KEMUSNAHAN MASSAL YANG TIDAK TERBAYANGKAN
”THE GREAT DYING”

In the years since researchers have sought evidence
linking impacts with other mass extinctions of life
throughout geologic history.
The biggest of these, 251 million years ago, ended the vibrant Permian period
and nearly left Earth sterile:
90 to 95 percent of all species died within a geologic blink of an eye.
No compelling explanation for the Permian-Triassic extinction
— widely called the "Great Dying" —
has yet gained favor.

“Those born under the sign of the Dragon are full of intelligence,
vitality and enthusiasm.
The Dragon is a revered sign that appears confident but can be gentle inside.
Dragons are generally popular although, being perfectionists,
can be too direct or demanding of others.”
