Number of specimens (N), most likely modular architectures recovered with EMMLi (MLi), covariance ratio (CR), within-module absolute correlations (ρ), correlation between oro-nasal and molar-palate modules (ρ abs), and mean within-module correlation (Mean ρ). (1) Oro-nasal/rostrum, (2) molar-palate, (3) orbit, (4) zygomatic-pterygoid, (5) vault, (6) basicranium, (7) naso-palatine (VII/VIII) / nasal (IX/X). All CR values were significant
