Megalodon and Other Prehistoric Sharks by Tammy Gagne Pdf
"Great white, bull, and tiger sharks are some of today's most talked-about sharks. But have you met the sharks of yesterday? Each prehistoric shark had its own amazing-and sometimes strange-features. The scissor-tooth shark had teeth in a spiral shape. The giant megalodon was about three times the size of a great white. One small prehistoric shark had a big dorsal fin in the shape of an ironing board! Readers will gobble up all the facts about these early ocean hunters and learn how they compare to modern sharks"--

Today we are going to take a step back in time and enter a long-gone age. 1.5 million years ago there lived thousands of animals that are now extinct. “Extinct” means that they no longer exist. These extinct animals are some of the most intriguing and awe-inspiring animals that have existed on our planet. Their colossal size, strange characteristics, and mysterious disappearance make them inherently worthy of study and interest. Even more than these reasons, the study of these ancient animals itself is an incredible adventure which requires intense thought and a vivid imagination. The study of ancient animals helps you to appreciate just how mysterious and amazing our planet really is. Our planet supports not only us and the animals that live today, but it even supported creatures as gigantic and strange as the dinosaurs- just think how cool that is! I hope that you bring a spirit of openness and wonder to your study of ancient animals, and that you come to appreciate the mystery and value of the natural world. The animal we are going to talk about is a species of giant shark called Megalodon that lived during a period which coincided with the Age of the Mammals. We are going to discuss all this and more in the chapters that follow. The Megalodon was the largest predator to ever exist on the planet earth. It is a popular animal because of its immense size, power, and because it is a shark! We know what we know about ancient animals from a variety of sources including fossils, biology, and other scientific disciplines. Fossils are the ancient remains of the dinosaurs, the most familiar being their bones. Biological science is the study of life in general, but many scientists compare the ancient animals to modern day animals to support their theories. The fossils of the Megalodon are mostly relegated to its teeth. We have very few other Megalodon fossils and we will talk about this later. Before a talk about extinct animals can take place it is important that we discuss the theory of evolution. Evolutionary theory supposes that all the animals we know and see today are the direct descendants of animals that existed millions of years ago. The dinosaurs and other creatures that existed millions of years ago either died out or gradually changed into different animals. For instance, birds are considered to be surviving dinosaurs because their dinosaur ancestors survived the dinosaur extinction event (we will discuss this later). The sharks we know today are descended from the Megalodon and other related mega-sharks.

From ancient megalodons to fearsome Great Whites, this book tells the complete, untold story of how sharks emerged as Earth’s ultimate survivors, by world-leading paleontologist John Long. “Will keep you on the edge of your seat from its first page to its last page.”—Jared Diamond, Pulitzer Prize–winning author of Guns, Germs, and Steel Sharks have been fighting for their lives for 500 million years and today are under dire threat. They are the longest-surviving vertebrate on Earth, outlasting multiple mass extinction events that decimated life on the planet. But how did they thrive for so long? By developing superpower-like abilities that allowed them to ascend to the top of the oceanic food chain. John Long, who for decades has been on the cutting edge of shark research, weaves a thrilling story of sharks’ unparalleled reign. The Secret History of Sharks showcases the global search to discover sharks’ largely unknown evolution, led by Long and dozens of other extraordinary scientists. They embark on digs to all seven continents, investigating layers of rock and using cutting-edge technology to reveal never-before-found fossils and the clues to sharks’ singular story. As the tale unfolds, Long introduces an enormous range of astonishing organisms: a thirty-foot-long shark with a deadly saw blade of jagged teeth protruding from its lower jaws, a monster giant clams crusher, and bizarre sharks fossilized while in their mating ritual. The book also includes startling new facts about the mighty megalodon, with its sixty-six-foot-long body, massive jaws, and six-inch serrated teeth. With insights into the threats to sharks today, how they contribute to medical advances, and the lessons they can teach us about our own survival, The Secret History of Sharks is a riveting look at scientific discovery with ramifications far beyond the ocean.

Internationally bestselling author and renowned scientist Tim Flannery and his daughter, scientist Emma Flannery, delivers an informative-yet-intimate portrait of the megalodon, an extinct shark and the largest predator of all time When Tim Flannery was a boy he found a fossilized tooth of the giant shark megalodon at a beach near his home in Australia. This remarkable find—the tooth was large enough to cover his palm—sparked an interest in paleontology that was to inform his life’s work and a lifelong quest to uncover the secrets of the great shark Otodus megalodon. Tim passed on his love of the natural world and interest in the fossil record to his daughter, Emma, a scientist and writer. And now, together, they have written a fascinating account of this ancient marine creature. Big Meg charts the evolution of megalodon, its super-predator status for about fifteen million years and its decline and extinction. It delves into the fossil record to answer questions about its behavior and role in shaping marine ecosystems as well as its impact on the human psyche. It contains stories of the scientist and amateur fossil hunters who have scoured the seas, and land, for fossil remains, drawn to the beauty and mystique of the great shark, sometimes meeting their death in the process. Deemed “in the league of the all-time great explorers” by David Attenborough, Tim Flannery has come together with Emma Flannery to spin a story of the great natural history of our planet as enthralling as the fossil record itself.
Sharks and dinosaurs--we find them both alien and awe-inspiring. This book is a plunge into the Cretaceous oceans of 80 million years ago, a merciless realm ruled by the most ferocious animals ever to stalk the seas of planet Earth. More terrifying than anything known to humankind, it scarcely seems possible that these swift, massive underwater predators actually existed--but they did. The book interweaves dramatic scenes of the far, far distant past; scientific profiles of nearly two dozen sea monsters; and a group portrait of the eccentric Sternberg family, Kansas-bred pioneers of marine paleontology. From giant sharks and fierce reptiles to the fossil-hunters who proved that today's land-locked Great Plains were once submerged, this book will forever change how we think about marine predators.--From publisher description.
A prehistoric mystery. A fossil so mesmerizing that it boggled the minds of scientists for more than a century—until a motley crew of modern day shark fanatics decided to try to bring the monster-predator back to life. In 1993, Alaskan artist and paleo-fish freak Ray Troll stumbled upon the weirdest fossil he had ever seen—a platter-sized spiral of tightly wound shark teeth. This chance encounter in the basement of the Natural History Museum of Los Angeles County sparked Troll's obsession with Helicoprion, a mysterious monster shark from deep time. In 2010, tattooed amateur strongman and returning Iraq War veteran Jesse Pruitt was also severely smitten by a Helicoprion fossil in a museum basement in Idaho. These two bizarre-shark disciples found each other, and an unconventional band of collaborators grew serendipitously around them, determined to solve the puzzle of the tooth whorl once and for all. Helicoprion was a Paleozoic chondrichthyan about the size of a modern great white shark, with a circular saw of teeth centered in its lower jaw—a feature unseen in the shark world before or since. For some ten million years, long before the Age of Dinosaurs, Helicoprion patrolled the shallow seas around the supercontinent Pangaea as the apex predator of its time. Just a few tumultuous years after Pruitt and Troll met, imagination, passion, scientific process, and state-of-the-art technology merged into an unstoppable force that reanimated the remarkable creature—and made important new discoveries. In this groundbreaking book, Susan Ewing reveals these revolutionary insights into what Helicoprion looked like and how the tooth whorl functioned—pushing this dazzling and awe-inspiring beast into the spotlight of modern science
