What are the differences between Australopithecus africanus and Australopithecus robustus?
Australopithecus robustus A. robustus had a body similar to that of africanus, but a larger and more robust skull and teeth. It has relatively small front teeth, but massive grinding teeth in a large lower jaw. Most specimens have sagittal crests.
What is the difference between Australopithecus afarensis and Australopithecus africanus?
Australopithecus africanus was nearly identical in body and brain size to A. afarensis. Although the teeth and jaws of A. africanus were much larger than modern human teeth, they are still more similar to ours than to the teeth of apes.
What are the four pre Australopithecus species?
- The australopiths. Early species and Australopithecus anamensis. Ardipithecus kadabba and Ar. ramidus. Australopithecus anamensis. Australopithecus afarensis and Au. garhi. Australopithecus africanus. Australopithecus sediba.
- Relationship to Homo. Quality of the fossil record. Changes in anatomy. Bipedalism. Transition to Homo.
What is the oldest australopithecine?
The 3.5-million-year-old Laetoli canine belonging to Australopithecus afarensis is the oldest hominin fossil in the Museum’s collection. You can see it in the Human Evolution gallery.
How old is Australopithecus robustus?
Paranthropus robustus lived between 2 and 1.2 million years ago. Dental studies suggest the average Paranthropus robustus rarely lived past 17 years of age.
What is unique about Australopithecus africanus?
Au. africanus was anatomically similar to Au. afarensis, Au. africanus had a rounder cranium housing a larger brain and smaller teeth, but it also had some ape-like features including relatively long arms and a strongly sloping face that juts out from underneath the braincase with a pronounced jaw.
What is the best known australopithecine?
Australopithecus afarensis is the most well known species, partly because of the famous “Lucy” skeleton (A.L. 288-1), and partly because it is known from most skeletal elements from male and female, young and old individuals. Much of our understanding of hominin origins is based on A.
What did the Australopithecus afarensis eat?
Au. afarensis had mainly a plant-based diet, including leaves, fruit, seeds, roots, nuts, and insects… and probably the occasional small vertebrates, like lizards.

What did Australopithecus robustus look like?
They are characterized by several features of the skull that give them a “robust” appearance when compared to other, more gracile hominins. The most notable of these features are large, thickly enameled, postcanine teeth that were supported by deep and broad mandibular corpora with tall and broad rami (Fig.
