Dr. Yohannes Haile-Selassie began intensive and systematic field research in the Woranso-Mille area after 3 years of surveying the Afar desert and formed the Woranso-Mille paleoanthropological research project (WORMIL).
The Woranso-Mille paleontological site is located in the western part of the central Afar depression and about 35 km north of Hadar, Gona, and Dikika, and shares its southern border with Ledi-Geraru.
Since then, 85 vertebrate paleontological localities have been designated with close to 10,000 fossil specimens cataloged, including more than 120 hominin fossils. The faunal assemblage includes more than 70 mammalian species, with most of the specimens recovered from sediments dated to between 3.207 and 3.82 Ma.
The WORMIL project has recovered some of the most important hominin fossils, including a partial skeleton of Australopithecus afarensis ("Kadanuumuu"), an as-yet-unnamed partial foot ("Burtele Foot") that proved multiple modes of locomotion in middle Pliocene hominins, and Australopithecus deyiremeda, a new hominin species that co-existed with Australopithecus afarensis in Woranso-Mille.
