This chance encounter in the basement of the Natural History Museum of Los Angeles County sparked Troll’s obsession with Helicoprion, a mysterious monster from deep time.In 2010, tattooed undergraduate student and returning Iraq War veteran Jesse Pruitt became seriously smitten with 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 mysterious 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.

We are fascinated by the daily lives of our fellow creatures--how they reproduce and raise their young, how they hunt their prey or elude their predators, and more. What would it be like to see prehistoric animals as they lived and breathed?From dinosaurs fighting to their deaths to elephant-sized burrowing ground sloths, this book takes readers on a global journey deep into the earth's past. Locked in Time showcases fifty of the most astonishing fossils ever found, brought together in five fascinating chapters that offer an unprecedented glimpse at the real-life behaviors of prehistoric animals. Dean R. Lomax examines the extraordinary direct evidence of fossils captured in the midst of everyday action, such as dinosaurs sitting on their eggs like birds, Jurassic flies preserved while mating, a T. rex infected by parasites. Each fossil, he reveals, tells a unique story about prehistoric life. Many recall behaviors typical of animals familiar to us today, evoking the chain of evolution that links all living things to their distant ancestors. Locked in Time allows us to see that fossils are not just inanimate objects: they can record the life stories of creatures as fully alive as any today. Striking and scientifically rigorous illustrations by renowned paleoartist Bob Nicholls bring these breathtaking moments to life.
