In a series of comparative studies published from 1821 to 1838, and collected under the title Die vergleichende Osteologie [The Comparative Osteology], the Baltic German biologist Heinz Christian Pander (1794–1865) and the Italian-born German naturalist and artist Edouard Joseph d’Alton (1772–1840) presented an extraordinary illustrated atlas of animal bones.

The diverse range of animals the work covers (or rather uncovers) include elephants and hippopotamuses, hyenas and polar bears, giraffes and camels, porcupines and red squirrels, as well as the extinct megatherium or giant ground sloth. They are depicted both as complete skeletons inside a silhouette of the living animal and also in separate studies of individual skulls and other bones.
