Genera

Shuotheriidae is a small family of

mammaliaforms whose remains are found in China, England and possibly Russia. They have been proposed to be close relatives of Australosphenida (which often controversially includes monotremes), together forming the clade Yinotheria. However, some studies suggest shuotheres are closer to therians than to monotremes,[3][4][5] or that australosphenidans and therians are more closely related to each other than either are to shuotheres,[6] with a 2024 study suggesting that shuotheriids were closely related to Docodonta outside of the Mammalia crown group.[7]
