The Age of Mammals

When people today hear “paleontology,” they immediately think of dinosaurs. But for much of the history of the discipline, dramatic demonstrations of the history of life focused on the developmental history of mammals. The Age of Mammals examines how nineteenth-century scholars, writers, artists, and public audiences understood the animals they regarded as being at the summit of life. For them, mammals were crucial for understanding the formation (and possibly the future) of the natural world. Yet, as Chris Manias reveals, this combined with more troubling notions: that seemingly promising creatures had been swept aside in the “struggle for life,” or that modern biodiversity was impoverished compared to previous eras. Why some prehistoric creatures, such as the saber-toothed cat and ground sloth, had become extinct, while others seemed to have been the ancestors of familiar animals like elephants and horses, was a question loaded with cultural assumptions, ambiguity, and trepidation.
