Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Grains of truth or transparent blindfolds?:A review of current debates in archaeological phytolith analysis [PDF]

, 2013
Phytolith analysis has become an increasingly popular archaeobotanical tool in the past few decades. Phytoliths have been used to support key hypotheses relating to the domestication of several food crops and in the study of ancient diet, and they are of

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

Pollen and phytoliths from fired ancient potsherds as potential indicators for deciphering past vegetation and climate in Turpan, Xinjiang, NW China. [PDF]

PLoS ONE, 2012
It is demonstrated that palynomorphs can occur in fired ancient potsherds when the firing temperature was under 350°C. Pollen and phytoliths recovered from incompletely fired and fully fired potsherds (ca.

The Meaning of Mangabey Molars (And Premolars)

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT The postcanine teeth of mangabeys (members of Cercocebus and Lophocebus) have figured prominently in discussions about the relationship between hard‐object feeding and dental form. Grey‐cheeked mangabeys (Lophocebus albigena) and sooty mangabeys (Cercocebus atys) both have thickly enameled posterior teeth.

Decoupling the Spread of Grasslands from the Evolution of Grazer-type Herbivores in South America [PDF]

, 2013
The evolution of high-crowned cheek teeth (hypsodonty) in herbivorous mammals during the late Cenozoic is classically regarded as an adaptive response to the near-global spread of grass-dominated habitats.

The Phytoliths in the Flora of Ecuador project: Perspectives on phytolith classification, identification, and establishing regional phytolith databases [PDF]

Journal of Archaeological Science, 2016
Abstract The Phytoliths in the Flora of Ecuador project was undertaken to establish diagnostic phytolith types and phytolith vegetation signatures to enhance archaeological and paleoenvironmental phytolith applications in the region. In this paper I discuss the “products” of this research, and provide links to on-line resources.
