7) Pyrenean Ibex
The Pyrenean ibex was one of the few—if not the only—animals to actually have been removed from the list of extinct species, albeit very briefly. Endemic to the Iberian Peninsula (including the northern Pyrenees), factors such as the introduction of foreign ungulates (acting as vectors of disease), competition with grazing livestock, and general hunting conflated into a force that overwhelmed Pyrenean ibex populations. But scientists working with a DNA sample recovered from the last known specimen managed to create a genetic clone in 2009. Sadly, the newborn ibex died within seven minutes due to abnormalities in the lungs.
