Taxonomy
Remingtonocetidae was named by Kumar and Sahni (1986). It is the type family of Remingtonocetiodea. It was considered monophyletic by Uhen (2010). It was assigned to Odontoceti by Benton (1993); to Remingtonocetoidea by Mitchell (1989) and Rice (1998); to ArchaeocetiArchaeoceti
Archaeocetes, or "ancient whales", are a paraphyletic group of cetaceans that gave rise to the modern cetaceans.The archaeocetes were once thought to have evolved from the mesonychids, based on dental characteristics...
