Fig. 3 in Late Miocene capybaras from Argentina: Skull anatomy, taxonomy, evolution, and biochronology

Fig. 3. Late Miocene capybara Cardiatherium paranense (Ameghino, 1883a), MLP 87-XI-1-3a, from Paraná River cliffs, Huayquerian SALMA, in ventral (A, B) and left lateral (C, anterior to left) views. A. Skull measurements. B. Skull landmarks: 1, posterior limit of anterior root of the zygomatic arch; 2, lateralmost point of prism I of P4, measured on the alveolar rim; 3, anteriormost point of scar marking the origin of the masseter superficialis muscle; 4, anterior limit of anterior root of the zygomatic arch; 5, midpoint of posterior margin of incisive foramen; 6, midpoint between both P4s at the level of prism I on the maxillary suture. C. Skull landmarks: 1, posterior end of incisive foramen; 2, anterior limit of anterior root of the zygomatic arch; 3, posterior limit of anterior root of the zygomatic arch; 4, point between M1 and M2 on the alveolar plane; 5, point between P4 and M1 on the alveolar plane; 6, point in front of P4 on the alveolar plane; α, angle formed by the anterior root of the zygomatic arch and the alveolar margin of the cheek teeth in lateral view.
