Phylogenetic relationships of Halszkaraptor and rostral coverings in maniraptorans. Strict consensus topology (A) recovered from the phylogenetic analysis of Coelurosauria. Clade diets follow Zanno and Makovicky¹⁵ (red = inferred carnivory; green = inferred herbivory). Tree length = 3306; Consistency index = 0.329; Retention index = 0.762. Silhouettes by the author. Dentaries of (A) Deinonychus, (B) Dromaeosaurus, (C) Halszkaraptor after Cau et al.³², (D) Velociraptor, (E) “Bambiraptor,” (F) Tyrannosaurus, and (G) Struthiomimus in lateral view. Arrows point to downturned ‘chins’ at the dentary symphysis. dr, lateral dentary ridge scale bar = 20 mm (B–F).
