Like historical dioramas, natural history dioramas are a mix of two- and three-dimensional elements. What sets natural history dioramas apart from other categories is the use of taxidermy in addition to the foreground replicas and painted background. The use of taxidermy means that natural history dioramas derive not only from Daguerre's work, but also from that of taxidermists, who were used to preparing specimens for either science or spectacle. It was only with the dioramas' precursors (and, later on, dioramas) that both these objectives merged. Popular diorama precursors were produced by Charles Willson Peale, an artist with an interest in taxidermy, during the early 19th century. To present his specimens, Peale "painted skies and landscapes on the back of cases displaying his taxidermy specimens". By the late 19th century, the British Museum held an exhibition featuring taxidermy birds set on models of plants.
