By the numbers: The rare Nanotyrannus skeleton sold for $47.3 million to an unidentified buyer at a Tuesday auction in New York City, Sotheby’s said. The dinosaur was recently confirmed to be a distant relative of Tyrannosaurus rex, rather than a juvenile T. rex. Sotheby’s had estimated the fossil would sell for $6 million to $9 million.

This summer, a T. rex fossil known as "Gus" sold for a record $50.1 million at Sotheby's.

What we don't know: The new owner of "Jodi" has, for now, chosen to remain anonymous after outbidding five other prospective buyers online and by phone during the roughly 12-minute live auction, Sotheby’s said.

Nanotyrannus had relatively longer forelimbs and larger hand claws, as well as more slender, blade-like teeth than its famous cousin. "Jodi" is one of only three such skeletons known to exist. Standing 9 feet 6 inches (2.9 meters) and stretching nearly 20 feet (6 meters), it has been on display at the auction house’s upper Manhattan headquarters since earlier this month, and is considered almost 70% complete.

The dinosaur is named after Jodi Pierson, the Montana rancher who discovered it on her land in 2019. What they're saying: Sotheby’s, in a statement, thanked the team of professional fossil hunters whose efforts to discover and excavate the specimen were the focus of the Discovery Channel documentary series "Dino Hunters" in 2020.

"Their commitment to understanding and preserving this remarkable specimen has helped bring us to this moment, a testament to the fact that we can all make major contributions to science," said Cassandra Hatton, Sotheby’s head of science and natural history. The other side: However, some scientists have opposed such private sales, saying "Jodi" and other significant fossils should be displayed in museums or other institutions so they can be studied by researchers and viewed by the public.

Scientists for decades weren't even sure whether Nanotyrannus represented a distinct type of dinosaur or merely a juvenile T. rex. But research published last year concluded that it was in fact a distinct genus of dinosaur. The Source: The Associated Press contributed to this report.
