In 1987 Jerry MacDonald discovered a wide variety of beautifully preserved fossil footprints in the Robledos Mountains of New Mexico. Rumors were heard about "out of place" fossils but the site remained top secret. Finally a tantalizing article appeared in the Smithonian Magazine, July, 1992. The article acknowledged "what paleontologists like to call, 'problematica.'" It described what appeared to be large mammal and bird tracks that, "evolved long after the Permian period, yet these tracks are clearly Permian." With a little detective work and some luck we located the area and even more obvious "problematica."
