Dinosaurs, and extinction.
Dinosaurs are imagined beings based on bones.
Such animals are now extinct.
Its dating is based on carbon 14.
In other words, carbon 14 has a half-life
in which it turns into carbon 12.
And since the concentration of carbon 12 in
relation to 14 is dated.
This dating is only correct if the concentration
of carbon 14 on the earth's surface has never
changed.
But if there was change, then the dating is
wrong.
Assuming that this variation in the Earth's
crust never occurred, then the dating of the
dinosaurs when they existed on Earth was 230
million years ago.
The period of existence that are classified
is the Triassic period until the end of the
Cretaceous period.

The most famous theory for the extinction
of dinosaurs, is the one that says that a
meteor fell to the earth and finished with
the
odifying the earth's temperature and causing
extinction.
This is logical theory, and there are several
gaps.
There are others, with other gaps.
What is certain is that there were animals
that had the bones that were found, and that
they died and left the bones.
