Sebastian Klein takes you up close to lizards and beasts from the past.
Have you ever wondered what it was really like back then?
How the world looked, how the animals looked and how the animals lived.
Try and imagine if you opened your window in the morning and a large long-necked snake just walked out in front of your window.
That would be kind of crazy, wouldn't it?
Here you can learn about the very latest research in dinosaurs - and Sebastian Klein has been lucky enough to get his hands on it.
It's really exciting reading and it's hugely fascinating to think that such huge animals once lived.
So you can look forward to it!
