Human consumption of seaweed and freshwater aquatic plants in ancient Europe.

During the Mesolithic in Europe, there is widespread evidence for an increase in exploitation of aquatic resources. In contrast, the subsequent Neolithic is characterised by the spread of farming, land ownership, and full sedentism, which lead to the perception of marine resources subsequently representing marginal or famine food or being abandoned altogether even at the furthermost coastal limits of Europe. Here, we examine biomarkers extracted from human dental calculus, using sequential thermal desorption- and pyrolysis-GCMS, to report direct evidence for widespread consumption of seaweed and submerged aquatic and freshwater plants across Europe.

Toothpicking and periodontal disease in a Neanderthal specimen from Cova Foradà site (Valencia, Spain).

We present a Neanderthal maxilla (CF-1) from Cova Foradà site (Oliva, Valencia, Spain) with periodontal disease and evidence of attempts to alleviate pain with the use of a toothpick. Two interproximal grooves have been found on the distal surfaces of the upper left Pm(3) and M(1) of CF-1 maxilla. The location, morphology and size of the grooves coincide with other interproximal grooves found on the teeth of other fossil specimens.

Fire and bones: Bronze Age III in the North-Eastern Iberian Peninsula.

Between the third millennium BP and the fifth century AD, there are numerous necropolises that house urns in the Iberian Peninsula. One example is the "Pi de la Lliura" (Vidreres, Girona). However, there is a dearth of research concerning these structures.

Study of Harris lines at the Prat de la Riba necropolis--third to fifth century AD.

Harris lines (HL) are considered a nutritional or pathological stress factor in the study of past populations. This study attempts to contribute to the knowledge of the causal agents for HL in terms of assessing the health state of the population of Tarragona in the Roman period. The presence of HL has been analyzed in 614 long bones (214 humeri, 150 femurs and 250 tibias) from 243 skeletons.
