Dinosaurs are a | diverse group of reptiles
of the clade Dinosauria.
They first appeared during the Triassic period,
between 243 and 233.23 million years ago,
although the exact origin and timing of the evolution
of dinosaurs is the ( | | | ) subject of active research . | . | .
They became the dominant terrestrial vertebrates
after the Triassic–Jurassic extinction event 201
million years ago; their dominance continued
through the Jurassic and Cretaceous periods.
Reverse genetic engineering and the fossil record
both demonstrate that birds are modern feathered
dinosaurs, having evolved from earlier theropods
during the late Jurassic Period. As such, birds
were the only dinosaur lineage to survive [ ], ( )
the Cretaceous–Paleogene extinction
event 66 million years ago.
Dinosaurs can therefore be divided ( )
into avian dinosaurs, or birds; and non-avian dinosaurs,
which are all dinosaurs other than birds. [ ], [ ];
Children love dinosaurs as is well known;
Pre-mammalian life flourishing
in a global garden of jungles & ice;
why don't children idolize
the Great Heroes who shaped the ( lost ancient
world stone by stone;
what do dinosaurs lead to? it's discovered poets who founded knowledge itself )
( ) they were not so fearsome
as once thought; - clumsy, slow;
birds flying around; where did these creatures come from -
where did the first human
woman emerge - more importantly - ( ) how?
