A full skeleton of a Gorgosaurus is expected to sell for as much as $8 million at auction this month, in a first-ever offering of the dinosaur species at a public sale, according to Sotheby’s.

A close relative of the Tyrannosaurus rex, the well-preserved Gorgosaurus specimen dates to around 76 million years ago. At nearly 10-feet tall and 22-feet long, this dinosaur was slightly smaller than the T-Rex, which it predates by about 10 million years.

The skeleton was discovered in Montana in 2018, among a rare few Gorgosaurus skeletons to ever be found in the U.S.

It will be sold by Sotheby's on July 28 in New York with a preview week from July 21.

Rebooted after pandemic-era closures, the interdisciplinary art fair Masterpiece London, also featured a dinosaur attraction. Held at the Royal Hospital Chelsea (through July 6), the fair's showstopper was a skull of a triceratops dinosaur from the late Cretaceous period (circa 68 to 66 million years ago) discovered in Wyoming, in 2019.

David Aaron gallery director, Salomon Aaron, told the Art Newspaper that there is “a developing collector base, but one with a lot of crossovers with pre-existing customers—after all, collecting and curiosity go hand-in-hand.” The London-based antiquities dealer sold the triceratops skull to a "young" private collector for an undisclosed sum.
