Minimally Destructive Radiocarbon Dating of Bone

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 9, 15 May 2026.
ABSTRACT Rationale Bone is commonly used in radiocarbon dating in archaeology and other disciplines. Despite advances in collagen extraction protocols, the process remains destructive, requiring sawing, drilling or crushing of bone material. While non‐destructive approaches have recently been applied in ancient genomics and palaeoproteomics, no ...

PIA : more accurate taxonomic assignment of metagenomic data demonstrated on sedaDNA from the North sea [PDF]

open access: yes, 2020
Assigning metagenomic reads to taxa presents significant challenges. Existing approaches address some issues, but are mostly limited to metabarcoding or optimized for microbial data. We present PIA (Phylogenetic Intersection Analysis): a taxonomic binner

Palynological, tephra, and 14C records from southern Kaitoke, Great Barrier (Aotea) Island, New Zealand, since c. 30,000 cal. yr BP

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 5, Page 1096-1114, December 2025.
ABSTRACT Here we present results of the last remaining three, unreported pollen and stratigraphic profiles from our previous investigations on Great Barrier Island from southern Kaitoke. The 14C and pollen data extend the island's previous maximum pollen‐vegetation date from c. 7000 cal. yr BP to close to the end of MIS 3 c. 30,000 cal. yr BP.

Human Coprolites as a Source for Paleomicrobiology

open access: yesMicrobiology Spectrum, 2016
The paleomicrobiology of coprolites, which are fossilized fecal materials, has already yielded data about various organisms, including micro-eukaryotes, bacteria, and archaea, thus expanding our comprehension of ancient human dietary habits, gut microbiota, and intestinal and systemic infections.
