and reassessment No apatosaurine skull was mentioned in literature until the 1970s, when John Stanton McIntosh and David Berman redescribed the skulls of Diplodocus and Apatosaurus in 1975. They found that though he never published his opinion, Holland was almost certainly correct, that Apatosaurus (and Brontosaurus) had a Diplodocus-like skull. According to them, many skulls long thought to pertain to Diplodocus might instead be those of Apatosaurus. They reassigned multiple skulls to Apatosaurus based on associated and closely associated vertebrae. Though they supported Holland, Apatosaurus was noted to possibly have possessed a Camarasaurus-like skull, based on a disarticulated Camarasaurus-like tooth found at the precise site where an Apatosaurus specimen was found years before. On October 20, 1979, after the publications by McIntosh and Berman, the first skull of an Apatosaurus was mounted on a skeleton in a museum, that of the Carnegie. In 1995, the American Museum of Natural History followed suit, and unveiled their remounted skeleton (now labelled Apatosaurus excelsus) with a corrected tail and a new skull cast from A. louisae. In 1998, Robert T. Bakker referred a skull and mandible of an Apatosaurine from Como Bluff to Brontosaurus excelsus (TATE 099-01), though the skull is still undescribed. In 2011, the first specimen of Apatosaurus where a skull was found articulated with its cervical vertebrae was described. This specimen, CMC VP 7180, was found to differ in both skull and neck features from A. louisae, and the specimen was found to have a majority of features related to those of A. ajax. Another specimen of an Apatosaurine now referred to Brontosaurus was discovered in 1993 by the Tate Geological Museum, also from the Morrison Formation of central Wyoming. The specimen consisted of a partial postcranial skeleton, including a complete manus and many vertebrae, and described by James Filla and Pat Redman a year later. Filla and Redman named the specimen Apatosaurus yahnahpin ("yahnahpin-wearing deceptive lizard"), but Robert T. Bakker gave it the genus name Eobrontosaurus in 1998. Bakker believed that Eobrontosaurus was the direct predecessor to Brontosaurus, although later Tschopp et al.'s phylogenetic analysis placed B. yahnahpin as the basalmost species of Brontosaurus. In 2008, a nearly complete postcranial skeleton of an Apatosaurine was collected in Utah by crews working for Brigham Young University (BYU 1252-18531) where some of the remains are currently on display. The skeleton is undescribed, but many of the features of the skeleton are
