Eulipotyphla

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.

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

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.[10] These two branches are estimated to have split ~72-74 million years (Ma) ago.[10][1][2] The Nesophontidae and Solenodontidae are thought to have separated roughly 57 Ma ago.[10] 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.[11]

gollark: Did that one work correctly? Oh, right, real autobotrobot.
