Bayosaurus

"Bayosaurus" is the informal name given to an as yet undescribed genus of dinosaur. The name was coined by paleontologists Rodolfo Coria, Philip J. Currie, and Paulina Carabajal in 2006. "Bayosaurus" appears on several on-line lists of dinosaurs.[1][2][3] It apparently was an abelisauroid from the Turonian (Late Cretaceous) of Neuquén, Argentina, around 4 m (13 ft) long, based on bones including vertebrae, pelvic elements, and additional fragments.[4]
