What did they eat?
One hadrosaur fossil contained
the remains of its last
meal: bark, pine cones,
conifer needles,
and branches.
This tough
plant matter
is particularly
hard to digest.
Did they
have beaks?
That duck-like
beak contained
tightly packed
rows of teeth to
grind vegetation.

A hadrosaur such as
Corythosaurus
would have
roamed in huge herds,
grazing on leaves, pine
needles, and ferns.
A hadrosaur had
more than 1,000
teeth (though not
all were in use at
the same time!).
A number of lizards
and birds have crests.
