Rather, it was far larger and more impressive specimens we had come to see and the appearance of dramatic sandstone cliffs on the horizon heralded some of the most extraordinary fossiliferous rocks that I, for one, have ever seen.

The earliest collections were made during a series of expeditions by Georg Schweinfurth, from 1879 to 1886, and it was during these that the first fossil whales were recovered from the Eocene rocks north of Lake Birket Qarun.
