The Tenerife giant tortoise [1] (Centrochelys burchardi [2] ) is an extinct species of cryptodire turtle in the family Testudinidae endemic to the island of Tenerife, in the Canary Islands. [3] [4]

It was a large tortoise, similar to those currently found in some oceanic islands like the Galapagos Islands in the Pacific Ocean and Aldabra and the Seychelles in the Indian Ocean. [4]

The earliest remains of C. burchardi found on Tenerife date from the Miocene epoch. This tortoise is thought to have inhabited the island until the Upper Pleistocene, when volcanic activity at that time exterminated them long before humans arrived during the Holocene. [5] Most fossils are of bones and shells, as well as a nest of fossilized eggs found in volcanic soil in the south of Tenerife, in the present municipality of Adeje. This species of giant tortoise was described in 1926 by Ernst Ahl, the first time a giant tortoise endemic to the Canary Islands described. [1]

Another extinct tortoise species, C. vulcanica , is known from the island of Gran Canaria. C. burchardi had a larger shell, with a length of approximately 65 to 94 cm, while C. vulcanica shell had a 61 cm. [5] It is believed that the ancestors of these tortoises could reach the eastern islands of the Canary Islands from the African continent and progressively moved to westward through that archipelago as their size also increased and its appearance evolved to adapt to the conditions of the archipelago. [5]

Fossilized tortoise eggs have been found in the islands of Lanzarote and Fuerteventura; however, these eggs have not yet been properly described or named. [3] The species of Fuerteventura has been linked to C. burchardi, but this identification is uncertain, and has been challenged. [6] [7]

<span class="mw-page-title-main">Tortoise</span> Family of turtles

Tortoises are reptiles of the family Testudinidae of the order Testudines. Like other turtles, tortoises have a shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodira, they retract their necks and heads directly backward into the shell to protect them.

Lanzarote is a Spanish island, the easternmost of the Canary Islands in the Atlantic Ocean. It is located approximately 125 kilometres off the north coast of Africa and 1,000 kilometres from the Iberian Peninsula. Covering 845.94 square kilometres, Lanzarote is the fourth-largest of the islands in the archipelago. With 152,289 inhabitants at the start of 2019, it is the third most populous Canary Island, after Tenerife and Gran Canaria. Located in the centre-west of the island is Timanfaya National Park, one of its main attractions. The island was declared a biosphere reserve by UNESCO in 1993. The island's capital is Arrecife, which lies on the eastern coastline. It is the smaller main island of the Province of Las Palmas.

The Aldabra giant tortoise is a species of tortoise in the family Testudinidae. The species is endemic to the Seychelles, with the nominate subspecies, A. g. gigantea native to Aldabra atoll. It is one of the largest tortoises in the world. Historically, giant tortoises were found on many of the western Indian Ocean islands, as well as Madagascar, and the fossil record indicates giant tortoises once occurred on every continent and many islands with the exception of Australia and Antarctica.

<span class="mw-page-title-main">Tenerife giant rat</span> Extinct species of rodent

The Tenerife giant rat is an extinct species of rodent endemic to the island of Tenerife, the largest of the Canary Islands, Spain. Many remains have been found during archeological digs. Most remains are from the Pleistocene. Radiocarbon dating has placed some of the finds in the late Pleistocene.

<i>Canariomys</i> Extinct genus of rodents

Canariomys is an extinct genus of rodents that once existed on the islands of Tenerife and Gran Canaria, part of the Canary Islands, Spain. These giant rats could reach a weight of about 1 kg (2.2 lb). They were herbivores; their diet was based on plant materials, probably soft vegetables such as roots, ferns, and berries, but not grass. C. tamarani were considered herbivores, eating everything plant-like except grass with good digging skills. While C. bravoi were considered as a rat character, because of its large size, with an omnivorous diet with good climbing skills. They were one of two groups of rodents native to the archipelago, alongside the lava mouse, which was native to Fuerteventura and Lanzarote.

The Galápagos tortoise or Galápagos giant tortoise is a species of very large tortoise in the genus Chelonoidis. The species comprises 15 subspecies. It is the largest living species of tortoise, with some modern Galápagos tortoises weighing up to 417 kg (919 lb). They are also the largest extant terrestrial ectotherms.

<i>Hesperotestudo</i> Genus of turtle

Hesperotestudo is an extinct genus of tortoise native to North and Central America from the Early Miocene to the Late Pleistocene. Species of Hesperotesudo varied widely in size, with a large undescribed specimen from the Late Pleistocene of El Salvador reaching 150 cm (4.9 ft) in carapace length, larger than that of extant giant tortoises. Historically considered a subgenus of Geochelone, it is now considered to be distantly related to that genus. Its relationships with other tortoises are uncertain. The exposed areas of the bodies of Hesperotesudo species were extensively covered with large dermal ossicles, which in life were covered in keratin. It has been suggested that species of Hesperotestudo were relatively tolerant of cold weather. Hesperotestudo became extinct at the end of the Pleistocene and beginning of the Holocene co-incident with the arrival of the first humans in North America, and sites have been found where Hesperotestudo were butchered.

Tourism is an essential part of the economy of the Canary Islands, a Spanish archipelago located in the Atlantic Ocean, 100 kilometres west of Morocco. Seven main islands and six islets make up the Canary Islands. They had more than 9 million foreign incoming tourists in 2007. Tourists seeking sunshine and beaches first began to visit the Canaries in large numbers in the 1960s. The Canary Islands are a leading European tourist destination with very attractive natural and cultural resources.

Gallotia goliath is an extinct giant lizard species from the island of Tenerife of the Canary Islands, Spain. This reptile lived before the arrival of humans and is believed to have grown to at least 0.9 metres (3.0 ft) long. It was described by the German herpetologist Robert Mertens. Fossils of this lizard have been found in volcanic caves, where they often appear with those of other animals, like the Tenerife giant rat.

The geology of the Canary Islands is dominated by volcanic rock. The Canary Islands and some seamounts to the north-east form the Canary Volcanic Province whose volcanic history started about 70 million years ago. The Canary Islands region is still volcanically active. The most recent volcanic eruption on land occurred in 2021 and the most recent underwater eruption was in 2011-12.
