==Discovery== The holotype of Eusaurosphargis dalsassoi (BES SC 390) is a partial skeleton of a single individual found disarticulated but in close association. BES SC 390 was collected from an oil shale at Cava di Besano of the Besano Formation (Grenzbitumenzone). These lagoonal beds are equivalent to those at Monte San Giorgio, dating to the Anisian-Ladinian boundary, probably to the latest Anisian at this location, of the early Middle Triassic, about 243 million years ago. Nicole Klein and Oliver J. Sichelschmidt (2014) described disarticulated remains they referred to Eusaurosphargis sp. These remains were collected from the Dutch Winterswijk Quarry III of the Vossenveld Formation, dating to the late Anisian stage.
