New Dinosaur Extinction Theory

Subject: New Dinosaur Extinction Theory

For more than a decade, most scientists have believed that the extinction of the dinosaurs was caused by a single event: the crash of an immense body from outer space, its explosive force like a hundred million hydrogen bombs, igniting firestorms and shrouding the earth in a dense cloud of dust that blocked sunlight and sent worldwide temperatures plummeting.

Now, however, scientists working in Ukraine have discovered that a well-known but smaller crater, some 15 miles wide, had been inaccurately dated and is actually 65 million years old, making the blast that created it a likely contributor to the end of the dinosaurs.

So too, a British team has recently found a crater at the bottom of the North Sea dating to the same era and stretching over 12 miles in a series of concentric rings.

The discoveries are giving new support to the idea that killer objects from outer space may have sometimes arrived in pairs or even swarms, perhaps explaining why the extinctions seen in the fossil record can be messy affairs, with species reeling before a final punch finishes them off.
