The First Quantitative Evidence of Ontogenetic Growth in the Early Cambrian Ecdysozoan Worm Cricocosmia jinningensis Reveals the Earliest Energy Reallocation

open access: yesIntegrative Zoology, EarlyView.
We report the first ontogenetic information for the compression‐preserved Cambrian ecdysozoan worm Cricocosmia jinningensis. Its mosaic growth strategy unifies panarthropod and priapulid developmental patterns. Sclerite allometry reverses at the juvenile‐to‐adult transition, providing the earliest evidence of developmental resource allocation ...

Greek ΜΝΗΣΘΗ and Aramaic DKYR in the Near East: A Comparative Epigraphic Study

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Past studies of graffiti containing the word ΜΝΗΣΘΗ have never fully established its intrinsic meaning. However, due to the existence of the Aramaic term DKYR, which carries a seemingly identical meaning to ΜΝΗΣΘΗ, in similar contexts in the Roman Near East, a comparison between both words is possible. Four distinct sites where the coexistence

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

open access: yesArchaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Learning Across the Divide: Understanding Knowledge Sharing Through Petrographic Analysis on Ceramics From the Rhine‐Meuse Delta During the Middle to Late Neolithic Transition (3400–2200 bce)

open access: yesArchaeometry, EarlyView.
ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.
