Homo habilis, known as 'handy man' is a species of the genus Homo which lived from approximately 2.33 to 1.4 million years ago, during the Gelasian Pleistocene period. Homo habilis. Homo habilis, known as 'handy man' is a species of the genus Homo which lived from approximately 2. Gelasian Pleistocene period. The discovery and description of this species is credited to both Mary and Louis Leakey, who discovered the fossils in Tanzania between 1. Information about the giant shark C.Homo habilis was believed to be the earliest known species of the genus Homo, until 2. Curnoe’s research into Homo gautengensis. Homo habilis. In its appearance and morphology, Homo habilis is the least similar to modern humans of all species in the genus. Homo habilis was short and had disproportionately long arms compared with modern humans, but with a less protruding face than the australopithecines from which it is thought to have descended. Its cranial capacity was less than half of the size of modern humans. Fossil remains are often accompanied by primitive stone tools, hence the soubriquet 'handy man'. Generally, fossil remains demonstrate an australopithecine- like body with a more human- like face and smaller teeth. Some argue Homo habilis was made up of fossil specimens of Australopithecus and Homo. Others argue that Homo habilis and Homo erectus were separate lineages from a common ancestor instead of Homo erectus being descended from Homo habilis . These stone flakes were more advanced than any tools previously used, and gave Homo habilis the edge it needed to prosper in hostile environments previously too formidable for primates. Whether Homo habilis was the first hominid to master stone tool technology remains controversial, as Australopithecus garhi, dated to 2. Homo habilis. However, Homo habilis, possibly because of its early tool innovation and a less specialized diet, became the precursor of an entire line of new species, whereas Paranthropus boisei disappeared from the fossil record. Homo habilis may also have coexisted with Homo erectus in Africa for a period of 5. Agriotherium - Wikipedia. Agriotherium. Temporal range: Late Miocene–Gelasian. Teeth. Scientific classification. Kingdom: Animalia. Phylum: Chordata. Class: Mammalia. Order: Carnivora. Superfamily: Arctoidea. Family: Ursidae. Subfamily. Materials of the late surviving A. Except for the extinct subspecies of modern polar bear Ursus maritimus tyrannus and Arctotherium, Agriotherium was along with the short- faced bear, Arctodus simus the largest member of terrestrial Carnivora. It had dog- like crushing teeth. Its primary diet was carnivorous and secondary was omnivorous possibly classifying this animal as mesocarnivore. With a body mass close to those of most large ungulates (bovines, cervids, camelids, and others), it is probable that Agrotherium could have preyed on these. Agriotherium also likely scavenged, and would not have been hesitant about stealing kills from such animals as the sabertooth cat.
