8. Pyrenean Ibex (Capra pyrenaica pyrenaica)
The Pyrenean ibex was a wild goat native to the rugged mountains between France and Spain. Its extinction in 2000 was marked by the tragic death of the last individual under a fallen tree. In a remarkable turn, scientists attempted cloning in 2003, briefly reviving the species—only for the clone to die shortly after birth. This made the ibex the first species to go extinct twice.
