This is a list of resurrected species. A previously extinct or lost species can be "revived" or recreated through various methods such as cloning, breeding, genome editing, thawing, and seed germination in plants.
The Pyrenean ibex (Capra pyrenaica pyrenaica) is an Iberian ibex subspecies with the unfortunate moniker of the first animal to go extinct twice. Endemic to the Pyrenees and Cantabrian Mountains, this ibex was driven to extinction by the year 2000 due to competition with livestock and introduced wild ungulates and following the death of Celia, the endling of the subspecies. Several attempts were made to clone the Pyrenean ibex, and one individual was born to a domestic goat mother in 2003. However, this newborn died within minutes due to a lung defect. [1]
The Judean date palm is a cultivar of the date palm (Phoenix dactylifera) that is historically endemic to ancient Judea (modern-day Israel and Palestine). It is genetically unique, and closely related to modern Iraqi and Moroccan varieties. [2] Between 1963 and 1991, archaeologists discovered Judean date seeds in excavation sites. Through radiocarbon dating, they were determined to be between 1,900 and 2,300 years old. In 2008, researchers at the Arava Institute for Environmental Studies began to germinate the seeds. [2]
As of 2023 [update] , 7 Judean date palms have successfully germinated. In 2020, researchers began to harvest dates from these trees. Experiments to revive this cultivar are ongoing. [3]
The Montreal melon, also known as the Montreal market muskmelon, Montreal nutmeg melon, and melon de Montréal (Melon of/from Montreal) in French is a commercial cultivar of melon native to Canada. Traditionally grown around the Montreal area, hence its namesake. The fruit was known for being the largest melon in North America during its initial cultivation. [4] It disappeared entirely from family farms and cultivation in the region by the 1920s due to industrialisation in Canada and being ill-suited for agribusiness. In 1997, seeds of the melon were discovered in a seed bank in the American state of Iowa. Since then, the Montreal melon has been reintroduced to its former range by local gardeners. [5]
In September 2024, a specimen of a never-before-seen Commiphora by the name of Sheba reached maturity. In the 1980s, Sheba was found in excavations of a cave in the Judean desert as seed but was not germinated until recent times. Sheba is estimated to be over 1000 years old through radiocarbon dating, and researchers suspect that Sheba may be the tsori or Judean balsam, two plants stated to have healing properties in the Bible.

The Rastreador Brasilerio (Brazilian Tracker) is a dog breed that was bred in the 1950s to aid in hunting jaguars and wild pigs in Brazil. In the early 2000s, a group named Grupo de Apoio ao Resgate do Rastreador Brasileiro (Brazilian Tracker Rescue Support Group) dedicated to reviving the breed and having it relisted by Confederação Brasileira de Cinofilia located dogs in Brazil that had genetics of the extinct breed to recreate a purebred. [10] In 2013, the breed was de-extinct through successful preservation breeding from descendants of the final original members and was relisted by the FCI. [11]
Phoenix dactylifera, commonly known as the date palm, is a flowering-plant species in the palm family Arecaceae, cultivated for its edible sweet fruit called dates. The species is widely cultivated across northern Africa, the Middle East, the Horn of Africa, Australia, South Asia, and California. It is naturalized in many tropical and subtropical regions worldwide. P. dactylifera is the type species of genus Phoenix, which contains 12–19 species of wild date palms.
The cucumber is a widely-cultivated creeping vine plant in the family Cucurbitaceae that bears cylindrical to spherical fruits, which are used as culinary vegetables. Considered an annual plant, there are three main types of cucumber—slicing, pickling, and seedless—within which several cultivars have been created. The cucumber originates in Asia extending from India, Nepal, Bangladesh, China, and Northern Thailand, but now grows on most continents, and many different types of cucumber are grown commercially and traded on the global market. In North America, the term wild cucumber refers to plants in the genera Echinocystis and Marah, though the two are not closely related.
Ex situ conservation is the process of protecting an endangered species, variety, or breed of plant or animal outside its natural habitat. For example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, such as a zoological park or wildlife sanctuary. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality.
Collard is a group of loose-leafed cultivars of Brassica oleracea, the same species as many common vegetables including cabbage and broccoli. Part of the Acephala (kale) cultivar group, it is also classified as the variety B. oleracea var. viridis.
Commercial animal cloning is the cloning of animals for commercial purposes, including animal husbandry, medical research, competition camels and horses, pet cloning, and restoring populations of endangered and extinct animals. The practice was first demonstrated in 1996 with Dolly the sheep.
Ziziphus mauritiana, also known as Indian jujube, Indian plum, Chinese date, Chinee apple, ber and dunks is a tropical fruit tree species belonging to the family Rhamnaceae. It is often confused with the closely related Chinese jujube, but whereas Z. jujuba prefers temperate climates, Z. mauritiana is tropical to subtropical.
The Judean date palm is a date palm grown in Judea. It is not clear whether there was ever a single distinct Judean cultivar, but dates grown in the region have had distinctive reputations for thousands of years, and the date palm was anciently regarded as a symbol of the region and its fertility. Cultivation of dates in the region almost disappeared after the 14th century AD from a combination of climate change and infrastructure decay but has been revived in modern times.
The soil seed bank is the natural storage of seeds, often dormant, within the soil of most ecosystems. The study of soil seed banks started in 1859 when Charles Darwin observed the emergence of seedlings using soil samples from the bottom of a lake. The first scientific paper on the subject was published in 1882 and reported on the occurrence of seeds at different soil depths. Weed seed banks have been studied intensely in agricultural science because of their important economic impacts; other fields interested in soil seed banks include forest regeneration and restoration ecology.
The Arava Institute for Environmental Studies is an academic studies and research institute located in Kibbutz Ketura on the Israeli side of the Arava Valley. Following the understanding that "nature knows no borders", the Arava Institute's mission is to advance cross-border environmental cooperation in the face of political conflict.
Commiphora is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and South America. The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions.
There have been several seeds known at different times as the oldest viable seed.
Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America. This pinnately-leaved, non-spiny genus includes both small palms lacking an aboveground stem and large trees. The genus has a complicated taxonomic history, and has often been split into four or five genera based on differences in the male flowers. Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus. This has been supported by recent molecular phylogenies.
An endling is the last known individual of a species or subspecies. Once the endling dies, the species becomes extinct. The word was coined in correspondence in the scientific journal Nature.
Watermelon is a flowering plant species of the Cucurbitaceae family and the name of its edible fruit. A scrambling and trailing vine-like plant, it is a highly cultivated fruit worldwide, with more than 1,000 varieties.
Silene stenophylla is a species of flowering plant in the family Caryophyllaceae. Commonly called narrow-leafed campion, it is a species in the genus Silene. It grows in the Arctic tundra of far eastern Siberia and the mountains of northern Japan. Frozen samples, estimated via radiocarbon dating to be around 32,000 years old, were discovered in the same area as current living specimens, and in 2012, a team of scientists successfully regenerated a plant from the samples.

De-extinction is the process of generating an organism that either resembles or is an extinct species. There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered. Similar techniques have been applied to certain endangered species, in hopes to boost their genetic diversity. The only method of the three that would provide an animal with the same genetic identity is cloning. There are benefits and drawbacks to the process of de-extinction ranging from technological advancements to ethical issues.
The Pyrenean ibex, Aragonese and Spanish common name bucardo, Basque common name bukardo, Catalan common name herc and French common name bouquetin, was one of the four subspecies of the Iberian ibex or Iberian wild goat, a species endemic to the Pyrenees. Pyrenean ibex were most common in the Cantabrian Mountains, Southern France, and the northern Pyrenees. This species was common during the Holocene and Upper Pleistocene, during which their morphology, primarily some skulls, of the Pyrenean ibex was found to be larger than other Capra subspecies in southwestern Europe from the same time.
