Pieces of a puzzle
More and more “dino-birds” are being discovered,
and each discovery helps our understanding. This
model is based on feathered fossils found in China.
Caudipteryx
was about
the size of a turkey.
Why feathers?
Feathers protect birds
from water and from
temperature changes,
and they may have
evolved on some
dinosaurs for the
same purpose.
We have claws
Some modern birds have clawed wings.
Hoatzin chicks have two tiny claws at
the end of each wing. These are not used
in the adult, but the chicks use them to
clamber through trees.
Feathers provide good
insulation from cold.
Caudipteryx
was a
Cretaceous creature.
Caudipteryx
had clawed
hands. It also had teeth.
Although some dinosaurs
had feathers, experts are still
discussing the possible link
between dinosaurs and birds.
It does seem unlikely,
though, that any
dinosaur flew.
