So _Altispinax_ would properly be cited as:
_Altispinax_ Kuhn 1939
= Altispinax von Huene 1923 [nomen nudum]
    _Altispinax dunkeri_ (Dames 1884) Kuhn 1939 [type]
    = _Megalosaurus dunkeri_ Dames 1884

And _Becklespinax_ as:
_Becklespinax_ Olshevsky 1991
    _Becklespinax altispinax_ (Paul 1988) Olshevsky 1991
    = _Acrocanthosaurus altispinax_ Paul 1988
    = _Altispinax altispinax_ (Paul 1988) Rauhut 2000
