Jürgen Rudolf Sell is a self-employed master craftsman who collected fossils since his early youth. Together with fellow amateur paleontologists, he founded the Sammlung Mainfränkische Trias at Euerdorf in 1970, which is specialized on fossils from the Triassic of the Central European Basin. That collection developed into the Terra Triassica Museum which houses more than 50,000 specimens.
