Australopithecus deyiremeda

Australopithecus deyiremeda is an extinct hominin species known from fossil remains in Ethiopia’s Afar Region, dated to about 3.5–3.3 million years ago.

Woranso-Mille: Woranso-Mille is a fossil-bearing area in Ethiopia’s Afar Region that preserves Pliocene hominin remains. The species’ known fossils were recovered from this area.
Dental morphology: Dental morphology is the form and structure of teeth, including their crowns, cusps, and enamel. Tooth shape and size are central evidence used to distinguish the species.
Yohannes Haile-Selassie: Yohannes Haile-Selassie is an Ethiopian paleoanthropologist who has led research on hominin fossils from the Afar Region. He led the team that described the species in 2015.
Hominin phylogeny: Hominin phylogeny is the evolutionary history and pattern of relationships among hominins. Its position relative to other australopiths remains difficult to establish.
Burtele: Burtele is a fossil site in Ethiopia’s Afar Region known for Pliocene hominin remains and associated animal fossils. Fossils attributed to this species were found at the Burtele locality.
Dental microwear: Dental microwear is microscopic damage on tooth surfaces produced by food and other materials during chewing. Microscopic tooth traces can help test ideas about what its members ate.
Paleoanthropology: Paleoanthropology is the study of human evolution through fossil and archaeological evidence. The species was established through comparative study of fossil hominins.
Species problem: The species problem is the difficulty of defining and identifying species consistently across biology. Limited fossils make the distinctness of this species a question of classification.
Mille-Logya: Mille-Logya is a sedimentary basin in Ethiopia’s Afar Region containing Pliocene fossil deposits. Its geological setting helps locate the deposits that yielded the species.
Stable isotope analysis: Stable isotope analysis measures isotope ratios in materials to infer past diets, environments, or biological processes. Isotope evidence offers a route to reconstructing its diet and habitat.
