       As a genus Sinoconodon represents one of the most primitive mammaliaforms currently known to science.‭ ‬There were once four species of Sinoconodon named,‭ ‬but it was eventually realised that all of these fossils represented individuals of the same species but at different growth stages.‭ ‬Only the type species,‭ ‬S.‭ ‬rigneyi today remains valid.
