Finding the Dueling Dinosaurs felt like winning the lottery to everyone involved, especially the landowners. Mary Ann and Lige Murray came to Montana in 1971, fresh out of college and chasing the cowboy dream. They worked their way up from ranch hands to owners but haven't yet paid off the land they bought 30 years ago. With the discovery of the dinosaurs came hope. "If you found an oil well on your land, would you be willing to just donate it or give it away?" asks Murray. "It is an investment we made when we bought the land. It's no different than finding minerals on your place."

Phipps and his partners initially considered an auction, but their desire to have the dinosaurs available for science has kept them off the block -- until now. After consultations with commercial appraisers, they priced the Dueling Dinosaurs at $9.8 million. "That's what people don't understand, and I don't think our country does, because it is just three or four times in the world they have found two together. And these are the biggest and most complete," says Murray. "Lige and I can certainly use the money, but (Clayton and his partners) can, too, and Chad is disabled. It's a win-win for everybody."

Despite the big price tag, the Dinosaur Cowboy contends that his requests remain simple. He's put his family's money, along with hundreds of hours of time, into the collection and preparation of the dinosaurs, and he wants to make enough to remain on his land and pay some bills.

He and his partners have watched other dinosaurs pass through the market in recent years, mostly at the drop of a gavel. Two years ago, the "Fighting Dinosaurs," a Stegosaurus and Allosaurus found near each other in a Wyoming quarry, fetched $2.75 million from an undisclosed buyer overseas. Offers have been made on the Dueling Dinosaurs by unnamed parties, but nothing has come to fruition.

Soon the blocks will be shipped to Bonhams New York City auction house, where they'll be offered in a Nov. 19 sale along with other fossils and collectibles. Bonhams expects the bones to fetch between $6 million and $9 million. Until then, the bones are gathering dust at CK Preparations, lingering in the hopes that Ronald McDonald, Mickey Mouse or an anonymous Samaritan will save the day. Morrow and Busch live in a trailer next to the facility they bought to house the dinosaurs. Larson's Nanotyrannus thesis is on hold.

Bakker says all the paleontological infighting has obscured the real –– and important –– story of these fossils, one that could change our understanding of dinosaur behavior: a duel to the death during the last days of the dinosaurs. "That comes from a sense of elitism I really dislike," he says. "I call it the priestly caste."

For his part, Phipps wants the Dueling Dinosaurs to be publicly displayed. He'd also like to have a replica donated to the local museum in Jordan. Replicas are just fine, he says, because the town museum can't afford to keep the heat on and icy air is bad for fossils. "I'm hoping someday I can take my grandchildren to go see them," Phipps says, "and tell them, 'Your ol' granddaddy found those dinosaurs.' "
