Cutting-edge techniques across biology, chemistry, physics, and geology have transformed our understanding of the deep past, including the discovery of a previously unknown mass extinction. This compelling evidence, revealing a series of environmental crises resulting in the near collapse of life on Earth, illuminates our current dilemmas in exquisite detail.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

For most of us, the story of mammal evolution starts after the asteroid impact that killed the dinosaurs, but over the last 20 years, scientists have uncovered new fossils and used new technologies that have upended this story. In Beasts Before Us, paleontologist Elsa Panciroli charts the emergence of the mammal lineage, Synapsida, beginning at their murky split from the reptiles in the Carboniferous period, over 300 million years ago. They made the world theirs long before the rise of dinosaurs.

Many of us know that the Moon pulls on our oceans, driving the tides, but did you know that it smells like gunpowder? Or that it was essential to the development of science and religion? Acclaimed journalist Rebecca Boyle takes listeners on a dazzling tour to reveal the intimate role that our 4.51-billion-year-old companion has played in our biological and cultural evolution.

With its quaint villages, local restaurants serving up lobster rolls, and miles and miles of warm, sandy beaches, Cape Cod, Massachusetts, is famous for being America’s carefree seaside getaway. But in August 2012, the first confirmed shark attack in almost eighty years occurred in the region. As shark sightings quickly began to increase on Cape Cod and elsewhere and large beachside billboards warning about the growing shark population became a common sight, a boogie boarder died after being attacked by a great white shark in Cape Cod’s shallow waters.

Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later.

In this remarkable, groundbreaking audiobook, a documentarian and conservationist, determined to dispel misplaced fear and correct common misconceptions, explores in-depth the secret lives of sharks - magnificent creatures who play an integral part in maintaining the health of the world’s oceans and ultimately the planet.

For centuries, humans ignored sound in the “silent world” of the ocean, assuming that what we couldn’t perceive, didn’t exist. But we couldn’t have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with the temperature and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.
