Allosaurus "whitei" (Pickering, 1996) was based on a skull with hyoid,
presacral column, sacrum and pelvis (AMNH 666). It was diagnosed by the
same characters Paul used to distinguish A. "atrox", so is invalid for the
same reasons. Chure rejects the validity of the name, as Pickering didn't
follow ICZN Article 7 Recommendation 7a, Article 8a or Recommendation 8A. It is therefore considered a nomen nudum in addition to being a junior synonym of A. fragilis.
