Sotheby’s sold a rare juvenile Ceratosaurus nasicornis fossil for $30.5 million in New York, smashing its $4 million-to-$6 million estimate and ranking as the third-most expensive dinosaur skeleton ever auctioned. The 150-million-year-old specimen, unearthed in Wyoming in 1996, contains 139 original bones and measures about 3.3 meters in length and 1.8 meters in height. It is one of only four known Ceratosaurus skeletons and the only juvenile example, according to the auction house. Sotheby’s said the unnamed buyer intends to lend the fossil to scientific institutions, a pledge aimed at easing concerns that escalating fossil prices—fueled by wealthy private collectors—are limiting researchers’ access to significant paleontological finds.
