恐龙是日本生物学家对英文Dinosauria即“恐怖的蜥蜴”（恐蜴）的翻译，汉语界接受了日文译词，应该知道它不属于汉语的龙类。在1861年发现的始祖鸟化石，与美颌龙化石极度相似，差别在于始祖鸟化石有着羽毛痕迹，这显示恐龙与鸟类可能是近亲。自从1970年代以来，许多研究指出现代鸟类极可能是兽脚亚目恐龙的直系后代。大部分科学家视鸟类为唯一幸存发展至今的恐龙，而少数科学家甚至主张它们应该分类于同一纲之内。鳄鱼则是另一群恐龙的现代近亲，但两者关系较恐龙与鸟类远。恐龙、鸟类、鳄鱼都属于爬行动物的主龙类演化支，该演化支首次出现于二叠纪晚期，并在三叠纪中期成为优势陆栖动物群。
所有的恐龙皆为陆地动物。许多史前爬行动物常被一般大众非正式地认定是恐龙，例如：翼手龙、鱼龙、蛇颈龙、沧龙、盘龙类（异齿龙与基龙）等，但从科学角度来看，这些都不是恐龙。
The
dinosaur
is
the
Japanese
biologist
namely
"terrible
lizard
on
English
Dinosauria"
(fear
of
lizard)
translation,
the
Chinese
community
to
accept
the
Japanese
word,
should
know
that
it
does
not
belong
to
the
Chinese
dragon.
In
1861
discovered
Archaeopteryx
fossils,
extremely
similar
to
compsognathus
fossils,
the
difference
is
archaeopteryx
fossil
traces
of
a
feather,
indicating
that
dinosaurs
and
birds
may
be
the
next
of
kin.
Since
the
1970's,
many
studies
have
pointed
out
that
modern
birds
most
likely
Theropoda
a
direct
descendant
of
the
dinosaurs.
Most
scientists
regard
as
the
only
surviving
species
since
the
dinosaurs,
but
a
few
scientists
even
claimed
that
they
should
be
classified
within
the
same
class.
The
crocodile
is
the
modern
relatives
another
group
of
dinosaurs,
but
the
relationship
between
dinosaurs
and
birds
is
far
more.
The
dinosaurs,
birds,
crocodiles
are
reptiles
of
the
archosaur
clade,
the
evolution
of
a
first
appeared
in
the
Late
Permian
Middle
Triassic,
and
become
the
dominant
terrestrial
animal
group.
All
the
dinosaurs
are
terrestrial
animal.
Many
prehistoric
reptiles
often
is
the
general
public
informally
as
dinosaurs,
pterosaurs,
for
example:
ichthyosaurs,
plesiosaurs,
mosasaurs,
(the
pelycosaurs
dimetrodon
and
edaphosaurus),
but
from
a
scientific
point
of
view,
these
are
not
the
dinosaur.
