TimeLine Gracile species appeared ~ 4 M ya but disappeared ~ 2 M ya, whereas robust species persisted from ~ 4–1 M ya. P. boisei. boisei and Au. Puede haber debates sobre la filogenia del australopiteco en relación con el Homo, pero hoy nadie pone en duda que el A. robustus y el A. boisei están fuera de esta línea, extinguiéndose hace 700.000 años y calculándose su aparición hace aproximadamente 2 millones de años.

It was similar to robustus, but the face and cheek teeth were even more massive, some molars being up to 2 cm across. See more.

Australopithecus, group of extinct primates closely related to modern humans and known from fossils from eastern, north-central, and southern Africa. The Shape and Position of the Zygomatic Bone in Australopithecus boisei The gradual anterior migration of the masseter muscles, as inferred from the position of the inferior margin of the zygomatic bone, is part of an effort to provide the mandibular lever with additional force and is characteristic of all the so‐called robust australopiths.

robustus crania, but this is because of a secondary elongation of the tympanic at its lateral margin, which often results in the tympanic projecting farther laterally than any other structure on the base.

The discovery of an A. aethiopicus cranium (Walker et al.

The robust australopithecines, members of the extinct hominin genus Paranthropus were bipedal hominids that probably descended from the gracile australopithecine hominids.
