Now what the family didn't know,or anyone else on Earth either,is that the Moon is 65 million years
old.
Slightly older then the impact of the asteroid that supposedly wiped out the dinosaurs.
And the Moon,a half mile or so below its surface,is composed of hollow caverns,tunnels and the like.
So the Zoo staff,being el cheapo's,had built a time portal to a period slightly before the impact of
the asteroid.
Besides saving money on time travel mileage charges,it also meant any interference
from future visitors such as the family
on the past was not a problem,since
the asteroid would vapourize any alterations to the time line.
So the portal faded away and the family were standing there,watching the various feeble minded dinosaurs do their thing.
They didled about for several hours taking pictures like tourists.
Night fell and they witnessed the glorious ascension of 10 Moons over the nightsky.
"Our" Moon and 9 Brachiosaur designed and built Kinetic-drive Roaming Astro-ships ( KRA = Ark )
They didn't have much time to register this fact when the nearest craft
began shooting multiple tunnels of light
into the area,and the horrified family watched as a pterodactyl
caught in one of the beams that was relentlessly
pursuing the stupid flapping reptile
was atomized and its particles swept up into
the heavens,on a journey to that spaceship lifeboat.
The transport atomizing tunnel lights swept about ,hauling the dinosaurs
in the region into
Brachiosaur Life Craft # 6
Then the tunnel beams suddenly swept over the family and their screams of terror were
swiftly silenced as the Sentient Brachiosaur seeking "light ropes"
atomized them and hauled them aboard...
