Pyrenean Ibex
From RationalWiki
The Pyrenean Ibex is a type of extinct goat, chiefly notable for being the first species ever to become un-extinct through cloning. However, it rather quickly became re-extinct when the only live birth died of breathing difficulties. The scientists at the University of Zaragoza where the cloning was carried out have yet to release a statement on what Ibex curry tastes like.
Ibex was traditionally served with an accompaniment of beetroot.[1][2]
