	When Professor Challenger is finally ready,
perhaps I might continue?
:06:06
	Carry on, Professor.
:06:11
	The very word dinosaur,
meaning "terrible reptile", tells us...
:06:16
	...this is a vertebra from a creature
known as Iguanodon bernissartensis.
:06:24
	Behind me is an artist's impression
of the iguanodon,
:06:28
	which stood on its hind legs
in the manner of a kangaroo.
:06:31
	Oh, come on! A kangaroo?
Are you sure? Have you ever seen one?
:06:37
	Don't be absurd!
No one's ever seen a dinosaur.
:06:41
	(LAUGHTER)
:06:42
	The great size of these creatures
was paradoxically their weakness,
:06:46
	for the dinosaurs could not compete
with the smaller and more agile mammals.
:06:52
	Where's his proof?
:06:55
	The proof is that we are here and dinosaurs
are remarkably thin on the ground.
:06:59

	Professor Summerlee...
:07:05
	...I wonder if you would be kind enough
to identify something for me.
:07:11
	I will take questions at the end.
:07:14
	(CHALLENGER) I'm sure you will.
Let's have a look at this first.
:07:21
	Now...
:07:23
	...what do you make of that?
:07:30
	It appears to be
a remarkably well-preserved fossil
:07:34
	of the forearm of a pterosaur,
a flying reptile of the Mesozoic period.
:07:40
	But it isn't a fossil, is it?
:07:45
	There's something up here.
Make sure you get all this down.
:07:49
	Must be a fake.
:07:52
	Clever, undoubtedly, but a fake.
:07:56
	This bone came from an animal...
