Description

Palaeoryctidae or Palaeoryctoidea ("old/stony digger", from Greek: ὀρύκτης, oryctes) is an extinct group of relatively non-specialized non-placental eutherian mammals that strived in North America during the late Cretaceous and took part in the first placental evolutionary radiation together with other early mammals such as the leptictids. Some sources classified the Palaeoryctidae as a superfamily.
