DISCOVERED IN AUSTRALIA: Scientists
in Australia have discovered the fossil of a giant wombat, which,
at the size of a rhinoceros, would have been the largest marsupial
to ever live. The creatures are believed to have gone extinct just
55,000 years ago, either due to the arrival of humans or climate
change. The nearly complete skeleton includes tusks and indicates a
tiny brain. Included in the fossil was the tooth of a giant lizard,
which scientists believe became dislodged as it feasted on the
giant wombat’s corpse.
