Adapisoriculidae is an extinct
family of non-placental
eutherianmammals present during the
Paleogene and possibly the
Late Cretaceous. They were once thought to be members of the order
Erinaceomorpha,[7]
closely related to the
hedgehog family (
Erinaceidae), because of their similar dentition, or to be basal
Euarchontans.[8] They were also thought to be
marsupials at one point. Most recent studies show them to be non-placental eutherians, however.[9]
They were small mammals of about 15 cm long, with a tail of equal length. They were probably nocturnal, eating insects and fruits.
