    A step back to move forward: a geological re‐evaluation of the El Castillo Cave Middle Palaeolithic lithostratigraphic units (Cantabria, northern Iberia)
    (Wiley, 2022-08-28) Martín Perea, David M.; Maíllo Fernández, José Manuel; Marín Hernando, Juan; Arroyo, Xabier; Asiaín, Raquel; https://orcid.org/0000-0002-3238-0904
    El Castillo Cave is one of the most important sites for understanding the Middle and Upper Palaeolithic in Europe. Despite its importance, the absence of a widely used stratigraphic section with detailed lithostratigraphic descriptions and correlations between the different geological and archaeological interpretations has led to confusion in the correct identification of lithostratigraphic units in the lowermost, Middle Palaeolithic sequence. This study establishes a new lithostratigraphic framework for the site, which can be accurately correlated to previous geological and archaeological studies and generates a solid working basis for framing the Mousterian of El Castillo Cave in the Cantabrian region and southwestern Europe. The geological re‐evaluation of Unit XX (‘Mousterian Alpha’) has expanded its chronology, now ranging from 49 130–43 260 cal BP to 70 400 ± 9600 BP. Unit XXII (‘Mousterian Bet’) would consequently yield an age older than 70 400 ± 9600 BP and younger than the underlying speleothem (Unit XXIIIb), dated to 89 000 +11 000/‐10 000 BP.

    Geology and chronology of the Ndutu and Naisiusiu type sites: implications for Middle and Later Stone Age occupations at Olduvai Gorge (Tanzania)
    (Elsevier, 2025-08-18) Martín-Perea, David Manuel; Medialdea, Alicia; Marín Hernando, Juan; Abellán Beltrán, Natalia; Solano-Megías, Irene; Arteaga, Carlos; Rodríguez-Hidalgo, Antonio; Uribelarrea, David; Arroyo, Xabier; Gidna, Agness; Mabulla, Audax; Maíllo Fernández, José Manuel
    Olduvai Gorge (northern Tanzania) preserves a rich and continuous paleoanthropological record spanning the past two million years. While its Early Stone Age occupations have been intensively studied, the Middle and Later Stone Age sequences, represented by the Ndutu and Naisiusiu Beds, remain less understood. This study presents new geological and geochronological data from the type localities of the Ndutu and Naisiusiu Beds. Using optically stimulated luminescence (OSL), we establish a revised chronological framework for these sedimentary units. The Lower Ndutu Beds, composed of fluvially reworked conglomerates and sands capped by a trachytic tuff and silts, are now dated between 152.9 ±11.6 ka and 122.9 ±8.3 ka. The Upper Ndutu Beds include archaeologically rich sandy and silty facies and are dated between 86.9 ±4.5 ka and 70.8 ±10.4 ka. At the Naisiusiu type site, a sequence of fluvial, sheetwash, and aeolian deposits yielded OSL dates ranging from 65.3 ±4.4 ka to 32.8 ±2.2 ka, suggesting that the LSA occupation at Olduvai began significantly earlier than previously assumed. These results provide refined age estimates for the Middle and Later Stone Age deposits at Olduvai Gorge and confirm a relatively rapid transition between these two technocomplexes during the Late Pleistocene. The data strengthen regional correlations with sites like Nasera and Mumba, providing critical chronological resolution to ongoing debates about the tempo and mode of behavioural evolution in eastern Africa.
