The Irish giant deer is the largest deer on earth. They disappeared more than 7,000 years ago, and they can only be studied through fossils. But not long ago, someone found this behemoth in the jungle.
Lord Howe Island stick insect, native to Lord Howe Island, is nicknamed "lobster in the tree" by the locals. Since the appearance of an animal called the black rat on the island, this huge bug has slowly disappeared. But in recent years, scientists have discovered the existence of this large bug and protected it.
New Zealand's Southern Buzzard. Millions of years ago this bird flew from Australia to New Zealand, and then its wings slowly began to degenerate. The bird began to decline since humans introduced cats and dogs, until 1898, when humans declared their species extinct. But in recent years, humans have discovered the presence of this bird.
Cuban grooved shrew. In the 1970s, zoologists believed that the Cuban groove-toothed shrew was extinct. The poisonous mammal was captured in 1974 and 1975.
Bermuda Petrel. Humans who landed on the island found that the Bermuda petrel was easy to catch, and by the 1620s, the bird was declared extinct. In 1951, American ornithologists discovered 18 pairs of concentrated nesting Bermuda petrels in Castle Bay in Bermuda. Later, conservationists carried out efforts to rebuild the Bermuda petrels population on South Sarge Island, and by 2005 the total number of individuals had reached 250.
La Palma giant lizard. 2,000 years ago, as cats from humans came to the island to wipe out this reptile species group, the number of monitor lizards continued to decline until 500 years ago, when they were considered extinct. In 2007, still in the Canary Islands, the Giant Lizard of La Palma was rediscovered, only this time on the island of Grangaria, the only island where the monitor lizard has been found.
Over the past thousand years, the giant Lizard of La Palma has been getting shorter and shorter, and now it is only thirty centimeters long. In fact, not only the La Palma giant lizard, but other lizards on the Canary Islands have also undergone the process of being considered extinct and then rediscovered, such as the Hiero giant lizard that reappeared in 1974 and the La Gomera giant lizard that reappeared in 1999.
Lao rock rat. When the Lao rock rat was first discovered in April 2005, biologists who found it at Florida State University in the United States and Thailand classified it into a whole new species. But a year later, this classification was overturned as a branch of the late Miocene (about eleven million years ago) that became extinct in the Late Miocene of the Tertiary Period. Scientists discovered the rodent during an expedition in the central Laotian region near the Thai border.
Coelacanth, a veritable "living fossil". Zoologists thought that coelacanths had become completely extinct, but in recent years they have found living ones, and there are still two species. This fish is the ancestor of lungfish and limbed mammals and is more precious than giant pandas.
Scary little lizard. This lizard is large, can grow up to 50 cm long, and is notorious for its long, pointed teeth. Scientists once thought the horror lizard had been extinct since the 1990s, until December 2003, when experts from the French Museum of Natural History photographed a living animal, and the species returned to the ranks of the living species.
Prairie catfish, native to the Great Chaco region of Central and South America, first entered the field of scientists through fossils discovered in 1930. Since no one asked the locals if they knew of any wild boars, or pig-like animals, the species is thought to have gone extinct thousands of years ago. In 1971, reports from northern Argentina showed the presence of steppe catfish.
