Developmental Stress in Immature Hominines from Late Pleistocene Eurasia: Evidence from Enamel Hypoplasia

The differences between Middle and Upper Palaeolithic cultures from Europe have been likened to the contrast between generalized and complex hunter–gatherers. A test of this model is undertaken by comparing the types, amount, severity and timing of episodes of enamel hypoplasia between the two periods among specimens from western Europe and the circum-Mediterranean area. The earlier sample consists of 59 dentally immature individuals with 128 primary and 154 permanent teeth while the later sample consists of 47 dentally immature individuals with 162 primary and 125 permanent teeth. It was predicted that the Upper Palaeolithic would show more variation in the attributes noted above as a consequence of increased social differentiation. While the prevalence (50% of individuals) and severity of enamel hypoplasia do not differ between the samples, the Upper Palaeolithic component is significantly more variable in the types and timing of enamel defects. Localized hypoplasia of the primary canine is absent from the Middle Palaeolithic but very common among Upper Palaeolithic children. Earlier work has linked this enamel defect to craniofacial osteopenia due to low bioavailability of vitamin A. Linear enamel hypoplasia peaks at age 3·5 years in the Middle Palaeolithic sample but is as common at age 2·0 as 5·0 years in the Upper Palaeolithic sample. The age distribution differs significantly. Peak age at stress, combining all types of enamel hypoplasia, is 3·5 years in the Middle Palaeolithic and 0·5 years in the Upper Palaeolithic. The major contrast between the Middle and Upper Palaeolithic in terms of enamel hypoplasia is the advent of stressful episodes in early infancy in the Upper Palaeolithic. This is attributed to the low bioavailability of vitamin A due to the synergistic effects of malnutrition and infection exacerbated by a net increase in population density among socially competitive family lineages.     

‘Halt! Be Men!’: Sikelgaita of Salerno,Gender and the Norman Conquest of Southern Italy

This article examines the career of Sikelgaita (1040–1090), wife of the Norman conqueror of southern Italy, Robert Guiscard, as a means of understanding the impact of the ‘other’ Norman conquest of the eleventh century. Sikelgaita is unusual in that she has left images in narrative sources both within and well beyond the confines of southern Italy. She is also well documented at a local level. Both types of material combine to reveal her crossing gender boundaries in titles she used, the way in which she managed property, her legendary presence alongside Robert on his campaigns and, more speculatively, in organising a campaign of written propaganda to ensure the succession of her son to his father's patrimony in preference to his half‐brother by Sikelgaita's predecessor as Robert's wife. Her history raises the problems of women's access to written texts, their conscious shaping of their own identities, their conflicting loyalties between natal and marital families, and the need for competing male heirs to prove themselves against a prevailing notion of masculinity in a period when one aggressively masculine group, the Lombards, was being supplanted in power by another, the Normans. As such, it demonstrates that the lives of so‐called ‘exceptional’ women continue to have a value to historians of gender in the middle ages, and can often demonstrate the patriarchal boundaries which even they could not cross.     

Examining criteria for identifying and differentiating fossil faunal assemblages accumulated by hyenas and hominins using extant hyenid accumulations

Numerous authors have put forth criteria for distinguishing between assemblages collected by hyenas and hominins. Of the seven most recognised criteria used to distinguish hyenid from hominin assemblages, it has recently been suggested that four be rejected and three retained. The four rejected criteria are: an excessive proportion of horns and horn cores in hyena accumulated assemblages; the absence of small, hard, compact bones; mortality profiles; and the ratio of cranial bones to postcranial bones. The three criteria previous researchers suggested be retained are: a carnivore MNI ratio of ≥20%; an abundance of cylinder fragments; and hyena‐inflicted damage upon the bones. In this examination of over 27,000 faunal remains associated with all three species of extant bone‐collecting hyenids from four countries and two continents, six of the seven previously established criteria and reconsiderations of criteria have been evaluated. The results of the present study indicate that of the six criteria examined, none, as written, are indicative of hyenid activity on bone assemblages of unknown origin.
