Age constraints for the Trachilos footprints from Crete [PDF]

open access: yesScientific Reports, 2021
We present an updated time frame for the 30 m thick late Miocene sedimentary Trachilos section from the island of Crete that contains the potentially oldest hominin footprints. The section is characterized by normal magnetic polarity.
