(AP)—Two fossilized dinosaur skeletons found on a Montana ranch in 2006 are going on the auction block in New York City. They're expected to fetch between $7 million and $9 million.
The nearly complete skeletons are billed as the "Montana Dueling Dinosaurs." The sellers say the dinosaurs—one a plant eater, the other a meat eater—appear to be locked in mortal combat.
They're being sold as one lot at Bonhams auction house on Tuesday.
The skeletons were discovered by a fossil hunter on a neighbor's ranch in an area where dinosaurs once roamed.
The sellers believe one may be a close relative of Tyrannosaurus rex. The other may be a new species similar to Triceratops.
They hope a philanthropist buys them and donates them to a public institution.
