Takes a tour of the Earth three hundred and twenty million years ago, during the Paleozoic Era, and investigates the plants and animals found there.

Takes a tour of the Earth three hundred and twenty million years ago, during the Paleozoic Era, and investigates the plants and animals found there.

Take a fun, fact-filled trip back to Earth as it was 430 million years ago. Then, watch as continents drift and oceans take shape. Watch out (!) as fish get toothier, plants stretch skywards and bugs get bigger. Soon fish get feet and four-legged creatures stalk the planet. Here’s the story of Earth in conversational text, informative illustrations, and humorous cartoons. Complete with time line, pronunciation guide, glossary and index.

In the style of WHEN BUGS WERE BIG and WHEN FISH GOT FEET this book discusses all the exciting developments of the Triassic Age, from the recovery of the planet from the most deadly mass extinction ever, to the first appearance of the dinosaurs. We also get to meet the first mammals, the first pterosaurs (flying reptiles), the first frogs, a host of predatory marine reptiles, early turtles, and the first coral reefs. With the books' signature blend of humor and clearly presented information, cartoon illustrations help keep the fact-filled material extra fun.

Illustrations and nimble prose bring these ancient creepy-crawlies-and their tamer relatives- to life with scientific detail.

Sure you know T-Rex was the meat-eating king and brontosaurus munched on leaves, but what else was on the dino dining menu during the Mesozoic era? Meet the 'vores: carnivores, piscivores, herbivores, insectivores, "trashivores," "sunivores," and omnivores like us. Readers will be surprised and inspired to learn about dino diets and they'll get to explore how scientists can tell which dinosaurs ate what just from looking at fossils! Journey through artist and author Hannah Bonner's whimsical world to learn how the dinosaurs and their contemporaries bit, chewed, and soaked up their food.

Previously published as three volumes-- When fish got feet, sharks got teeth, and bugs began to swarm; When bugs were big, plants were strange, and tetrapods stalked the earth; and When dinos dawned, mammals got munched, and pterosaurs took flight.

This groundbreaking book reveals that, far from being sluggish reptiles, dinosaurs were actually agile, fast, warm-blooded, and intelligent. The author explodes the old orthodoxies and gives us a convincing picture of how dinosaurs hunted, fed, mated, fought and died.Containing over 200 detailed illustrations, The Great Dinosaur Debate will enthrall "dinosaurmaniacs". It is a bold new look at the extraordinary reign and eventual extinction of the awesome behemoths who ruled the earth for 150 million years. Copyright © Libri GmbH. All rights reserved.

This book covers advances made since the 2004 Springer volume “Polarized Light in Animal Vision” edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopies; normal and anomalous polarization patterns of the skies; skylight polarization transmitted through Snell’s window and both linearly and circularly polarized signals produced by terrestrial and aquatic animals. 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. Part III surveys some of the practical applications of polarization vision including polarization-based traps for biting insects, ground-based polarimetric cloud detectors and an historical examination of the navigational abilities of Viking seafarers using the sky polarization compass. The deterrent qualities of ungulate pelage to polarization-sensitive biting insects is also examined in this section.

This book introduces young readers to insects with more than 100 pictures, an explorer's corner with from-the-field anecdotes and tips, fun facts throughout, maps and infographics, an illustrated diagram, a photo gallery, cool comparisons, a behind-the-scenes photograph, an interactive glossary, and more.--
