Dinosaurs lived long ago. Other animals lived long ago, too.
This is a mammoth. It is a big animal. It lived long ago. It lived in the ice age. There are no mammoths now. They are extinct.
This is an elephant. It is a big animal. It lives now. A mammoth is like an elephant. But, they are not the same.
Elephants are grey. Mammoths were brown. Elephants have big ears. Mammoths had small ears. Elephants have skin. Mammoths had woolly fur.
Elephants have small tusks. Mammoths had big tusks. Elephants live in warm places. Mammoths lived in cold places. Elephants are big. Mammoths were huge.
This is a dodo. It is a big bird. It lived long ago. There are no dodos now. They are extinct.
The dodo was a cool bird. It could not fly. It was friendly. It had tiny wings. It had a big beak. It had soft grey feathers.
People think dodos were not smart. That is not true. People think dodos were clumsy. That is not true.
This is a sabre-tooth cat. It lived long ago. It lived in the ice age. There are no sabre-tooth cats now. They are extinct.
It looks like a tiger, but it is not a tiger. Sabre-tooth cats were good hunters. They liked to hide, and pounce.
Long ago animals were cool. I want to see a mammoth.
