Description

The type species is Bonatitan reigi, first described by Martinelli and Forasiepi in 2004. The specific epithet honours Osvaldo 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.[1] The genus and species names honor the famous Argentine paleontologists José Fernando Bonaparte and Osvaldo Reig.

gollark: Yes, I'm aware, that's why I'm reencoding it.
