Aloyce Mwambwiga defended his doctoral thesis today! He is a scholar I respect for his consistency and integrity, even as we navigated the most extreme challenges There’s now a new phytolith lab in Tanzania, equipped. He will be directing it, for the science to be practiced locally Cheers!!

Auto-fluorescent phytoliths: can we detect past fires in tropical and subtropical contexts? - Vegetation History and Archaeobotany

To understand human practices and landscape evolution it is crucial to be able to trace evidence of past fires, notably in tropical environments. In such anthromes, phytoliths are generally well prese...

Evidence for Endogenous Collagen in Edmontosaurus Fossil Bone

Reports of proteins in fossilized bones have been a subject of controversy in the scientific literature because it is assumed that fossilization results in the destruction of all organic components. I...

This is the first of four papers building the case that hominins practiced landscape fire management in Central Asia (dating to 600 ka). This paper establishes the preservation context for biomarkers at the sites. Later papers will evaluate the broader ecological and evolutionary implications.

Occurrence and distribution of biomarkers in loess-paleosol sequences of Tajikistan (Central Asia): Implication for archaeo-ecological studies

Finding biomarkers preserved in loess-paleosol sequences is challenging and rarely undertaken in the archaeological studies that occur in these settin…
