A large-scale excavation campaign commenced in the summer of 2012, with the goal to excavate "Europasaurus" bones not only from lose blocks but directly from the rock layer. Access to the bone-bearing layer required the removal of some 600 tons of rock using excavators and wheel loaders, and the constant pumping out of water from the base of the quarry. Excavations continued in spring and summer 2013. The campaign resulted in the discovery of new fish, turtle, and crocodile remains, as well as valuable information of the bone-bearing layer; additional "Europasaurus" bones, however, could not be located. By 2014, around 1300 vertebrate bones had been prepared from bed 83, the majority of which stemming from "Europasaurus"; an estimated 3000 additional bones await preparation. A minimum number of 20 individuals was identified based on jaw bones.
