A group of extinct Irish elk from the Ice Age – part of a series of models of extinct animals created by sculptor and fossil expert Benjamin Waterhouse Hawkins and Professor Richard Owen, founder of the Natural History Museum, in the 1850s for the park surrounding the reconstructed Crystal Palace, known as Crystal Palace Park. Built for the Great Exhibition of 1851 by Joseph Paxton, the palace had been relocated from Hyde Park to Sydenham, in what was Kent (and is now south London), following the exhibition’s closure. The series of life-sized extinct animals, initially just mammals but later expanded to include dinosaurs, underwent extensive restoration in 2002 and were given Grade I listed status in 2007. There’s a free audio guide you can download while visiting the dinosaurs. PICTURE: Neil Cummings/Flickr/CC BY-SA 2.0.
