A badly crushed and distorted cranium found at Lomekwi on the western shore of Lake Turkana in northern Kenya in 1998 was assigned to a new genus and species, “human from Kenya,” Kenyanthropus platyops (3.5 mya). From Wikipedia, the free encyclopedia Australopithecina or Hominina is a subtribe in the tribe Hominini. The genus Paranthropus currently includes three species, Paranthropus boisei, Paranthropus robustus, and Paranthropus walkeri. kadabba (5.8–5.2 mya), which were discovered in the middle Awash River valley in the Afar region of Ethiopia (a depression located in the northern part of the country that extends northeast to the Red Sea), comprise fragments of limb bones, isolated teeth, a partial mandible, and a toe bone. Ar. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelgh… "Australopithecus Profile." The teeth have thick enamel, like the teeth of all later hominins but unlike those of Ar. The fact is that the brains of A. afarensis and A. africanus were only about a third the size of those of Homo sapiens, and there's no convincing evidence, aside from the circumstantial details cited above, that these hominids were capable of using tools (though some paleontologists have made this claim for A. africanus). The earliest species of this genus, Au. Size and Weight: Varies by species; mostly about four feet tall and 50 to 75 pounds They were similar to modern humans in that they were bipedal (that is, they walked on two legs), but, like apes, they had small brains. The two most important species of Australopithecus were A. afarensis, named after the Afar region of Ethiopia, and A. africanus, which was discovered in South Africa. -Bouri is located in the Middle Awash, Ethiopia. The hominid prints were produced by three individuals, one walking in the footprints of the other, making the original tracks difficult to discover. They are collectively known as the ‘robusts’ because of their extremely large jaws and molar teeth. Although similar to other australopithecines, it displayed some surprising features. A. garhi lived about 2.5 million years ago. You can opt-out at any time. Let us know if you have suggestions to improve this article (requires login). Replica of a 3.2- to 3.5-million-year-old. The case for its hominin status rests on the humanlike features of the femur. Several other anatomical characteristics of Ar. Australopithecus: small brain, long arms Homo: broad pelvis, non curved phalanges Their brains were smaller and more in the range of the brains of modern apes. Found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around. Approximate time ranges of sites yielding australopith fossils. It is very long, which allowed its fingertips to extend at least to the knee. The name was originally created just for this species found in South Africa but several closely related species now share the same genus name. O. tugenensis is primitive in most if not all of its anatomy, except for femurs (thighbones) that appear to share traits of bipedalism with modern humans. Australopithecus, means ‘southern ape’. For more details, see our Privacy Policy. afarensis, a species represented by more than 400 fossil specimens from virtually every region of the hominin skeleton. -Australopithecus platyops is one of the most poorly represented hominins. The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus, and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus. Animal fossils, pollen, and other evidence associated with Ar. It is based on ‘australo’, a Latin word meaning ‘southern’ and ‘pithecus’, a Greek word meaning ‘ape’.

The species was first described in 1995 after an analysis of isolated teeth, upper and lower jaws, fragments of a cranium, and a tibia unearthed at the discovery sites. ramidus also indicate that it was at home in a wooded environment (see also Ardi). Like later hominins, it has teeth with thick molar enamel, but, unlike humans, it has distinctively apelike canine and premolar teeth. The skull is apelike with a tiny brain—300–350 cc (18.3–21.4 cubic inches), which is equivalent to a brain weight of about 300–350 grams (10.6–12.3 ounces)—and a prognathic (projecting) snout. Corrections? She lived in Ethiopia 3.2 million years ago. Furthermore, the teeth of some species were more like human teeth. Australopithecus was the first fossil hominid genus to be recovered.

ThoughtCo, Aug. 27, 2020, thoughtco.com/australopithecus-1093049. ramidus (5.8–4.4 mya)—that is, pre-Australopithecus species that are considered to be ancient humans—and one additional species of early human, Kenyanthropus platyops (3.5 mya). Match the species to the best description: Lived from about 4 to 1 million years ago. Australopithecus garhi is one of the last Australopiths, appearing just before the emergence of Homo habilis. Australopithecus is a member of the subtribe Australopithecina, which also includes Ardipithecus, though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. The extremely large hands of the species suggest a lifestyle that included significant climbing and other activities among the trees. The first undisputed evidence of the genus Homo—the genus that includes modern human beings—appears as early as 2.8 mya, and some of the characteristics of Homo resemble those of earlier species of Australopithecus; however, considerable debate surrounds the identity of the earliest species of Homo.

According to its discoverers, features of the thighbone implying bipedalism include its overall proportions, the internal structure of the femoral neck (the column joining the ball-shaped head of the femur to the shaft of the bone), and a groove on the bone for a muscle used in upright walking (the obturator externus). Australopithecus afarensis facts . The material from Laetoli and Hadar (fragmentary remains of 60-100 individuals) constitutes the largest and best-studied assemblage of early hominids. Australopithecus africanus (3 to 2 million years ago) Species Description: Australopithecus africanus was nearly identical in body and brain size to A. afarensis . Retrieved from https://www.thoughtco.com/australopithecus-1093049. The toe bone assigned to Ardipithecus exhibits bipedal anatomy, but it was found in sediments 400,000 years younger than, and some 20 km (12.4 miles) away from, the fossil used to define Ar. Its species were fully bipedal primates with ape-sized brains. The general term australopith (or australopithecine) is used informally to refer to members of the genus Australopithecus. Strauss, Bob.
