#1 – Pyrenean Ibex
Image Source: Extinct Animals
Back in 2003, a team of Spanish scientists attempted to clone a Pyrenean ibex, which is an extinct animal that looks similar to a goat. That was the first Cloning operation for an extinct animal. The scientists harvested nuclei out of Pyrenean ibex cells and then they put that into empty goat egg cells and then into goat surrogate mothers. After many attempts, they had a live ibex. Unfortunately, it lived only for few minutes, but it laid the groundwork for more experiments in the future.
