Table 2 Organization of the four subsets of data. Table showing the species, number of traditional landmarks, number of semi-landmarks, and total number of landmarks in datasets (a) to (d). For dataset (d), two sets of data have been collected. One set has included Sinornithosaurus millenii and one set has excluded it as its published reconstruction is suspect (see Geometric Morphometrics Methods for details)
