The Armley Hippo, previously known as the Leeds Hippopotamus, is the greater part of the fossil skeleton of a great northern hippopotamus (Hippopotamus amphibius) consisting of 122 bones, of which 25 were taxidermy-mounted in 2008 by James Dickinson for display at Leeds City Museum in Leeds, West Yorkshire, England. The skeleton may be as much as 130,000 years old. The species it represents has been extinct in the United Kingdom since prehistoric times.
