Xenarthrans are not part
of life in our country.
Fifty-nine million years
ago, they appeared in
South America, part of
the group of armadillos,
anteaters, and the ever
popular sloth. Unique
joints include extra
spinal cords in their
lower spines. Although
they have low metabolisms
and small brains, they get
along just fine with their
large claws for digging
or climbing. Sadly,
xenarthrans have only
singular vision.
