Some 80 years after A. rex, a second species Anatalavis oxfordi was described by Olson, based on fossils found in the earliest Eocene (Ypresian age, about 55 mya) London Clay Bed A at Walton-on-the-Naze, England, and named in honor of the collector Andrew Oxford of Great Mongeham, Kent, who donated the fossil for scientific research. This species is known from a partial skeleton, one of the best-preserved London Clay fossils at the time it was found, but in a delicate state of preservation and much broken. Even so, the close similarity of its humerus to the remains of the A. rex was noted. Olson at that time also erected the subfamily Anatalavinae for the genus. Jiří Mlíkovský in 2002 disagreed with uniting A. oxfordi with the considerably older A. rex and pointed out that the
