The Crystal Palace Dinosaurs are probably one of London’s better-kept secrets. This unlikely collection of life-size outdoor sculptures of some 30 prehistoric creatures—including dinosaurs, marine reptiles, and extinct mammals—has survived in the city’s southeast for almost 170 years. They have been lampooned for being terribly outdated in light of what we know today. But that does them no justice. In this gorgeously illustrated book, palaeontologist and palaeoartist Mark Witton has teamed up with Ellinor Michel, an evolutionary biologist and chair and co-founder of the Friends of the Crystal Palace Dinosaurs charity. Together, they chart the full story of the inception, planning, construction, reception, and survival of the sculptures. Foremost, it shows how cutting-edge they were back then, why they still matter today, and why they need our help.
