The Giant Turtle That Bears The World On Its Back

In several cultures of the world, there is the concept of a gigantic turtle that holds up the Earth. Versions of the mtyh are found in India, China and North America, the last of which is known as "Turtle Island" to some tribes as a reference to the belief that the continent was resting on the back of a gigantic turtle. The European reduction of the myth is the island-beast, a creature so large that sailors take it to be an island and land upon it. When the creature submerges, the sailors are doomed. the Bestiary name for the Island-beast is Aspidochelone or snake-turtle but in some myths such as St. Brendan's voyage, it is called a "Whale"


In some versions of the myth (as in India, there are several variations of the myth), the turtle's shell is hollow and we are living inside of it. The domed carapace is the sky. This is really another version of the Tiamat myth, and the Mesoamerican version of the "Earth-monster" (Usually a sort of crocodile) is also another version of the Tiamat story.
The original for the gigantic turtle that is the World Turtle of Indian myths is the giant fossil tortoise found in India, Colossochelys atlas, whose name actually means Giant Turtle That Holds Up The Earth(or The Sky)

Colossochelys atlas

From Wikipedia, the free encyclopedia
Colossochelys atlas, formerly known as Testudo atlas, and originally described as Geochelone atlas, is an extinct species of cryptodire turtle from the Pleistocene period, [as far back as] 2 million years ago. During the dry glacial periods [ie, after 2 million years ago-DD] it ranged from western India and Pakistan (possibly even as far west as southern and eastern Europe) to as far east as Sulawesi and Timor in Indonesia.
Other members of the family Testudinidae are generally small (7–35 centimetres (2.8–14 in) long). C. atlas is the largest known member of the family, with a shell length of about 2.1 metres (6.9 ft), an estimated total length of 2.5 to 2.7 metres (8.2 to 8.9 ft) and an approximate total height of 1.8 metres (5.9 ft). Weight estimates vary greatly: some go as high as 3 to 4 metric tonnes (= 3000 to 4000 kilograms), but a weight of around 1 metric tonne (1000 kilograms)[2 at most] is probably more realistic (Paul and Leahy, 1994). The only bigger turtles were the oceanic Archelon and Protostega from the Cretaceous period. Colossochelys atlas probably looked similar to a giant Galápagos tortoise.
Like the modern Galápagos tortoise, Colossochelys atlas's weight was supported by four elephantine feet. Since most members of the related genus Testudo are herbivores, paleontologists presume C. atlas had the same diet. When a predator threatened it, C. atlas could probably retract its limbs and head into its shell, just like its modern relatives.

Giant tortoise

From Wikipedia, the free encyclopedia
Giant tortoises are characteristic reptiles of certain tropical islands. Often reaching enormous size—they can weigh as much as 300 kg (660 lbs) and can grow to be 1.3 m (4 ft) long—they live, or lived (some species are recently extinct), in the Seychelles, the Mascarenes and the Galapagos. Today, the world's largest population inhabits Aldabra Atoll in Seychelles, where there are approximately 150,000 individuals. Although appearing similar, the tortoises represent separate branches of evolution. The Seychelles and Mascarenes tortoises derive from nearby Madagascar, while the Galapagos tortoises came from nearby Ecuador.
Prior to the arrival of Homo sapiens, giant tortoises occurred in non-island locales as well. Between 200,000 to 10,000 years ago, tortoises on the mainland of Asia,[1] in Indonesia,[1] in Madagascar,[1] in North[1] and South America,[2] and even the island of Malta[1] became extinct.
These animals belong to an ancient group of reptiles, appearing about 250 million years ago. In the Upper Cretaceous, 70 or 80 million years ago some already became gigantic. About 1 million years ago tortoises reached the Galápagos Islands. Since 100,000 years ago most of the gigantic species began to disappear. Only 250 years ago there were at least 20 species and subspecies in islands of the Indian Ocean and 14 or 15 subspecies in the Galápagos Islands.
During the 16th and 17th centuries, the Galápagos were frequented by buccaneers preying on Spanish treasure ships. Filling a ship's hold with tortoises was an easy way to stock up on food, a tradition that was continued by whalers in the centuries that followed: "'whaling skippers were almost lyrical in their praise of tortoise meat, terming it far more delicious than chicken, pork or beef'. They said the meat of the giant tortoise was 'succulent meat and the oil from their bodies as pure as butter, but best of all, the giants could hibernate in a ship’s damp for a year or more.'"[3]
Today, only one of the species of the Indian Ocean survives in the wild, the Aldabra giant tortoise (two more are claimed to exist in captive or re-released populations, but some genetic studies have cast doubt on the validity of these as separate species) and 11 subspecies in the Galápagos.
Giant tortoises are among the world's longest-living animals, with an average lifespan of 100 years or more. The Madagascar radiated tortoise Tu'i Malila was 188 at death in Tonga in 1965. Harriet (initially thought to be one of the three Galápagos tortoises brought back to England from Charles Darwin's Beagle voyage but later shown to be from an island not even visited by Darwin) was reported by the Australia Zoo to be 176 years old when she died in 2006. Also, on 23 March 2006, an Aldabra giant tortoise named Adwaita died at Alipore Zoological Gardens in Kolkata. He was brought to the zoo in the 1870s from the estate of Lord Robert Clive and is thought to have been around 255 years old when he died. Around the time of its discovery, they were caught and killed for food in such large quantities that they became virtually extinct by 1900. The giant tortoise is now under strict conservation laws and is categorised as an endangered species.

Some more reconstructions and museum mounts for Colossochelys, which is something like double the dimensions of the Galapagoes or Seychelles tortoises of our times.
It would seem that the myth originates in the arera of Sundaland and adjoining-India, where pockets of Colossochelys survived and where they were not only economically exploiteed, they are indicated to have been of a particular religious and ritual status, along with the horned turtle Meiolania in Australia, New Guinea and Islands farther to the East.

Meiolania

From Wikipedia, the free encyclopedia
Meiolania ("small roamer") is an extinct genus of cryptodire turtle from the Oligocene to Holocene, with the last relict populations at New Caledonia which survived until 2,000 years ago.
The animal was rather large, measuring 2.5 metres (8.2 ft) in length, making it the second-largest known nonmarine turtle or tortoise, surpassed only by Colossochelys atlas from Asia, which lived in the Pleistocene. It lived in Australia and New Caledonia. Remains have also been found on the island of Efate in Vanuatu, associated with settlements from the Lapita culture.[1] Meiolani turtles fed on plants. Its surviving relatives are the cryptodire turtles of South America. The Meiolania specimens which were once living on New Caledonia and Lord Howe Island were much smaller than their giant relatives from the Australian continent.
When the first fossil remains (a vertebra) were found, they were originally thought to be from a large monitor lizard, similar to, but smaller than Megalania, so the genus was named accordingly. Later, when more remains were found, it was realized that the "small roamer" was actually a turtle, and not a lizard. Synonyms include Miolania and Ceratochelys.
Anatomy

Meiolania by Heinrich Harder

Front view of Meiolania platyceps fossil
Meiolania had an unusually shaped skull that sported many knob-like and horn-like protrusions. Two large horns faced sideways, giving the skull a total width of 60 centimetres (2.0 ft), and would have prevented the animal fully withdrawing its head into its shell. The tail was protected by armored 'rings', and sported thorn-like spikes at the end.[2] The body form of Meiolania may be viewed as having converged towards those of dinosaurian ankylosaurids and xenarthran glyptodonts.

DALE DRINNON: "Galapagos" tortoises in China

A while back there was a posting to the CFZ blog on the supposition that giant tortoises were brought back during a supposed Ming Dynasty circumnavigation of the Earth. I did not know what they were talking about at the time, but I think I know better now.

The supposition that the Chinese were aware of giant tortoises is based on statures of Dragon Turtles in Bejing (Peking) and elsewhere, and Dragon Turtles are traditional auspicious Chinese legendary creatures. They do not mean the same thing as the Black Warrior Tortoise of the North, which is a constellation. Looking at the depictions of the Dragon turtles you can see that the heads are vaguely shaped like a Galapagoes tortoise (Freely interpreted to add "Dragonlike" features such as whiskers) and the long neck is similar. BUT there are Tortoises nearly as large and of much the same anatoomy at the Aldabara Islands near Madagascar, and while it is theory that the Ming Chinese made it to the Galapagoes Islands, it is on the other hand a plain fact that we know the Ming Chinese reached East Africa and Madagascar. Their distinctive china is found all over the place.

Besides that much, there used to be many other islands with giant tortoises, including some islands of Indonesia. And at one point cryptid Giant Tortoises could well have co-existed with humans in India and China-old Greek records imply that much. So there are any number of alternative candidates that would be more likely than the Galapagoes giant tortoises, with a favoritism on Aldabara ones (But not discounting the possibility that the Chinese also knew of such tortoises on Madagascar or any of a number of other places. Chinese were fond of drawing Dragon Tortoises all over their maps in the spirt of "Here There Be Dragons")

Best Wishes, Dale D.

Certainly, Manouria emys, not nearly as large as Galapagos or Aldabra species, was large, and a lot closer to China.

I found a report in Bernard E.Read`s Chinese Materia Medica of turtles with shells of 10-20ft in diameter.They were said to live in Guangdong (then Kwangtung) Province.
