[1] The specific name is in honor of physicist and North American sauropod expert John Stanton McIntosh.

Other recovered fossils include a crushed presacral centrum, several caudal vertebrae, a right-side dorsal rib, a large scapula, and two partial sternal plates.

[3] Its assignment to a new species is based on several noteworthy autapomorphies, including an oddly-shaped hipbone which would have permitted the attachment of unusually massive leg muscles.

[1] Fossils of Brontomerus were recovered from a quarry at the top of the Ruby Ranch Member of the Cedar Mountain Formation in eastern Utah, United States.

[6] Based on phylogenetic analysis using a 50% majority rule tree, Brontomerus was initially placed as a basal somphospondyl within Titanosauriformes, in a trichotomy with Euhelopus and the Titanosauria.

[7] In 2013, Mannion et al. found Brontomerus to be securely classified as a basal somphospondyl, but were not able to resolve its affinities more precisely.

[2] Dr. Matthew Wedel, assistant professor of anatomy at the Western University of Health Sciences in Pomona, California, has stated that since it has been commonly been assumed that sauropods tend to prefer drier, upload areas, perhaps Brontomerus may have used its powerful leg muscles for traversing rough, hilly terrain.

The authors acknowledge that while the unusual qualities of the hipbone probably have some functional significance, it is difficult to assess without further information about the pelvis, femora and proximal caudals.
