Winter in Eden

The great reptiles were the most successful life forms ever to populate this world. For 140 million years they ruled the Earth, filled the sky, swarmed in the seas. At this time the mammals, the ancestors of mankind, were only tiny, shrew-like animals that were preyed upon by the larger, faster, more intelligent saurians.

Then, 65 million years ago, this all changed. A meteor six miles in diameter struck the Earth and caused disastrous atmospheric upheavals. Within a brief span of time over seventy-five percent of all the species then existent were wiped out. The age of the dinosaurs was over; the evolution of the mammals that they had suppressed for 100 million years began.

But what if that meteor had not fallen?

What would our world be like today?
