The clip grampas' story from The Land Before Time (1988) with Pat Hingle
beneath this same sun,
long before you...
before the ape and the elephant as well,
before the wolf, the bison, the whale,
before the mammoth and the mastodon
in the time of the dinosaurs.
Dinosaurs were of two kinds-
Some had flat teeth and ate the leaves of trees.
Some had sharp teeth for eating meat.
They preyed upon the leaf-eaters.
Then leaves began to die.
The mighty beasts, who appeared to rule earth,
were ruled, in truth, by the leaf.
Desperate for food,
some dinosaur herds struck out toward the west,
searching for their Great Valley,
a land still lush and green.
It was a journey toward life.
It was a march of many dangers.
Sharpteeth stalked the herds,
waiting to seize any who strayed.
The leaf-eaters stopped only to hatch their young.
