The new fossil findings were published in the November 13 issue of the science journal Proceedings of the Royal Society B: Biological Sciences. Tseng and his team were fossil hunting in the Himalayas in 2010 when they discovered some bones, including the buried cat skull. The researchers were able to determine its age by studying the surrounding rocks and soil. The skull indicates that the animal was about the size of a clouded leopard, which can grow up to 50 pounds. In 2017, the team returned to unearth more cat bones.

　　David Polly from Indiana University told the Associated Press that the fossil is “convincingly older than the_current_record_holder”. He added that there could be even older big cat fossils in the Tibetan plateau to uncover.

　　文章大意：本文讲述了最新考古发现——一个大型猫科动物的颅骨化石。

　　5．What does the newly unearthed skull prove?

　　A．Big cats might have their origins in Asia.

　　B．The oldest fossil is 4.4 million years old.

　　C．The snow leopard is the oldest big cat.

　　D．The skull is of big cats' direct ancestor.

　　答案：A　推理判断题。由第二段最后一句话“The fossil lends evidence to the belief that big cats existed in Asia and spread out from there.”可推知，该化石使我们相信大型猫科动物起源于亚洲，然后繁衍到其他地方。
