Seen at the Snakewater dig, the Fossil Finder was a mobile ground penetrating Sonar unit used to search for buried fossils without digging. It had the appearance of a two wheeled dolly, and mounted to it was a post in which a shotgun shell was inserted. When activated, two people would stand on it to hold it down and it would fire the shotgun shell into the ground. It would then analyze the reflections of the sound waves created from the blast to produce an image of what was underground. This image was then sent to a computer system underneath a canopy. An interesting fact is that while the machine uses sound waves to detect what is under the ground, making the machine a Sonar machine, the technician refers to it as using Radar.
