This authoritative volume brings together decades of insights from one of the longest terrestrial fossil records on the planet.
The fabled Himalayas have isolated and sheltered the Indian subcontinent for millions of years. The Siwalik sequence of sediments at their feet has been a treasure trove of visions into the past for generations of palaeontologists, preserving an immense 20 million years of terrestrial ecosystems' fossil record. The Siwalik sequence reveals a unique forest wonderland of diverse animal species: from huge elephant relatives, great rhinos, and sabertooth cats, to mongooses, swamp rats, crocodiles, and catfish. Regional climate change eventually caused this forest ecosystem to unravel, as grasslands replaced the forests and established the habitats and animals of the modern ecosystems of the Indus and Ganges rivers.
In At the Foot of the Himalayas, celebrated palaeontologists Catherine Badgley, Michele Morgan, and David Pilbeam bring together a collection of world-renowned scholars to present an interdisciplinary approach to documenting and interpreting this fossil record. By investigating changes in landscape, climate, and vertebrate species diversity, their analysis reveals insights into a central question about biodiversity: which evolutionary developments were influenced by changes in climate, and which were caused by interactions among the species themselves? This groundbreaking book illuminates for the first time a mysterious and vibrant palaeontological past, bringing together more than 40 years of exciting international collaborative studies that forge invaluable knowledge pathways for the ecologists, evolutionary scientists, and palaeontologists of the future, and pose important questions about our fragile ecosystems in the present day.

"An astonishing achievement. A beautifully integrated, multidisciplinary synthesis for a wide audience, an excellent introduction to terrestrial paleontology of the Cenozoic, a treasure trove for the specialist, a mesmerizing slow read for the connoisseur. Also a unique story, lovingly told by its participants, many of whom have been there since it all began fifty years ago. For me, a candidate for the book of the decade."

"As with a crucial fossil encased in rocky matrix, preparation of this monograph has been eagerly anticipated. Initial observations presaged its central importance to paleobiology, but this final cleaning and assembly reveals the sweeping implications of the Siwaliks project: questions it answers and cannot answer, and new questions we never thought to ask."
