Eye makeup in Northwestern Iran at the time of the Assyrian Empire: a new kohl recipe based on manganese and graphite from Kani Koter (Iron Age III)

Archaeometry, EarlyView.
Abstract Kohl was ubiquitous in ancient Egypt and the Middle East, and routinely included among the toiletries deposited in burials. For Egypt, kohl recipes are increasingly well‐studied and known to use a range of inorganic and organic ingredients. Although these are often lead‐based, manganese‐ and silicon‐rich compounds are also attested.

Greek Commodities in Phoenicia: An Interdisciplinary Study of Imported Amphorae From Tell el‐Burak (Lebanon)

Archaeometry, EarlyView.
ABSTRACT This paper examines transport amphorae of Greek/Aegean types from the 7th–4th c. BCE imported to the Phoenician coastal settlement of Tell el‐Burak, Lebanon. We present a selection of 58 pieces analyzed by typological, chemical (NAA), and petrographic approaches.

Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

Archaeometry, EarlyView.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

Acta Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

Boreas, EarlyView.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.
