Hans-Jakob Siber, a mineral and fossil dealer, started in 1977 to exhibit temporarily a fossilized giant turtle from four and a half meters in length at his annual special show in Aathal, and was featuring the eight-meter-long skeleton of an Edmontosaurus four years later.
[2] The former building of the Baumwollspinnerei Streiff & Cie weaving mill in Aathal was built in 1903 and houses the museum on about 4,500 square metres (48,000 sq ft), including the outside park on the surrounding property.
[2] The focus is on the museum's own excavations and original dinosaur bones, 19 special exhibitions and subsequently integrated new finds.
[1] Beginning in the early 1990s, Hans-Jakob Siber and his team perform excavations on the Howe Ranch in the upper Jurassic Morrison Formation, and since 2010 in the Dana-Quarry, Ten Sleep, Big Horn Basin, Wyoming, USA.
