It is also known as the Tasmanian Tiger or Tasmanian Wolf.

Hobart Zoo c. They found evidence of existence of the thylacine, bringing back stories, photographs and casts of footprints though they did not see an actual animal. In his report, Sharland recommended that an area of the NW be reserved for the protection of the thylacine. This photograph was taken by Sharland of thylacines in the Hobart Zoo.

Is there a fossil Thylacine? It even has a long, thick tail like a kangaroo, and is about the size of a large Labrador retriever.

What on Earth is it? It just might be a Tasmanian tiger Thylacinus cynocephalus , also known as Tasmanian wolves or thylacines. Although scientists generally believe that the species went extinct in , people still report sightings of odd animals resembling Tasmanian tigers.

As of yet, though, no conclusive proof exists. In recent history, Tasmanian tigers were restricted to the island of Tasmania, but they once lived on the Australian mainland and even Papua New Guinea as well. Tasmania had few people and no dingoes, though, so it became a last refuge to the Tasmanian tiger and its close cousin, the Tasmanian devil.

In fact, by the time white settlers first arrived in Tasmania in the s, people estimated that there were only about 5, Tasmanian tigers left at all. The settlement of Tasmania by white settlers marked the beginning of the end for the Tasmanian tigers.

They brought large quantities of livestock with them and assumed that Tasmanian tigers would be just as fearsome livestock killers as the Western wolves and coyotes with which they were familiar.

Tasmanian tigers certainly did kill some livestock , but most people believe now that the numbers were greatly exaggerated. The Tasmanian government responded to these fears by instituting a bounty system and eventually paid out more than 2, bounties.

In Australia, the settlers brought dogs with them. There were reports that a distemper-like disease was killing many Tasmanian tigers right before the wild population winked out of existence. Despite presumptions to the contrary, it turns out that they might not even have been physically able to routinely kill large livestock. The massive witch hunt that led to their demise might have been completely unnecessary. Their jaws were simply too long and skinny for that kind of diet.

Instead, they probably ate smaller prey like possums and bandicoots. Females tended to be much smaller than males and were probably easier for dogs and dingoes to kill. Even if females made it past their predators, though, they could only support four young at a time—not nearly as many as their placental mammal counterparts.

As the Tasmanian tiger population started diminishing, people realized what was happening. Zoos around the world began scooping up live specimens while they still had a chance, and there was a lucrative trade for the last few animals.

The last remaining live specimen turned out to be Benjamin , a Tasmanian tiger held in a zoo in its native Tasmania. By the time Benjamin was in the zoo, the Tasmanian government finally came to its senses and passed legislation protecting Tasmanian tigers. It came too late, though—just 59 days after the legislation was signed into law, a neglectful zookeeper locked Benjamin out of his sheltered area on a cold night, and the last Tasmanian tiger died of exposure.

The extinction of the Tasmanian tiger was a hard lesson to learn. We know we need to avoid manufacturing witch hunts against an entire species, to keep tabs on dwindling populations better, to start conservation efforts before the last living animal is identified. She also spent her time in Alaska racing sled dogs, and studying caribou and how well they are able to digest nutrients from their foods.

Now, she enjoys sampling fine craft beers in Fort Collins, Colorado, knitting, and helping to inspire people to learn more about wildlife, nature, and science in general. Biodiversity Tasmanian tiger. What happened to the Tasmanian tiger?

Based on their teeth and jaw, it is almost certain that they were meat specialists.

Anecdotal evidence suggests thylacines may have taken large prey up to 30kg, such as kangaroos and emus. But few naturalists were present to record its foraging behaviour and many accounts are derived from unreliable or biased sources. Morphological features, such as their extremely long snout and very low rates of canine tooth wear and fracture suggest they relied on small prey, though their wide gape may have allowed them to catch larger species.

Thylacines were thought to use caves as lairs, and have been associated with prey found in sub-fossil cave deposits. These ranged in size from 1 to 5kg. As prey brought back to a den may be the smaller species killed, they may not represent the full range of prey species killed by thylacines. With the advancement of new techniques, it may be possible to conclusively evaluate the diet of the thylacine.

The mechanical performance of the thylacine skull may provide clues into their mode of hunting and disclose limitations in the size of prey they could catch. These are both capable of hunting large prey relative to their own body size. If thylacines were able to take down large prey, we would expect their skulls to perform similarly under different feeding simulations. Computed tomography CT scans of each skull were digitised to create a three-dimensional model. Beams were attached to the skull to simulate the different jaw-closing muscles that act on the skull during chewing.
