Just been doing a little searching around on Zootierlist, and it mentions under 'former holdings' for Quagga that Knowsley has had them. Considering that Knowsley Safari Park started in 1971 and the Quagga went extinct in 1883, there is an apparant problem here. Has Zootierlist made a massive mistake, or is there more to it?
