Phil, I've been using GONIAT for almost 10 years now. Make sure you have a directory structure like it shows in the readme file. The new windows version is harder to figure out than the old dbase runtime version. A great program that has info on every species of described paleozoic ammonoid, I would be lost without it. There are suture figures for two species of Kazakhoceras but neither match the specimens I have exactly, and all six described species are a little younger (about 320-329my old).
