Frick, Aargau

Frick is a municipality in the district of Laufenburg in the canton of Aargau in Switzerland. A number of dinosaur fossils, including a nearly complete Plateosaurus skeleton, were discovered in clay pits in the town.

History

During the upper Triassic period, about 210 million years ago, the region around Frick was a dry lowland with flat hills and small depressions. During the rainy season, the depressions filled with water and dinosaurs congregated around the ponds. When they died, their bodies were covered by the mud in the ponds and fossilized, creating rich fossil beds in Frick. The first Plateosaurus fossils were discovered in 1961 and further excavations during the following decades have discovered numerous fossils. In 2006, the only Coelophysoidea (a small flesh-eating dinosaur species) fossil in Switzerland, was found by an amateur paleontologist in Frick.
