NEW YORK CITY -- Two dinosaur skeletons will go on the auction block in New York City on Tuesday, but the sale of such a rare find is dividing the scientific community.
At the center of the debate are two fossilized skeletons, known as "The Dueling Dinosaurs." The nearly complete remains are of a large plant eater and a smaller meat eater. They were found locked together, leading some to believe they perished after a violent death match 68 million years ago.
One dinosaur's skull is actually cracked -- a blow that has led Clayton Phipps to believe that's what probably killed it.
Phipps discovered the relics on a private ranch in Montana in 2006. An amateur dinosaur hunter, Phipps says the find was so rare, he was met with skepticism from the scientific community. He said, "I contacted several of the major U.S. museums personally, and I think (they thought), 'Yeah right, this guy doesn't have what he says he has'."
