Halcyornithidae or Pseudasturidae is a family of fossil birds, possibly belonging to the order Psittaciformes (parrots and relatives).[1] Members of this family lived in the Eocene, around 55-48 million years ago. Fossil remains are known from the Green River Formation in the United States and from the London Clay formation in the United Kingdom.[2][3] They were probably the sister group to the owl-like Messelasturidae.[4]
