The last of the dodos left this planet somewhere in the mid to late 17th century, brought to extinction by early European explorers and invasive species of animals introduced to its native island of Mauritius in the Indian Ocean. 
 
 Extinct but not forgotten. 
 
 The Oxford University Museum of Natural History in the U.K. houses the last remains of a dodo in the world. It's one of the museum's most precious treasures because most dodo remains today are skeletons reconstructed from bones found on Mauritius. 
 
 The "Oxford dodo," on the other hand, includes the mummified bird's skull and foot and even skin and soft tissue, making it the only specimen that retains any viable DNA. It's invaluable to research, says the university's Prof. Paul Smith. 
 
 Now, using 21st-century forensic scanning technology, Smith and other U.K. researchers have uncovered new evidence that shows the world-famous Oxford dodo had a violent death. 
 
 "We noticed these serious metallic high-density particles embedded inside the specimen," researcher Mark Williams, of the University of Warwick's Warwick Manufacturing Group (WMG), told CBC News.

 Williams is the first to scan the remains of the dodo using a high-resolution CT scan and software that created a 3D replica of the dodo's skull. 
 
 This technology allowed the researchers to see inside the specimen for the first time without actually damaging the centuries-old remains. 
 
 "When we were first asked to scan the dodo, we were hoping to study its anatomy and shed some new light on how it existed," Williams said. "In our wildest dreams we never expected to find what we did." 
 
 What they found was that the metallic particles were ammunition. 
 
 'Brutal way to go' 
 
 Williams said his team looked back at the data "and realized the pattern of these lead shots is in the back of the dodo's head. So clearly, when you look at it, he was shot in the back of the head with a shotgun." 
 
 He called it a "pretty brutal way to go." 
 
 "These birds were hunted to extinction. Their habitat was destroyed. When you look at the specimen like this one and see between 20 and 30 lead pellets embedded right in the skull, you are looking at a snapshot of its violent death," he said.

 Researchers had always assumed the nearly 400-year-old specimen had died of natural causes, its remains then transferred to the U.K. museum as an exhibit. Now they say they have proof the Oxford dodo was hunted down and killed. 
 
 Smith said it was a "really great surprise." 
 
 "The specimen that we thought we knew so well had lots ... of lead pellets embedded with the skin, embedded within the bone." 
 
 "Having small lead pellets to shoot game fowl only started at almost the same time as the bird became extinct," Williams said. "We could be looking at the first examples of lead shots ever used to hunt game birds." 
 
 Williams said the forensic work isn't done. He's hoping to do a chemical analysis of the lead pellets. 
 
 "Using those analyses, we may be able to trace which particular ore field the lead came from, and therefore what country it was mined in, and potentially what country the shot was made in so that we could then determine who killed the dodo," says Smith.

 His number one suspect? "I think there's a good chance this bird was either shot in its habitat or maybe even kept captive on a ship and shot for food." 
 
 Paleontologist Kevin Seymour says the murderer could have been anyone. 
 
 "It's kind of cool to know more information about that individual [dodo], but it isn't surprising that lots of people went to Mauritius and ate these animals," says Seymour, assistant curator of the Department of Natural History at the Royal Ontario Museum in Toronto — the only museum in Canada with a dodo skeletal display. 
 
 "They were basically eaten to extinction. And that this one was shot isn't too surprising to me, that people went there and hunted them for food." 
 
 But Williams says he's dismayed by this latest discovery about the demise of the dodo, a flightless bird labelled — some say unfairly — as clumsy and dull-witted. 
 
 "Shock and sadness, really," says Williams. "This animal was extinct 60 years after it was discovered. In the blink of an eye, it was gone." ||||| Dodos went extinct more than 300 years ago, but scientists are only now opening up a cold case after learning that one of the birds — the prized dodo specimen that likely inspired author Lewis Carroll to create a dodo character in the 1865 book "Alice in Wonderland" — was brutally murdered. 
 
 After recently loading the famous dodo into a micro-computed tomography (micro-CT) scanner, researchers noticed that the scans showed weird fleck marks in the flightless bird's neck and the back of its head. 
 
 A closer inspection revealed that those flecks were tiny lead pellets, meaning that someone shot the dodo from behind, killing the wildfowl, the researchers announced Friday (April 20). [In Photos: The Famous Flightless Dodo] 
 
 The murderous finding came as a complete surprise, said Paul Smith, the director of the Oxford University Museum of Natural History in England, where the dodo specimen — called the Oxford dodo — is on display. For years, curators thought that the specimen was the same bird that was brought to London in 1638, when the animal was still alive, Smith said. This famous dodo was a curiosity show, and people could pay to see and feed it.

 It was thought that the curiosity-show dodo died and the remains of its body was later acquired by John Tradescant the Elder, whose family provided the founding collection for the University of Oxford museums. But the great performing dodo was never shot (at least that we know of), which raises the question: Where did the Oxford dodo come from if it's not the same one that performed in the London curiosity show so many years ago? 
 
 "There is now a mystery regarding how the specimen came to be in Tradescant's collection," Smith told Live Science. The even greater mystery is, "Who killed the dodo?" Smith said. 
 
 Dodos (Raphus cucullatus) were native to Mauritius, an island east of Madagascar in the Indian Ocean. Europeans first took notice of the bird when Dutch explorers found the animals in 1598. But after decades of hungry sailors eating the birds, habitat loss and invasive rats, cats, dogs and pigs eating their eggs, dodos went extinct on their native island in 1662. 
 
 The Oxford dodo is the only specimen in the world that still contains skin and other soft tissues with extractable DNA. In a 2002 study published in the journal Science, researchers examined this dodo's DNA and found that the bird is, indeed, a giant flightless pigeon whose closest living relative is the Nicobar pigeon. 
 
 Researchers decided to study the Oxford dodo specimen again so they could get a better idea of how dodos fed and what they ate, Smith said. So, Oxford researchers coordinated with scientists at the University of Warwick's Warwick Manufacturing Group (WMG) in England, where the bird was micro-CT scanned.

 Curiously, the lead shot didn't penetrate the dodo's thick skull, the scans revealed. But these shots still killed the bird, the researchers said. 
 
 "This is a flightless bird, so obviously, somebody snuck up behind the poor thing and just shot it in the head," said Mark Williams, leader of the Product Evaluation Technologies and Metrology research groups at WMG, University of Warwick, who is studying the Oxford dodo. 
 
 Now that the cold case is open, the researchers plan to analyze the lead shot to see where it was mined. 
 
 "At the moment, we don't know where the bird was actually shot," Williams told Live Science. "Was it shot in the U.K.? More likely, was it shot in the Mauritius and then transferred to the U.K.? Was it shot for food on a ship? We really don't know."

 For a bird that has been extinct for more than 350 years, you probably think there is not much left to learn about the dodo. But you would be wrong, thanks to the latest research at the University of Warwick. 
 
 The specimen that the team based at WMG has been studying is a very famous dodo indeed. It belongs to the Oxford University Museum of Natural History and it is so precious it is kept under lock and key. 
 
 From a scientific point of view it is interesting because what the museum has is a mummified foot and head. It is our most complete set of remains of a single dodo left in existence and the only dodo soft tissue to be found anywhere - and soft tissue can be used for DNA analysis.

 But it is also a literary dodo. This specimen fascinated Charles Dodgson (perhaps better known as Lewis Carroll) and also illustrator John Tenniel. Carroll would write the dodo into his book Alice in Wonderland and Tenniel would add his famous illustrations of the bird. 
 
 Killed by humans 
 
 Finally, of course, this dodo is also a symbol. A symbol of the terrible impact humanity can have on our environment. These large flightless birds lived happily on Mauritius until Dutch explorers arrived in 1598. Just over 150 years later they were extinct. Killed by humans, or more accurately by the rats and cats we brought with us that ate the young and the dodo eggs. 
 
 Oh yes, it was not hungry sailors who did for the plump dodo, contrary to popular opinion. In fact, the dodo was not even that plump - that is a misconception based on observations of fat, captive specimens and poorly stuffed dead ones. 
 
 There is a great article on the BBC website discussing the treatment of the science of the dodo after they were wiped out and it makes pretty grim reading. If nothing else it explains why our best dodo specimen is just a foot and a head.

 A chance to put the Oxford dodo into the state-of-the-art scanners at WMG at Warwick University was not just an amazing opportunity, it was also a chance to right a historical scientific wrong - to treat the sad story of the demise of the dodo with a bit more respect this time around. 
 
 Higher power 
 
 Because the dodo is dead, the scanners the team was using could be cranked up to a higher power and better resolution than if they were being used on living tissue. The result is our most comprehensive look yet at this distant relative of the pigeon.

 First and most shocking discovery? We know what killed the Oxford dodo. Often assumed to be a captive specimen that probably died of ill treatment or disease rather than old age, it turns out the bird was actually shot in the back of the head and the neck. A number of lead shot pellets, typically used to hunt wildfowl during the 17th century, were found by the team. 
 
 Next, it might even be possible to tell which country produced the shot that actually killed the Oxford dodo. 
 
 The team also seems to be hinting at other discoveries yet to be announced. Perhaps finally after centuries of neglect, the dodo is getting the attention and respect it really deserves. ||||| New laser scans of the dodo, perhaps the most famous animal to have gone extinct in human history, have unexpectedly exposed portions of its anatomy unknown to science, which are revealing secrets about how the bird once lived. 
 
 The dodo was a flightless bird about 3 feet (1 meter) tall that was native to the island of Mauritius in the Indian Ocean. It went extinct by 1693, less than a century after the Dutch discovered the island in 1598, killed off by creatures such as rats and pigs, which sailors introduced to Mauritius either accidentally or intentionally. 
 
 The giant bird was actually a type of pigeon. "The skull of the dodo is so large and its beak so robust that it is easy to understand that the earliest naturalists thought it was related to vultures and other birds of prey, rather than the pigeon family," said study co-author Hanneke Meijer at the Catalan Institute of Paleontology in Spain. 
 
 Surprisingly, despite the dodo's fame, and the fact the bird was alive during recorded human history, little is known about the anatomy and biology of this animal. "The dodo's extinction happened at a time when people didn't understand the concept of extinction — science as we know it was still in its infancy,"lead study author Leon Claessens, a vertebrate paleontologist at the College of the Holy Cross in Worcester, Massachusetts, told Live Science. "This meant that nobody tried to make a collection of the bird or study it in detail." [Wipe Out! History's 7 Most Mysterious Extinctions] 
 
 To shed new light on the dodo, Claessens and his colleagues went to the Natural History Museum in Port Louis, Mauritius, to investigate the only known complete skeleton from a single dodo. All other dodo skeletons are composites of several birds.

 Amateur naturalist and barber Etienne Thirioux found the specimen the researchers analyzed near Le Pouce Mountain on Mauritius in about 1903. It was unstudied by scientists until now. 
 
 The scientists used a laser scanner to create a 3D digital model of the specimen. In addition, they scanned a second dodo skeleton Thirioux also created, a composite of two or more skeletons that was housed at the Durban Museum of Natural Science in South Africa. 
 
 "We discovered that the anatomy of the dodo we were looking at was not previously described in detail," Claessens said. "There were bones of the dodo that were just unknown to science until now." 
 
 These skeletons contained previously unknown bones of the dodo, such as its kneecaps. The complete specimen also preserved the original skeletal proportions of the dodo that composites made of several birds did not. [See Images of the Dodo Bird Skeletons and Laser Scans] 
 
 "The 3D laser surface scans we made of the fragile Thirioux dodo skeletons enabled us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before," Claessens said. "There are so many outstanding questions about the dodo bird that we can answer with this new knowledge." 
 
 For instance, by discovering new dodo knee and ankle bones, "we can learn a lot about how it moved," Claessens said. "It will make a tremendous difference in calculations of the muscle force the dodo could have generated." 
 
 The researchers also found that the dodo's breastbone, or sternum, lacked a keel, unlike the Rodrigues solitaire, a closely related extinct flightless pigeon that was known to have used its wings in combat. This suggests that dodos fought each other less than Rodrigues solitaires fight each other. 
 
 The smaller ancestors of the dodo must have flown to Mauritius no more than 8 million years ago, when geologists suggest the volcanic island was born. Animals on islands often grow to gigantic sizes when they do not face the same competition as they do on the mainland. 
 
 "The dodo must have experienced a fourfold increase in body mass compared to its ancestors, if not an eightfold increase," Claessens said. "If that happened in 8 million years or less, that's a rapid increase. It raises the question of how the dodo would have continued to evolve if it weren't for humans." 
 
 "The history of the dodo provides an important case study of the effects of human disturbance of the ecosystem, from which there is still much to learn that can inform modern conservation efforts for today's endangered animals," Claessens added. 
 
 In the future, the researchers "will investigate how the jaw muscles in the dodo's amazingly robust skull might have worked," Claessens said. "My best guess is that it was eating tremendously hard seeds, but who knows, maybe it was eating crabs." 
 
 The scientists detailed their findings today (Nov. 6) at the annual meeting of the Society of Vertebrate Paleontology in Berlin.

– Scientists used the latest forensic scanning technology to look inside the world's most famous dodo specimen in the hope of learning more about the anatomy of the bird that went extinct on Mauritius 350 years ago. "In our wildest dreams we never expected to find what we did," says University of Warwick researcher Mark Williams. They uncovered what the CBC labels a "dodo whodunit." Though scientists had assumed the dodo kept at Oxford University Museum of Natural History died of natural causes, inside its mummified skull were 20 to 30 "metallic high-density particles" that left no doubt how the male bird met its end: "He was shot in the back of the head with a shotgun," Williams says, adding "we could be looking at the first examples of lead shots ever used to hunt game birds." Now begins the search for the culprit: Museum director Paul Smith says a chemical analysis of the lead pellets will hopefully reveal "what country the shot was made in so we could then determine who killed the dodo." The Oxford specimen—the most complete dodo to be found and the only one to contain soft tissue and viable DNA—was previously thought to be from a dodo displayed in London in 1638 before its natural death, per the Telegraph. "Was it shot in the UK? More likely, was it shot in the Mauritius and then transferred to the UK? Was it shot for food on a ship?" Williams wonders, per Live Science. The dodo was later acquired by King Charles II's gardener and passed to Oxford, where it is said to have inspired Alice in Wonderland author Lewis Carroll, reports the BBC.
