Hyraceum

Hyraceum ( /haɪərˈreɪsiəm/) is the petrified and rock-like excrement composed of both urine and feces excreted by the Cape Hyrax, (Procavia capensis), commonly referred to as the Dassie. After aging and petrifying over hundreds if not thousands of years, it is a sought-after material that has been used in both traditional South African medicine and perfumery.
