When a giant tortoise named Lonesome George died, his kind, the Pinta
Island tortoises of the Galapagos, suffered the same fate as the
unfortunate dodo bird: Both bird and tortoise were wiped off their
island homes and into extinction.
But Lonesome George will be better preserved than any of the lone-gone dodos, which disappeared more than three centuries ago from Mauritius in the Indian Ocean.
More than a year after his death, Lonesome George's remains are now in
Woodland Park, N.J., where a team of taxidermists is working to preserve
his physical presence by making a mount from his skin, shell and other
external parts. After Lonesome George's mount is complete, New York's
American Museum of Natural History expects to display it before sending
it back to the tortoise's native Galapagos. [See Photos of Lonesome George Being Preserved]
"I think there is a very powerful moment when you come face-to-face
with a piece of taxidermy of an extinct species," said George Dante, a
taxidermist and president of Wildlife Preservations, the company working
on the Lonesome George mount. "It's not like flipping through a book or
clicking online."
The missing dodo
Dante has restored specimens of other extinct species, including the passenger pigeon, the thylacine
(a large, carnivorous marsupial that lived in Tasmania), the Carolina
parakeet and others. But neither Dante nor any other taxidermist has
ever worked on an original dodo specimen.
Like giant tortoises living on the Galapagos Islands, the dodos (Raphus cucullatus)
that lived on Mauritius provided food for sailors. Seafarers'
introduction of invasive species, such as goats and rats, also
contributed to these formerly isolated animals' doom. [6 Extinct Species That Could Be Brought Back to Life]
Dodos appear to have gone extinct in the late 17th century. The only
taxidermic specimens are artists' recreations, made of materials such as
pigeon or goose feathers, said Dante, who worked on a scientifically
accurate model of the extinct bird for a museum in Singapore.

Productions to recreate the dodo, commissioned in 2005 for a museum in

Research for the model revealed that reliable descriptions and depictions of the dodo are scant, according to a description of the project published in 2007 in the taxidermy-focused Breakthrough magazine.
"One of the big reasons there are so few remains of dodos is because
people loved to eat them," saidChris Raxworthy, associate curator of
herpetology at the American Museum of Natural History. "No one thought
to set them aside for future generations."
Preserving a modern extinction
Meanwhile, Lonesome George's
well-documented story took place in recent times. He was first spotted
alone on La Pinta Island in 1971. Attempts to get him to mate were
unsuccessful, and he became a conservation icon and an embodiment of
humans' impact on the natural world. When Lonesome George died in June
2012, he was estimated to be about 100 years old.
At the Wildlife Preservations studio, Dante is several weeks into a
process that is likely to take six or seven months. In the end, every
visible part of the mount, except its glass eyes, will come from
Lonesome George's remains. Foam, steel and wood will replace his muscle,
skeletal structure and innards.
The pose selected for the mount will show off the tortoise's long neck.
"His head is going to be elevated about 3 feet (0.9 meters) above the ground, probably a lot higher than people imagine [a tortoise] can reach," Raxworthy said, adding that the tortoise's saddleback shell, which is raised in front, allowed the tortoise to rear his neck up higher than a domed shell would have.
Um zoológico trágico
O museu abriga outras peças de taxidermia que preservam os restos de espécies extintas, que incluem o moa gigante da Nova Zelândia, o pato Labrador, o pombo-passageiro e o tilacino, que é mais comumente conhecido como lobo da Tasmânia ou tigre-da-tasmânia.

Embora seja claro que Lonesome George foi o último de sua espécie, os cientistas ainda debatem se as tartarugas da Ilha Pinta são uma subespécie de uma única tartaruga gigante de Galápagos ou se tartarugas da Ilha Pinta são uma das muitas espécies de tartarugas gigantes de Galápagos, disse Raxworthy, que apóia a designação. eles uma espécie completa.
Mas a genética adicionou uma reviravolta à história de Lonesome George. Pesquisas revelaram a existência de tartarugas híbridas com a herança da tartaruga La Pinta em outra ilha nas Ilhas Galápagos. Através da criação cuidadosa, os conservadores poderão um dia produzir uma tartaruga que compartilhe a maior parte da herança La Pinta de Lonesome George, disse Raxworthy.
