Rare T. rex skeleton up for auction in Switzerland, expected to fetch millions

A composite T. rex skeleton named "Trinity" made up of 293 bones, including a rare and well-preserved skull, is expected to fetch between $5.6-$8.9 million at an auction in Zurich. The restored fossil, drawn from three sites in Montana and Wyoming, is made up of more than half original bone material. T. rex roamed the Earth between 65 and 67 million years ago, and this sale marks only the third time such a T. rex skeleton has gone up for auction.
