Figure 27 in Osteology and ecology of Megantereon cultridens SE311 (Mammalia; Felidae; Machairodontinae), a sabrecat from the Late Pliocene - Early Pleistocene of Senéze, France
Figure 27. The skeleton of Megantereon cultridens SE311 as it stood when still mounted in the exhibitions at the Natural History Museum in Basel. As reconstructed, the skeleton has seven cervical, 12 thoracal and seven lumbar vertebrae, and is thus missing a posterior thoracal vertebra. The vertebra here placed as lumbar 3 is, however, the rather poorly preserved thoracic 11, and the actual missing vertebra is lumbar 1.

Figure 29 in Osteology and ecology of Megantereon cultridens SE311 (Mammalia; Felidae; Machairodontinae), a sabrecat from the Late Pliocene - Early Pleistocene of Senéze, France
Figure 29. Cast of skull and lower jaw of Megantereon cultridens SE311 showing the lower jaw in normal posture at full occlusion (A), at the gape angle (~61°) at which the upper and lower canines clear each other (B), and at maximum inferred gape (~105°). A gape angle of 61° is broadly comparable with maximum gape in extant carnivores (Emerson & Radinsky, 1980; Akersten, 1985; Christiansen & Adolfssen, 2005). At maximal gape angle, the clearance between the upper and lower canines would be around 10 cm, comparable with the values in extant big cats (Christiansen & Adolfssen, 2005).
