    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. New and published foraminifera biostratigraphy results suggest an age of the section within the Mediterranean biozone MMi13d, younger than ~ 6.4 Ma. Calcareous nannoplankton data from sediments exposed near Trachilos and belonging to the same sub-basin indicate deposition during calcareous nannofossil biozone CN9bB, between 6.023 and 6.727 Ma. By integrating the magneto- and biostratigraphic data we correlate the Trachilos section with normal polarity Chron...

    Most recent dating places one wave of human dispersal out of Africa into southeastern Spain at almost one million years ago. Using state-of-the-art dating methodologies, a team of scientists have obtained or confirmed a date range between .9 and .85 Mya (million years ago) as a time when a species of Old World monkey (Theropithecus) and an early species of human occupied the cave site of Cueva Victoria in southeastern Spain. It is a location not far from where many scientists have hypothesized that humans may have crossed over into Europe from North Africa through the Strait of Gibraltar at...
