Signs of meningiomas in a skull of the Mexican colonial period

The skull of a native Mexican from the colonial period is studied. The skull has a nasal trauma, dental pathology and two osteogenic lesions, one situated at the left wing of the sphenoid bone and the other in the infrainion occipital squamous bone, between the left mastoid process and the left occipital condyle. That involving the sphenoid occludes the optic nerve foramen and is evident through the orbit and at pterion. These osteogenic lesions are considered to be secondary to the soft tissue tumour mass, which, at the level of its implantation area, is usually present in meningiomas.     

Simulating archaeologists? Using agent-based modelling to improve battlefield excavations

The study of material culture generated by military engagements has created an emergent sub-discipline of archaeological studies centred on battlefields. This approach has developed a particular and sophisticated methodology that is able to deal with the fact that archaeologists will often not find either structures or a useful stratigraphical record on the site, as the material remains of the battle will basically be metallic objects carried by combatants. It is therefore rather complicated not only to test hypotheses about battle events based on archaeological data, but also to validate the methodology used. Here we propose the use of agent-based models to explore these issues in the case of eighteenth-century battlefield archaeology. The simulation is divided into four different steps. Firstly, a battle is simulated in order to generate realistic virtual archaeological remains left by an engagement between two armies of this era. We then simulate the loss of information that the passing of time produces in the battlefield. The third step involves simulating the archaeological survey, enabling us to explore different survey strategies and the impact on the interpretation of the event itself. Finally, we design a confidence index in order to compare the results of the different virtual excavations using spatial analysis and statistics. The results show that the methodology is fully functional in terms of understanding a battle, and it allows us to suggest new strategies to improve fieldwork and to develop new ways of exploring these particular archaeological sites. It is concluded that the described approach illustrates how simulation can be used to explore methodological issues of archaeological science.     

A case of frontal sinusitis from the Bronze Age site of Can Filuà (Barcelona)

In this study, we present a case of frontal sinusitus with exocranial fistulization in a specimen from the Chalcolithic–Bronze Age period. This is a rare complication of sinusitis, exceptional in paleopathological literature. Copyright © 1999 John Wiley & Sons, Ltd.
