One hundred and twenty million years ago, when a Cretaceous sea covered what is now South Australia, an ichthyosaur had a really bad day.

一亿两千万年前，白垩纪的海洋覆盖着现在的澳大利亚南部，一条鱼龙（注：一种类似鱼和海豚的大型海栖爬行动物）经历了十分糟糕的一天。

The researchers found that the wounds on the Australian ichthyosaur had partially healed; remodeled bone around the bite marks confirmed that the animal lived for a long time after the trauma.

研究者发现这条澳洲鱼龙的伤口已经部分愈合了；咬痕周围的骨骼重构证实它在这次创伤之后又存活了很长时间。
