Today’s topic is a big one---it’s dinosaurs, those strange creatures whichruled the earth for no less than two hundred million years, some of them were plant eaters, others were like the infamous Tyrannosaurus Rex, a carnivores who lived off meat and who attacked the more peaceful plant eating dinosaurs. Not all dinosaurs were big --- some were the size of chickens , and in fact the closest
things to dinosaurs living today are actually birds. But the mystery we are going to talk about today is why the dinosaurs suddenly disappeared exactly 66 million years ago, and to throw light on the subject we’ve invited one of the world’s foremost
experts on the subject, from the Pitt Rivers Museum in Oxford, Dr Roger Binfield. Listening 2

( )FTPresenter:Good afternoon Dr Binfield,
and welcome to the programme.
Dr?Binfield:Thank you.
Presenter:I'm going to come straight to
the point, even if I think there's not
going to be an easy answer: why did
the dinosaurs suddenly disappear,
almost overnight, 66 million years ago?
Dr Binfield: You're right. There's no easy answer to that question, but there are lots of theories.Presenter: Such as?
Dr Binfield: Well, probably the most
widely accepted theory is the
meteorite one...
Presenter: You mean the earth was
hit by a meteorite from space?
Dr Binfield: Yes, that's right.
Presenter: And the dinosaurs died
immediately?Dr Binfield:Not exactly, not all of them.
The meteorite may have hit the earth
with such force that it created a huge
dust cloud, which stopped the sunlight
from getting through... so there was no
light, no heat, and no food.
Presenter:But other animals survived?
Dr Binfield:Yes, smaller creatures like
mammals, which may have survived
because they ate nuts and seeds.
Presenter:What other theories are there?
Dr Binfield:Lots. The dinosaurs may have stopped evolving, and been unable to adapt to changes in the climate. Or they might all have killed each other.
Presenter:Is that possible?
Dr Binfield: Oh yes. They spent a lot of time fighting. There again, it might have been volcanic eruptions, not a meteorite, which sent up clouds of dust and cut off the light. One very recent theory says they died of cancer.
Presenter: Cancer? You mean the dinosaurs died out because they fell ill?
Dr Binfield: Yes. As a result of radiation coming from a dying star somewhere in our galaxy...
Presenter: That sounds fantastic.
Dr Binfield: Well, I think it's unlikely, but it's not impossible.
Presenter: Which theory do you believe?
Dr Binfield: I'd go for the meteorite. I think it's the most likely one. And in fact there is a huge crater in the Caribbean sea, off the coast of Mexico, where the meteorite may have landed...1. If you can adapt to something, you
can change in order to make the situation better.
