Adapisoriculidae is an extinct family of non-placental eutherian mammals 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.
Deccanolestes and Sahnitherium from the Late Cretaceous of India may be Cretaceous members of Adapisoriculidae.
