Brontomerus
''Brontomerus'' (from Greek ''bronte'' meaning "thunder", and ''merós'' meaning "thigh") is a possibly dubious genus of camarasauromorph sauropod which lived during the early Cretaceous (Aptian or Albian age, approximately 110 million years ago). It was named in 2011 and the type species is ''Brontomerus mcintoshi''. It is probably a fairly basal camarasauromorph, though the taxon is difficult to resolve due to incompleteness of the material. It is most remarkable for its unusual hipbones, which would have supported the largest thigh muscles, proportionally, of any known sauropod.〔 The specific name is in honor of physicist and North American sauropod guru John "Jack" Stanton McIntosh.〔〔
==Discovery==
Fossils of ''Brontomerus'' were recovered from a quarry at the top of the Ruby Ranch Member of the Cedar Mountain Formation in eastern Utah, USA. The specimens were originally collected in 1994 and 1995 by a team of researchers from the Sam Noble museum of Norman, Oklahoma. It was named and described by Michael P. Taylor, Mathew J. Wedel and Richard L. Cifelli, an international team from the University College London, Western University of Health Sciences and the Sam Noble Oklahoma Museum of Natural History. The fossils were recovered from a locality known as the Hotel Mesa Quarry in easternmost Grand County, Utah. The site had been previously known to private collectors, who had already removed a considerable number of fossils, some of which may have been scientifically valuable. Exposed bones that remained were in various states of disrepair: some had even been broken and their pieces used to hold down a plastic tarpaulin.〔 Due in part to this "pillaging" of the fossil site, the team was unable to recover more complete specimens.〔
