scientists from the same Haile-Selassie team announced the discovery of a nearly intact skull for the first time, and dated to 3.8 mya, of A. anamensis in Ethiopia. This discovery also indicated that an earlier forehead bone fossil from 3.9 mya was A. afarensis and therefore the two species over-lapped and could not be a chronospecies (noting that this does not prevent A. afarensis being descended from A. anamensis, but would be descended from only part of the A. anamensis population). The skull itself was found by Afar herder Ali Bereino in 2016. Other scientists (e.g. Alemseged, Kimbel, Ward, White) cautioned that one forehead bone fossil, which they viewed as not conclusively A. afarensis, should not be taken as disproving the possibility of anagenesis yet. In August 2019, scientists announced the discovery of a nearly intact skull, for the first time, and dated to 3.8 million years ago, of A. anamensis in Ethiopia. The skull itself was found by Afar herder Ali Bereino in 2016. This skull is important in supplementing the evolutionary lineage of hominins. The skull has a unique combination of derived and ancestral characteristics. It was determined that the cranium is older than A. afarensis through analyzing that the cranial capacity is much smaller and the face is very prognathic, both of which indicate that it is earlier than A. afarensis. Known as the MRD cranium, it is that of a male who was at an "advanced developmental age" determined by the worn down post-canine teeth. The teeth show mesiodistal elongation, which differs from A. afarensis. Similar to other australopiths, however, it has a narrow upper face with no forehead and a large mid-face with broad zygomatic bones. Before this new discovery, it was widely believed that Australopithecus anamensis and Australopithecus afarensis evolved one right after the other in a single lineage. However, with the discovery of MRD, it suggests that A. afarensis did not result from anagenesis, but that the two hominin species lived side by side for at least 100,000 years. Environment Australopithecus anamensis was found in Kenya, specifically at Allia Bay, East Turkana. Through analysis of stable isotope data, it is believed that their environment had more closed woodland canopies surrounding Lake Turkana than are present today. The greatest density of woodlands at Allia Bay was along the ancestral Omo River. There was believed to be more open savanna in the basin margins or
