2, The phylogenetic topology follows Prideaux G.J. (2004) Systematics and evolution of the sthenurine kangaroos. Geological
Sciences, Vol. 146. University of California Publications.
3, Placed as a sister species to the only other Zaglossus species for which we had data, the western long‐beaked echidna, Z.
Bruijini.
4, The phylogeny of Elephantidae follows Shoshani, J. & P. Tassy (2005) Advances in proboscidean taxonomy & classification,
anatomy & physiology, and ecology & behaviour. Quaternary International , 126–128, 5–20. Woolly mammoth and Sardinia
M. lamarmorae were designed as sister species as they belong to the European clade of Mammuthus.
5, Elephas antiquus and E. namadicus are sister species and regarded as synonyms in Maglio, V. J. (1973) Origin and evolution
of the Elephantidae. Transactions of the American Philosophical Society, 63, 31–144. Both species are often placed in the
genus Palaeoloxodon to which P. naumanni also belongs.
6, Columbian mammoth and Santa Rosa pygmy mammoth belong to the North American clade of Mammuthus.
7, Placed outside the clade Mammuthus+Elephas+Loxodonta as with note (4).
