The Gran Canaria giant tortoise [1] (Centrochelys vulcanica [2] ) is an extinct species of cryptodire turtle in the family Testudinidae endemic to the island of Gran Canaria, in the Canary Islands. [3]
This is one of the two described species of giant tortoises that inhabited the Canary Islands from the Miocene to the upper Pleistocene. The other species is C. burchardi , from the island of Tenerife. [4] [5]
C. vulcanica was described by López-Jurado & Mateo in 1993. It is believed that the ancestors of these two species of giant tortoises reached the Canary Islands from North Africa. [6] The majority of C. vulcanica fossils are of eggs and nests ranging in age from the Miocene until Pliocene. Bones and shells are known from the Miocene to the Upper Pleistocene. The maximum shell length is up to 61 centimeters, make it slightly smaller than C. burchardi, which had a shell length range of 65 to 94 cm. [7]
Fossilized tortoise eggs have been found in the islands of Lanzarote and Fuerteventura; however, these eggs have not yet been properly described or named. [8] The Fuerteventura fossils have been linked to C. burchardi, but this identification is uncertain, and has been challenged. [9] [10]
The Canary Islands, also known informally as the Canaries, are a Spanish autonomous community and archipelago in Macaronesia in the Atlantic Ocean. At their closest point to the African mainland, they are 100 kilometres west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and are the most populous special territory of the European Union.
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.
Lobos is a small island of the Canary Islands (Spain) located just 2 kilometres north of the island of Fuerteventura. It belongs to the municipality of La Oliva on the island of Fuerteventura. It has an area of 4.68 square kilometres (1.8 sq mi). It has been a nature reserve since 1982.
Manouria is a genus of tortoises in the family Testudinidae. The genus was erected by John Edward Gray in 1854.
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 Hesperotestudo 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 roughly co-incident with the arrival of the first humans in North America. There is apparently a site in Florida where one individual may have been killed that some suggested were evidence of butchering, although others suggested that the turtle was neither cooked nor does a ledge that was found near it date at the same time as it.
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.
The Canarian houbara is a large bird in the bustard family. It is a houbara bustard subspecies which is endemic to the eastern Canary archipelago, in Macaronesia in the North Atlantic Ocean, where it is a scarce and threatened non-migratory resident. It is the animal symbol of the island of Fuerteventura.
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.
Chelonoidis is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies.
Megalochelys is an extinct genus of tortoises that lived from the Miocene to Pleistocene. They are noted for their giant size, which is among the largest of any known testudine, with a maximum carapace length over 2 m (6.5 ft) in M. atlas. During the dry glacial periods it ranged from western India and Pakistan to as far east as Sulawesi and Timor in Indonesia, though the island specimens likely represent distinct species.
Centrochelys atlantica is an extinct species of tortoise that lived in the Pleistocene. It was first recorded in the volcanic crater on Sal, Cape Verde. It was initially identified as similar to the extant Testudo calcarata. The species is no longer present anywhere in the Cape Verde islands. It has since been described as a new species, differentiated from C. sulcata by its smaller size and lesser robusticity. It does not seem there is any evidence this species came into contact with humans. Kehlmaier et al. (2021) identified the type material of this species as belonging to a specimen of the red-footed tortoise, making C. atlantica a junior synonym of the latter species and leaving the extinct tortoise known from fossils excavated on the Sal Island in the 1930s without a scientific name.
The Tenerife giant tortoise is an extinct species of cryptodire turtle in the family Testudinidae endemic to the island of Tenerife, in the Canary Islands.
Centrochelys is a genus of tortoise. It contains one extant species and several extinct species:
Giant tortoises are any of various large land tortoises
Phrynops paranaensis is an extinct species of turtle from the Huayquerian Ituzaingó Formation of the Paraná Basin, Argentina, likely to be late Miocene in origin.
Chelonoidis alburyorum is an extinct species of giant tortoise that lived in the Lucayan Archipelago from the Late Pleistocene to around 1400 CE. The species was discovered and described by Richard Franz and Shelley E. Franz, the findings being published in 2009.
Solitudo is an extinct genus of tortoise that was found during the Pliocene and Pleistocene on the Mediterranean islands of Menorca, Malta and Sicily. The genus includes three described species, Solitudo robusta, Solitudo gymnesica and Solitudo sicula as well as a likely fourth, undescribed species from Monte Pellegrino in Sicily. Solitudo sicula, the youngest of the species, died out approximately 12.5 thousand years BP. The largest species, Solitudo gymnesica, has been estimated to have reached a carapace length of 1.1–1.3 m (3.6–4.3 ft).
Chelonoidis monensis, also known as the Mona tortoise, is an extinct species of land tortoise that lived on the island of Mona from the Late Pleistocene to around 1000 BCE. Evidence for the latter date includes cave drawings. All fossil remains have been found either in or near Liro Cave on the east side of Mona. It had a carapace length of around 50 cm.
