Fig. 5. Thin-plate Splines of humeri of dicraeosaurid dinosaurs Dicraeosaurus and Amargasaurus. A. Reference shape of humeri of Dicraeosaurus sattleri. B. Same reference shape adjusted onto the landmark positions of MB.R.2631 (Dicraeosaurus sattleri). C. Same reference shape adjusted onto the landmark positions of MB.R.4912 (Dicraeosaurus hansemanni). D. Reference shape of humerus of Amargasaurus cazaui, MACN N-15. Only landmarks are displaced, whereas outlines are left for better overview of shape; printouts from tpsSplin (Rohlf 2004a). E, F. Right humerus MB.R.4912 of D. hansemanni, photograph in comparison with shape-changes when fitted onto reference shape of D. sattleri. Photographs (E 1, F 1) and shape of anterior (E 2) and posterior (F ) faces modified by tpsSuper. Not to scale.
