When I was a kid, I wanted to learn everything I could about the Sabertooth Tiger. This book would have been my go-to book. See the cousins of Sabertooth cats, the marsupial version of a Sabertooth and illustrations of strange animals that Ice Age cats might make into a meal. With a life-size illustration of a Sabertooth's canine you'll see how wimpy the modern tiger's canine looks in comparison.
Side note: This book turned a reluctant reader into a voracious one! A boy at work who was in foster care hadn't properly learned to read. His new foster mom borrowed this book from the library & he became completely absorbed. It was the 1st book he read on his own from cover to cover and it got him going on a reading kick.
