Fossils of the early whale genus " Saghacetus " ( " Sagha whale ", originally named " " Zeuglodon osiris " " ) were first collected at Qasr al Sagha by German explorer Georg August Schweinfurth in January 1886 ( a well-preserved dentary ) . " Saghacetus " is common in the middle of Qasr el Sagha, but there are few other specimens of archaeocetes whales; the only exception being the enigmatic " " Prozeuglodon stromeri " ", named in 1828 based on specimens from 1904, but never adequately described before their destruction during the bombing of Munich in WW2.
