his eye: bands of red in the white limestone walls of the quarry. He quickly realized the red bands represented layers of loose soil that were blown into ancient caves.
"Suddenly it dawned on me: There should be animals preserved in that sediment, too, because caves often act as traps," Gingerich said. When he searched at the base of one rock outcrop, there were tiny bones everywhere.
Gingerich collected some of the fossils and took them back to the U-M Museum of Paleontology where Gunnell, an associate research scientist, began studying them and identified teeth and bones of fossil bats. Gunnell shared the materials with Ellen Miller of Wake Forest University, who found a few rodent jaws and some additional teeth. Recently, with funding from National Geographic Society, Gunnell, Miller, U-M assistant research scientist William Sanders and Ahmed El-Barkooky of Cairo University visited the site to collect more of the fossils, which may have an interesting story of their own.
The bones and teeth---remains of small mammals that lived in the early Miocene Epoch, some 18 to 20 million years ago---are the first small mammal fossils of that age to be found in
