One of many largest and most full fossils of its sort, the 67-million-year-old “Gus” hammered at $43m, effectively above its pre-sale estimate, promoting to an nameless telephone bidder.
The bidding for Gus rapidly went to its higher estimate of $30m, then slowed. Throughout deliberate pauses, the auctioneer reminded bidders of the “as soon as in a lifetime alternative” to personal this 38-ft-long specimen mounted on a metal armature in a threatening predatory pose.

Fossils have been purchased and offered for a whole lot of years, however costs are more and more out of the attain of museums, a lot to the detriment of science.”
