- The
- end
- of
- the
- mesozoic
- era
- brought
- an
- astounding
- variety
- of
- dinosaurs
- to
- the
- world.For
- most
- of
- the
- Mesozoic
- Era
- (2.52
- to
- 66
- million
- years
- ago),
- reptiles
- known
- as
- dinosaurs
- were
- the
- dominant
- land
- animals
- on
- Earth.
- They
- thrived
- for
- nearly
- 180
- million
- years.
- The
- remains,
- or
- footprints,
- of
- dinosaurs
- were
- first
- discovered
- in
- the
- early
- 19th
- century.
- Since
- then,
- dinosaur
- fossils
- have
- been
- found
- on
- every
- continent,
- including
- Antarctica.
- At
- least
- 1,000
- species
- of
- dinosaurs
- have
- been
- identified.
- Dinosaurs
- were
- diverse
- animals
- with
- vastly
- different
- lifestyles
- and
- adaptations.
- These
- include
- carnivores
- and
- herbivores,
- animals
- that
- walk
- on
- two
- and
- four
- legs,
- and
- animals
- that
- live
- alone
- and
- in
- groups.
- Fossil
- evidence
- shows
- that
- dinosaurs
- ranged
- in
- size
- from
- smaller
- than
- a
- chicken
- to
- more
- than
- ten
- times
- larger
- than
- the
- largest
- elephant.
- By
- examining
- dinosaur
- remains,
- scientists
- have
- concluded
- that
- dinosaurs
- were
- ancient
- relatives
- of
- modern
- crocodiles,
- snakes,
- lizards
- and
- birds.
- Although
- most
- dinosaurs
- became
- extinct
- about
- 66
- million
- years
- ago,
- one
- lineage
- of
- dinosaurs
- evolved
- into
- birds
- about
- 150
- million
- years ago.
