Diagnosis

Reference	Diagnosis
P. Ellenberger 1972 (Pseudotetrasauropus dulcis)	Ce petit pied se remarque par un doigt l un peu écourté et plaqué contre le IIème doigt. Ces doigts II, III, IV paraissent déportés vers l'extérieur du pied où l'amorce du Vème doigt est visible. L'avant du 1er métatarse et l'amorce des 4 autres donne une étrange sole pédieuse avec un puissant talon. - PES: Longueur du pied, 230 mm (du doigt l, 90 mm; de II,100 mm; de III, 85 mm; de IV, 55 mm; de V, 30 mm ?; projection de III en avant du bout des doigts latéraux, II-IV, 21 mm). Largeur du pied entre l'extrémité des doigts latéraux, 175 mm. Divarication totale l-IV, 69" (I-V, 80°), (I-II, 30°, II-III,11° ; III-IV, 28°, IV-V, 11°). Les coussinets de phalanges sont visibles, très obliques, mais englobés dans la sole pédieuse. L'arrière du pied a à peine frôlé le sol, mais le "talon" à l'arrière externe s'est fortement imprimé au sol ("talon haut"), Les doigts se terminent pas des ongles ou des griffes émoussées. - Il y a un bourrelet positif par élévation du sol meuble tout autour de la trace. - MANUS: Nous n'avons pas vu la trace. - PISTE: Enjambée, 1,20 m ? (Pas = 0,60 m ?), Ped. angulatio ?. Ecartement, ? mm: la démarche demanderait une plus ample étude, et surtout un dégagement supplémentaire des dalles.
