 Next week, the largest and most complete Stegosaurus skeleton ever found is going up for auction as part of Sotheby's so-called Geek Week. It's known as Apex, and it's expected to fetch somewhere between four and six million dollars U.S., which is cool for you if you're incredibly wealthy and you have an extra room that can fit a six meter long fossil. But it's not cool to scientists, many of whom are not on board with the private purchase of paleontological treasures like this one.
