I remember a case in which what had long been considered the world record pronghorn buck was found to have been faked. They were examining it and noticed a strange crack about a half inch above the base and x-rayed it. Somebody, many years before had taken another piece of horn and had split it used it to make the horn longer. Pronghorn horns can be steamed and removed from the core and that is what they did and after removing it had fitted the split pieces in place and nailed them with small nails and covered up the cracks/seams/nails with lamp black. I remember seeing a photo of the x-ray but it was more than 20 years ago. This was done long before they kept records and nobody even knew who killed the animal since the head was just found hanging in a saloon. This is why they now x-ray all potential high scoring animals for the record books.
