Drusilasaura

Drusilasaura is an extinct genus of possible lognkosaurian titanosaur sauropod dinosaur which lived during the late Cretaceous (Cenomanian-Turonian stage) of Santa Cruz Province of southern Patagonia, Argentina.

Drusilasaura is known from the holotype MPM-PV 2097/1 to 2097/19, a partial skeleton including four dorsal vertebrae, a sacral vertebra, six caudal vertebrae, a left scapula, dorsal rib fragments and other fragments. It was found by palaeontologist Marcelo Tejedor searching fossil mammals, in layers of the Upper Member of the Bajo Barreal Formation, on the María Aike Ranch owned by the Ortiz de Zárate family. A team from the Laboratorio de Paleontología de Vertebrados of the Universidad Nacional de la Patagonia San Juan Bosco subsequently collected the remains.
