This Web site is offered through C. Campbell's Natural Worlds, a "completely nonprofit, education online series which exists as a means of providing detailed information on a variety of topics within the natural history field." The Thylacine Museum, not surprisingly, is devoted to the now extinct thylacine (also known as the Tasmanian tiger). The site includes "information covering virtually all aspects of this very unique Australian marsupial." Users can browse dozens of pages of detailed articles about these animals. Topics covered include thylacine behavior, fossil record, skull data, and much more. The site also offers photos and movie clips of captive thylacines from the first part of the 20th century. Owing to this Web site's high level of detail and extensive text, the casual visitor may not find this site readily appealing. However, anyone with even a remote interest in thylacines or Australian mammals in general should appreciate this extremely comprehensive resource.
