Thomas Halliday: Otherlands

<div>My guest on this week's Book Club podcast is the palaeobiologist Thomas Halliday, whose book <em>Otherlands: A World In The Making </em>takes us on an extraordinary journey through the whole history of life on earth. Thomas tells me why tyrannosaurus rex didn't eat diplodocus, why if you had to live in a swamp the carboniferous might be a good time to do it, and gives a jaw-dropping sense of what the night sky looked like when the earth was young.</div>
