- 1 Dinosaurs belong to a group
of giant reptiles that became extinct about 65 million years ago. 2 These
creatures existed for more than 175 million
years, and dinosaur fossils on every continent except Antarctica have been
found. 3 The brachiosaurus was the largest whose weight is estimated at
50 to 70 tons. 4 Scientists could not for many years agree on the cause
of extinction; many believed that the massive size of the creatures was
responsible for their disappearance. 5 However, this theory was discarded
because fossil remains have revealed that not all dinosaurs were big. 6
As scientists discovered more about the Earth's history, they learned that
many other forms of life came also to a sudden end about the same time that
the dinosaurs died off. 7 Heavy metal concentrations at certain levels of
sedimentary rock provide the basis for the recent most explanation of the
extinction of dinosaurs. 8 According to this theory, if a meteorite had
hit the Earth with a diameter of six miles, it would have formed a giant
crater, and then it would have disintegrated. 9 But first, it would have
created a dust cloud that might have blocked for months the sun. 10 Plants
would have died without the sun's energy, and animals too would have died.
11 Lack of sunlight would have brought also unusually cold weather that
might have killed any of the remaining animals. 12 Today, biologists believe
that a disaster of this kind is the most plausible explanation for the disappearance
sudden of dinosaurs.
