The Ornithopoda (meaning "bird feet")
are an infraorder of herbivorous (plant-eating) dinosaurs.
Early members of this infraorder were small bipedal (walking on two legs)
running animals.
Later Ornithopods were often much larger and at least partially
quadrupedal (walking on
four legs). As a group they were very successful, especially the
duck-bills (Hadrosaurs), it seems principally as a result their
evolution of sophisticated chewing apparatus.
The name Ornithopoda, refers to the animals feet, which in
later species were three-toed (earlier species often had four toes),
and outwardly tended to resemble those of birds (although the
Ornithopoda are not closely related to birds).
Ornithopods first appeared during the
early
Jurassic period,
perhaps around 200 million years ago,
and survived until the
end of the
Cretaceous period.
Ornithopods were among the dinosaurs
which died out during the
mass extinction
of 65 million years ago.
The Ornithopoda infraorder, together with the infraorders of
Ceratopsia ("horned faces")
and
Pachycephalosauria ("thick-headed lizards")
form the the suborder Cerapoda of the
Ornithischian
dinosaurs.
