Horns, Tusks, and Flippers
Since the extinction of the dinosaurs, hoofed mammals have been the planet's dominant herbivores. Native to all continents except Australia and Antarctica, recent paleontological and biological discoveries have deepened understanding of their evolution. This text reveals their evolutionary history.
Polarization Vision and Environmental Polarized Light
This new edition presents a state-of-the-art exploration of polarized light and polarization vision. Part I of the book examines polarization sensitivity across many animal taxa, including invertebrates and vertebrates, and it details both terrestrial and aquatic life. Part II is devoted to the description of environmental polarization with implications to animal and human polarization vision. This includes underwater polarization, polarization signals, sky-polarimetric Viking navigation and astronomical polarization. This part also examines polarized light pollution induced by anthropogenic factors, such as reflection off asphalt surfaces, glass panes, car bodies, and other man-made structures that are now known to form ecological traps for polarotactic insects. The new edition features a number of novelties, including chapters on trilobites, springtails, bats, seals, imaging polarimetry, and astronomical polarization.
Dinosaurs at the Dinner Party
From the bestselling author of The Clockwork Universe and The Writing of the Gods, an “utterly delightful…hugely entertaining” (Air Mail) book about the eccentric Victorians who discovered dinosaur bones, leading to a whole new understanding of human history. In the early 1800s the natural world was a safe and cozy place, or so people believed. But then a twelve-year-old farm boy in Massachusetts stumbled on a row of fossilized three-toed footprints the size of dinner plates—the first dinosaur tracks ever found. Soon, in England, scientists unearthed enormous bones that reached as high as a man’s head. Outside of myths and fairy tales, no one had even imagined that creatures like three-toed giants had once lumbered across the land—nor dreamed that they could all have vanished, hundreds of millions years ago. In Dinosaurs at the Dinner Party, celebrated storyteller and historian Edward Dolnick leads us through a compelling true adventure as the paleontologists of the early 19th century puzzled their way through the fossil record to create the story of dinosaurs we know today. The tale begins with Mary Anning, a poor, uneducated woman who had a sixth sense for finding fossils buried deep inside cliffs; moves to William Buckland, an eccentric geologist who filled his home with specimens and famously pieced together a prehistoric scene from the fossil record inside a cave; and then on to the controversial Richard Owen, the era’s best-known scientist, and the one who coined the term “dinosaur.” “Exuberant” (Kirkus Reviews), entertaining, erudite, and featuring an unconventional cast of characters, Dinosaurs at the Dinner Party tells the story of how the accidental discovery of prehistoric creatures upended humanity’s understanding of the world and its own place within it.
