Bonatitan is agenus oftitanosauriandinosaur from the Late CretaceousAllen Formation ofArgentina. It was named in 2004.[1][2]
Thetype species isBonatitan reigi, first described by Martinelli and Forasiepi in 2004. Thespecific epithet honoursOsvaldo Reig. The holotype, MACN-PV RN 821, originally included a braincase and caudal vertebrae as well as limb elements. However, Salgado et al. (2014) emended the holotype to include the braincase only, and treated other elements catalogued under MACN-PV RN 821 as belonging to separate individual based on size and relative proportions.[3] The genus and species names honor the famous Argentine paleontologistsJosé Fernando Bonaparte andOsvaldo Reig.
