“When you think of fossils, your mind likely goes straight to dinosaur skeletons and saber-toothed tiger skulls and ancient seashells. In this readable and engaging book, Dale Greenwalt introduces us to less heralded fossils: microscopic molecules like DNA, proteins, and pigment. Through his relatable prose and stories of discovery, Greenwalt convincingly argues that some of the smallest fossils have the biggest stories to tell.”—Steve Brusatte, New York Times bestselling author of The Rise and Fall of the Dinosaurs

“In Remnants of Ancient Life, Dale Greenwalt takes readers on a grand tour through our deepest history, guided by the tiniest of fossils. Engaging and personable, this book offers a fascinating discussion of the latest developments and discoveries in paleontology.”—Beth Shapiro, author of How to Clone a Mammoth

“If your perception of paleontology is stuck in the past, you need to read this book. Dale Greenwalt takes readers on a far-ranging expedition with biochemical fossil hunters who use trace elements, pigments, proteins, and DNA to reconstruct not only evolutionary lineages but the colors, diets, and behavior of long-vanished organisms—conjuring them out of rocks and back to life.”—Marcia Bjornerud, author of Timefulness

“Remnants of Ancient Life takes readers on a spirited tour of paleontology’s new frontier—ancient molecules preserved within fossils and sediments. From dinosaur behavior and the feeding strategies of extinct insects to the evolutionary relationships of mammoths and previously unknown cousins of Neanderthals, Greenwalt shows how ancient molecules are providing novel insights into our biological past.”—Andrew H. Knoll, author of A Brief History of Earth
