Hegetotheriidae
Taxonomy
Hegetotheriidae was named by Ameghino (1894). It was considered monophyletic by Croft and Anaya (2006).
It was corrected as Hegetotheridae by Sinclair (1908); it was reranked as the unranked clade Hegetotheriidae by Seoane et al. (2023).
It was assigned to Tipotheria by Ameghino (1897); to Hegetotheroidea by Carroll (1988); to Typotherioidea by Reguero and Prevosti (2010); to Notoungulata by Simpson and Minoprio (1949), Simpson et al. (1962), Croft and Anaya (2006), Kramarz et al. (2010) and Vera and Ercoli (2018); and to Typotheria by Ameghino (1894), Sinclair (1908), Simpson (1934), Billet (2011) and Seoane et al. (2023).
