Rougier et al. (2007) and Davis (2011) considered Boreosphenida to be a junior synonym of Tribosphenida; furthermore, Zofia Kielan-Jaworowska, one of the authors who named Boreosphenida, accepted this in her latest book "In Pursuit of Early Mammals" (Indiana University Press 2013, p. 134). Thus, there seems to be no reason to keep these articles separate. --Macrochelys (talk) 17:37, 16 November 2014 (UTC)
