This ancient ancestor looked a lot like the iconic "Lucy."
Nearly perfect specimen

A nearly complete Australopithecus anamensis skull has been unearthed in Ethiopia, and it dates to 3.8 million years ago.

The new skull specimen, dubbed "MRD," allowed anthropologists to put a face to the relative of the iconic "Lucy" species.

The fossil skull was found in two pieces in an ancient river delta in the Godaya Valley of the Afar region of Ethiopia. The fossil was buried in sand.

Yohannes Haile-Selassie, a paleoanthropologist at the Cleveland Museum of Natural History, uncovered the fossil in February 2016. Here, Haile-Selassi poses with the cranium.

Similar to "Lucy"

Australopithecus anamensis had a face that was quite similar to the "Lucy" species, Australopithecus afarensis, but with some key differences.
Subtle differences

The hominin's face was not quite as massive and rugged as Lucy's, but it had larger teeth than A. afarensis. MRD's jaw protruded, which is different from the relatively flat faces of modern apes.
Size of a chimpanzee

The ancient hominin would have been about the size of a chimpanzee.
