1. The Science of Ice Age 4: Continental Drift
The Science of Ice Age 4:
Continental Drift

2. What IS continental drift??

4. And what about the Ice Age??

5. The last ice
age!!
20,000
years
ago…

7. PRESENT PAST

8. What about the animals??

9. MANNY
..is a mammoth
They lived from 5
million years ago
But were still alive
3,000 years ago in
Russia: 7,000
years after the last
Cool fact: although some were very big (4m tall)
most were the size of an Asian elephant, their ice age!!
closest living relative…

10. They are extinct partly because of climate change and partly because of hunting by man.
They are often very well preserved….

11. Diego
..is a Smilodon (or
sabre-toothed cat)
They lived from
2.5 million years
ago in the
Americas
They died out
10,000 years ago

12. Cool fact: Smilodons were massive (S populator exceeded half a tonne – much bigger than
a tiger) and genetically very different from living cats: more like half way to a hyaena!

13. Sid
..is a Magalonyx
or ground sloth
They lived from 10
million years ago
in the Americas
Cool fact: Sid’s closest living relative is the two-toed sloth…
They died out
10,000 years ago

14. Sid is small in the
film – but some
Megalonyx were
massive – 3m tall
and lived on the
ground, not in
trees…
We can still find
their fossilised poo
(coprolytes) in caves
in South America!!

15. Today you will meet –
Gutt!!
He is a giant ape -
Gigantopithecus
They lived from 9
million years ago in
Asia: we know very
little about them!
Cool fact: Gutt could never have met Sid They died out 100,000
or Diego on land – they lived on different
continents! years ago

16. And finally, what on EARTH am I??

17. Scrat
.. Was described
as a sabre-toothed
squirrel in 2002
when the film Ice
Age 1 was
released….
BUT no such
animal was known
to exist….
Sabre teeth!!

18. However….
In 2011, scientists discovered the fossilised remains of a sabre-
toothed squirrel in Patagonia, South America !! The film-makers
guessed right…
The catch???

19. 93 million years ago…
He’s too old
to have met
any of the
other
characters!!!

20. ENJOY THE FILM!!
