Noninvasive characterization and quantification of anthraquinones in dyed woolen threads by visible diffuse reflectance spectroscopy
The anthraquinone components of the roots of various species of madder (like Rubia tinctorum L. and Rubia peregrina L.) have been used for millennia as red colorants in textiles, carpets, tapestries, and other objects. To understand the selection and preparation of dyestuffs in various cultures and historical periods, these dyes...Chavanne, Clarisse ; Troalen, Lore G ; Fronty, Isabelle Bardies ; Buléon, Pascal ; Walter, Philippe

Middle Jurassic fossils document an early stage in salamander evolution
Salamanders are an important group of living amphibians and model organisms for understanding locomotion, development, regeneration, feeding, and toxicity in tetrapods. However, their origin and early radiation remain poorly understood, with early fossil stem-salamanders so far represented by larval or incompletely known taxa. This poor record also limits understanding of...Jones, Marc E H ; Benson, Roger B J ; Skutschas, Pavel ; Hill, Lucy ; Panciroli, Elsa …

Early Eocene fossil illuminates the ancestral (diurnal) ecomorphology of owls and documents a mosaic evolution of the strigiform body plan
We describe a partial skeleton of a fossil owl (Strigiformes) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Ypresiglaux michaeldanielsi, gen. et sp. nov. is one of the most complete specimens of a Palaeogene owl and elucidates the poorly known ecomorphology of stem group Strigiformes....Mayr, Gerald ; Kitchener, Andrew C

Molecular fingerprints resolve affinities of Rhynie chert organic fossils
The affinities of extinct organisms are often difficult to resolve using morphological data alone. Chemical analysis of carbonaceous specimens can complement traditional approaches, but the search for taxon-specific signals in ancient, thermally altered organic matter is challenging and controversial, partly because suitable positive controls are lacking. Here, we show that...Loron , C C ; Rodriguez Dzul, E ; Orr, P J ; Gromov, A V ; Fraser, Nicholas C …

Nostalgia in the prehistoric archaeological record
Evidence from the prehistoric archaeological record clearly shows that ancient societies had a sense of and engaged with their own histories, be it by reusing, re-appropriating or recreating past material culture. The affective qualities of materials, places and even human remains would have enabled people to remember and connect with...Knight, Matthew G
