Scientists have discovered the fossils of two Triceratops
relatives that must have been among the most striking creatures
of their era. The bigger of the two, called Utahceratops gettyi
(top and bottom right), features a large horn above its nose and
two shorter, rounder horns protruding to the side from above
each eye socket. And the beast's 2.3-meter-long skull seems too
huge even for its massive, nearly 4-meter-long body. The
smaller, Kosmoceratops richardsoni, also sports eye horns,
including one each from above and to the side of each eye
socket, plus a large nose horn, and 10 more sprouting from the
rear of its skull's bony frill. The array makes Kosmoceratops
the horniest dinosaur ever found, so to speak, and not without
some justification. Scientists report online today in PLoS One
that Kosmaceratops' accoutrements probably served as an
attraction to potential mates. The team found both specimens,
estimated at between 65 million and 80 million years old, in
southern Utah, on part of a continental land
