Dingoes never reached Tasmania, and most scientists see this as the main reason for the thylacine's survival there.

野狗从未到达过塔斯马尼亚，大多数科家认为这是袋狼在那里生存的主要原因。

The thylacine appeared to occupy most types of terrain except dense rainforest, with open eucalyptus forest thought to be its prime habitat.

除了茂密的雨林， 袋狼似乎占据了大多数类型的地形，开阔的桉树林被认为是的主要栖息地。

Approximately 4,000 years ago, the thylacine was widespread throughout New Guinea and most of mainland Australia, as well as the island of Tasmania.

And while we know thylacines and Thylacoleo both existed, there are other animals in the Arnhem Land pictures that seem to straddle the line between imagination and reality.

In 1914, he was sufficiently concerned about the scarcity of the thylacine to suggest that some should be captured and placed on a small island.

1914 年，他非常担心袋狼的稀缺，建议捕获一些袋狼并将其放在一个小岛上。

The most recent, well-dated occurrence of a thylacine on the mainland is a carbon-dated fossil from Murray Cave in Western Australia, which is around 3,100 years old.

大陆上最近发现的袋狼是一个碳年代测定的化石， 来自西澳大利亚的 Murray Cave，大约有 3,100 年的历史。

However, there seems to have been little public pressure to preserve the thylacine, nor was much concern expressed by scientists at the decline of this species in the decades that followed.

然而， 保护袋狼的公众压力似乎很小，科家们也没有对这一物种在随后几十年中的衰落表示太多关注。

These include competition with wild dogs introduced by European settlers, loss of habitat along with the disappearance of prey species, and a distemper-like disease which may also have affected the thylacine.

其中包括与欧洲定居者引入的野狗的竞争、栖息地的丧失及猎物物种的消失，及可能也影响了袋狼的犬瘟热样疾病。

And this is even more impressive considering that we now also know that it's not really related to any of the predatory Australian marsupials that you might've heard of, like the Tasmanian devil or the now-extinct thylacine.

考虑到我们现在也知道与您可能听说过的任何掠食性澳大利亚有袋动物（例如塔斯马尼亚袋獾或现已灭绝的袋狼）都没有真正的关系，这一点更令人印象深刻。
