When most of us think of Ancient Egypt, visions of pyramids and mummies fill our imaginations. For a team of paleontologists interested in fossil mammals, the Fayum district of Egypt summons an even older and equally impressive history that extends much further back in time than the Sphinx.
In a recent issue of the Journal of Vertebrate Paleontology, scientists report on the discovery of six new bat species dating to around 35 million years ago, which sheds new light on the early evolution of bats.
It took over 25 years of fieldwork to collect the 33 specimens that form the basis of the new study. “That translates to a little over one specimen per year – a lot of effort for a single fossil,” said Erik Seiffert, a paleontologist at Stony Brook University. “But it shows just how important patience and long term field programs are to science. Our long-term commitment to field work certainly paid off in this case.” Among the new species is “a giant among bats; though weighing in at less than a half-pound, it is one of the largest fossil bats ever discovered,” said Greg Gunnell, a paleontologist at the University of Michigan.
Fossil bats of Eocene age are rare in Africa. Only a few fragmentary remains from Egypt, Morocco, Tanzania and Tunisia were previously known. The discovery of six new kinds of bats illustrates the remarkably rich, and previously unsuspected, diversity of bats in Africa 37-34 million years ago. – sciencedaily
