If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

H. F. Osborn 1905Carnivorous Dinosaurs attaining very large size. Humerus believed to be oL large size and elongate (Brown). No evidence of bony dermal plates (Brown).
H. F. Osborn 1905 (Dynamosaurus imperiosus)Twelve to thirteen mandibular teeth.
K. Carpenter 1992Angular terminates posterior to the surangular fenestra. Surangular fenestra much larger than in Tyrannosaurus baatar. Maxilla terminates below the lacrymal.
