Through a close study of fossil records, Halliday describes what day-to-day existence must have been like for plants and animals, beginning with the Pleistocene ice age, then moving backwards in time through different geologic epochs. In his new book, Otherlands: A Journey through Earth’s Extinct Worlds, paleontologist Thomas Halliday offers a close-up, in-depth survey of life on our planet, long before mankind came along and started bending natural laws to its will. ![]() These days, with advances in paleontology and evolutionary biology, we have a far better-informed answer to this question.
