An international multi-disciplinary team of scientists have determined that a well-known group of early Homo (early human) fossils discovered in previous investigations at Koobi Fora in the Turkana Basin of East Africa have an age range that is older than previously estimated.

Led by archaeologist Josephine C.A. Joordens of the Netherlands' Leiden University, the researchers combined magnetostratigraphy and strontium (Sr) isotope stratigraphy techniques to develop a new age constraint range for 15 selected hominin fossils found in deposits on the Karari Ridge of the Koobi Fora region in the eastern Turkana Basin (Kenya).
