Fossil representation: QVM:2000:GFV:154 - Distel end of a humerus (upper arm bone).
bullockensis is an extinct species of the Aquila
genus, the same
genus that includes all living eagle species. Although only known by
the distel end of a humerus, the shape of this is an almost identical
match for the Aquila genus. This means that A.
bullockensis was in
all likelihood an eagle, but the real exciting discovery concerning
this bone is that at the time of its description, it probably
represents the eagle species not only in Australia, but the entire
The bone of A. bullockensis has been identified as being most similar to the modern extant (still alive) species A. audax (Wedge-tailed Eagle), A. chrysaetos (Golden Eagle) and A. fasciata (Bonnelli’s eagle). Out of this A. audax is of particular interest since A. bullockensis has been speculated to have possibly been ancestral to this species due to its earlier appearance.
