Well, if you want to find one in the ground, your best bet is to head to the Hell Creek Formation, a stretch of rock that runs through Montana, Wyoming, and the Dakotas.

好吧，如果你想在地下找到一个，最好的选择是前往地狱溪地层，这是一片贯穿蒙大拿州、怀俄明州和达科他州的岩石。

The first documented T. rex discovery was made in the Hell Creek Formation in 1902. And nearly all of the T. rex excavated since then — that's around 140 of them — were also found there.

第一个有记录的霸王龙发现是 1902 年在地狱溪地层发现的。此后挖掘出的几乎所有霸王龙（大约 140 只）也是在那里发现的。
