Geology of the Mesozoic Era

Diplodocus carnegii

DiplodocusDiplodocus carnegii aka Dippy was found in the Jurassic Morrison Formation of eastern Wyoming in 1899. This was the first dinosaur skeleton acquired for Carnegie Museum's collections. This specimen was found in green shale and limestone that were deposited in an ancient lake. Recently, Brezinski and Kollar (2008) proposed that this skeleton was preserved during a period of dry climate that produced the limestone layer that directly overlies the animals bones.
