The skeletons of two dinosaurs locked together in a fight found in the Hell Creek formation in Montana will be auctioned in November by Bonhams in New York to the dismay of many paleontologists who wished the fossils would go to a museum for further investigation.
The skeletons, which are believed to have been from the Cretaceous era, may be of two undiscovered kinds of dinosaurs. One is a Nanotyrannus lancensis, a type of pygmy T. rex, and the other a Chasmosaurine ceratopsian, a close relative to the Triceratops.
