The northern bald ibis (Geronticus eremita) was thought to be extinct until it was rediscovered in the Syrian desert near Palmyra in 2002. Habitat disturbance and hunting are the main drivers behind the bird's decline in its Middle Eastern habitat.

This glossy black ibis ranges in size from 70 to 80 cm (28 to 31 inches) glossy black ibis, has an unfeathered red face and head, and a long, curved red bill. It breeds colonially on coastal or mountain cliff ledges, where it typically lays two to three eggs in a stick nest, and feeds on lizards, insects, and other small animals.

According to a Turkish legend, the northern bald ibis was one of the first birds that Noah released from the ark, as a symbol of fertility.

Gastric brooding frogs went extinct thirty years ago - but today, scientists announced that they have taken a massive step forward in bringing this extinct creature back to life. A team of Australian scientists succeeded in cloning one of these frogs and taking it to the stage of an embryo, and they have now announced that they plan to go all the way and resurrect the gastric brooding frog using cloning technology.
