Families
Hispaniolan solenodon (Solenodon paradoxus). Solenodons are estimated to have diverged from other extant eulipotyphlans in the Late Cretaceous.[1][2]

Eulipotyphla ("truly fat and blind"[3]) is an order of mammals suggested by molecular methods of phylogenetic reconstruction, and includes the laurasiatherian members of the now-invalid polyphyletic order Lipotyphla, but not the afrotherian members (tenrecs and golden moles, now in their own order Afrosoricida). Lipotyphla in turn had been derived by removing a number of groups from Insectivora, the previously used wastebasket taxon.

Eulipotyphla comprises the hedgehogs and gymnures (family Erinaceidae, formerly also the order Erinaceomorpha), solenodons (family Solenodontidae), the desmans, moles, and shrew-like moles (family Talpidae) and true shrews (family Soricidae). True shrews, talpids and solenodons were formerly grouped in Soricomorpha; however, Soricomorpha has been found to be paraphyletic, since erinaceids are the sister group of shrews.[4][5][6]

The upper and lower basal subclades within the tree are the suborders Solenodonota and Erinaceota, respectively.[7] These two branches are estimated to have split ~72-74 million years (Ma) ago.[7][1][2] The Nesophontidae and Solenodontidae are thought to have separated roughly 57 Ma ago.[7] Split times for talpids vs. soricids plus erinaceids, and for soricids vs. erinaceids, have been estimated at around 69 Ma and 64 Ma ago, respectively.[8]
