Diagnosis
ReferenceDiagnosis
G. Gand et al. 2018grandes traces de pieds tridactyles dont la longueur est au moins égale à 24 cm. Elles sont, un peu plus longues (L) que larges (W) avec, pour l’échantillon PAGFX de référence: n = 48; m L = 30,56 cm ; vm–vM = 25–36 cm; L/W: n = 46; m = 1,06; b1–b2 = 1,03–1,1; e-t = 0, 1102; k% = 10. Les orteils II, III, IV montrent des coussinets peu marqués et indistincts dans la partie proximale de la trace où ils sont rassemblés en un talon. On note l’existence d’une symétrie presque bilatérale passant par l’axe du doigt III. L’angle II-IV = T est grand avec les caractéris- tiques suivantes pour PAGFX: n = 36; m = 73, b1–b2 = 69–76°; vm–vM = 52–87°, e-t = 10, 43; k% = 14; L’orteil III se projette plus distalement que ses voisins mais faiblement avec L-D/D: n = 45; m = 1,72; b1–b2 = 1,60–1,84; e-t = 0, 4006; k% = 23.
L’angle du pas des pistes est compris entre 140 et 179°.
