NEW YORK (AP) — Two fossilized dinosaur skeletons found on a Montana ranch in 2006 are coming up for sale in New York City.
The nearly complete skeletons are billed as the Montana Dueling Dinosaurs.
They'll be offered as a single lot at Bonhams on Nov. 19. The auction house estimates it could bring $7 million to $9 million.
Bonhams says the dinosaurs — a plant eater and a meat-eater — appear to be locked together in mortal combat.
They're being sold by the owners of the ranch where the fossils were found. It's located in the fossil-rich Hell Creek formation, where dinosaurs once roamed.
Each of the specimens is well preserved.
Paleontologists believe one may be a close relative of Tyrannosaurus rex. The other may be a new species similar to a Triceratops.
