Results of principle component analyses for all four datasets. PCA graphs based on GM data. Deformation grids for positive and negative ends of each PC are placed next to the corresponding axes. a: dataset (a), least number of landmarks; b: dataset (b), intermediate number of landmarks; c: dataset (c), largest number of landmarks; d: dataset (d), reconstruction dataset with Sinornithosaurus millenii excluded. Abbreviations: Velociraptor a, specimen AMNH FR 6516; Velociraptor b, specimen IGM 100/25
