About this book
Ammonites swam in Earth’s ancient seas for nearly 400 million years. These prolific cephalopods diversified into more than 10,000 species before meeting their demise during the end-Cretaceous mass extinction. Today, these spiral-shelled invertebrates are among the most abundant fossils in the geologic record, found from snowcapped Himalayan peaks to parched South American arroyos. People around the world have long been drawn to the mystery and beauty of ammonite fossils. These preternaturally preserved creatures have inspired age-old myths and legends, and studying their secrets has spurred crucial scientific discoveries.
Jodi Summers—an accomplished journalist and passionate fossil collector—guides readers through the entire arc of ammonite history. She explores the evolution, proliferation, extinction, and fossilization of these captivating cephalopods, situating the story in the progression of deep time. Summers also prospects prime fossil-hunting locations, sharing tips, export legalities, and inside scoops for enthusiasts and collectors in search of notable specimens. She takes us along on her globe-spanning journeys: from the desert to the seashore, up mountains and down canyons, to the backrooms of natural history institutions and the floors of fossil shows.
We Dig Ammonites features hundreds of lavish color photographs of rare specimens that showcase the splendor of these magnificent molluscs. This book is an ode to one of the world’s most compelling fossils and an invitation to catch a glimpse of vanished epochs.
