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, palaeontologist Elsa Panciroli charts the emergence of the mammal lineage, Synapsida, beginning at their murky split from the reptiles in the Carboniferous period, over three hundred million years ago. They made the world theirs long before the rise of dinosaurs. Travelling forward into the Permian and then Triassic periods, we learn how our ancient mammal ancestors evolved from large hairy beasts with accelerating metabolisms to exploit miniaturisation, which was key to unlocking the traits that define mammals as we now know them.
Elsa criss-crosses the globe to explore the sites where discoveries are being made and meet the people who make them. In Scotland, she traverses the desert dunes of prehistoric Moray, where quarry workers unearthed the footprints of Permian creatures from before the time of dinosaurs. In South Africa, she introduces us to animals, once called 'mammal-like reptiles', that gave scientists the first hints that our furry kin evolved from a lineage of egg-laying burrowers. In China, new, complete fossilised skeletons reveal mammals that were gliders, shovel-pawed Jurassic moles, and flat-tailed swimmers.
This book radically reframes the narrative of our mammalian ancestors and provides a counterpoint to the stereotypes of mighty dinosaur overlords and cowering little mammals. It turns out the earliest mammals weren't just precursors, they were pioneers.

Prefazione
This is the story of our most ancient of ancestors: mammals. This book reframes the narrative of mammal evolution, and proves they weren't just precursors, they were pioneers.
Testo aggiuntivo
Provides a fascinating and uplifting look at the resilience of life on this planet, through the lens of how mammals came to be.
