ago, many great animals lived in North America, including
mastodons, saber-toothed cats, and even American horses, but
they all disappeared at the end of the Pleistocene period. The
exact cause of this mass extinction has been a matter of debate
for some time now. Researchers at the University of California,
Santa Barbara however have new evidence that may solve the
mystery.  Studies of prehistoric times often require looking at
the many layers of materials beneath us. Each layer was
deposited at a certain time and the materials of each layer can
tell us about the Earth's situation at the time, and about
certain events. Across what is called the Younger Dryas
boundary, the researchers have found many nanodiamonds. These
small carbon crystals are found in their cubic forms, like those
we use for jewelry, and as hexagonal crystals
