Fig. 5

a PC1 versus PC2 of tooth outline (85.61% of the total variation). b PC1 versus PC2 of crown cross-section (83.95% of the total variation). Deformation grids represent morphologies at the positive and negative extremes of PC1 in each plot. Numbers indicate: 1, Abydosaurus; 2, Amygdalodon; 3, Bellusaurus; 4, Bonitasaura; 5, Camarasaurus; 6 and 7, Diplodocus; 8, Kem Kem Titanosaur; 9, Mamenchisaurus; 10, MML PV 1030; 11, Nemegtosaurus; 12, Rapetosaurus; 13, Shunosaurus. Letters indicate: Le1, Lufengosaurus embryonic tooth stage 1; Le2, Lufengosaurus embryonic tooth stage 2; Le3, Lufengosaurus embryonic tooth stage 3, data taken from the mandible; Lj, Lufengosaurus juvenile, data taken from CVP 148-4; La, Lufengosaurus adult, data taken from CVP 148-6.
