Maniraptora
Maniraptora
(otherwise known as "hand snatchers") is a
clade
of
coelurosaurian
dinosaurs
that includes the
birds
and the non-avian dinosaurs that were more closely related to them than to
Ornithomimus velox
. It contains the major subgroups
Avialae
,
Deinonychosauria
,
Oviraptorosauria
and
Therizinosauria
.
Ornitholestes
and the
Alvarezsauroidea
are also often included. Together with the next closest sister group, the
Ornithomimosauria
, Maniraptora comprises the more inclusive clade
Maniraptoriformes
. Maniraptorans first appear in the fossil record during the
Jurassic Period
(see
Eshanosaurus
), and are
regarded as surviving today
as living birds.
