 However, a 1995 paper by Robert Carroll argued that lepospondyls were actually a monophyletic group closer to reptiles.Carroll considered them closer to reptiles than the seymouriamorphs, but not as close as the diadectomorphs.Many phylogenetic analyses since Carroll (1995) agreed with his interpretation, including Laurin & Reisz (1997), Anderson (2001), and Ruta "et al."
