Kids aren’t the only people who love dinosaurs.

A pair of fighting dinosaur skeletons — an allosaurus and a stegosaurus — sold at auction this week for $2.75 million.

The auction, held in Texas, included meteorites, minerals and other fossils, but the dinosaurs were clearly the stars of the show. A 19-foot-long triceratops sold for more than $650,000 to a private collector. (Just think of having a triceratops in your family room!)

The fighting dinos were sold as a pair because they had been together for millions of years. They were found in Wyoming. The jaws of the allosaurus were wrapped around the leg of the stegosaurus. The pair were bought by a museum outside the United States, according to Heritage Auctions, which held the sale.

It’s not unusual for museums to spend huge amounts of money to buy rare fossils. Sue, a Tyrannosaurus rex skeleton found in 1990, was sold at auction in 1997 for $8.36 million to Chicago’s Field Museum of Natural History.
