Medieval mass burial in Pereslavl-Zalessky

The paper presents the results of the anthropological study of a mass grave located in the grounds of the kremlin of Pereslavl-Zalessky (European Russia). It has been preliminary dated to the 13th — first half of the 14th century. This study is aimed at craniological investigation and establishing anthropological connections of the Medieval population of Pereslavl-Zalessky, as well as clarification of the circumstances of appearance of the mass burial within the town territory with the aid of anthropological methods. The human remains were analyzed to identify the number of individuals and to determine their sex and age. Determination of sex and age and recording of injuries were carried out on the craniological material. The craniological program was used to study 28 male and 16 female skulls. A canonical discriminant analysis was used for the intergroup analysis. The mass burial contained separated bones of 80 adults and 19 children. It was possible to identify 30 males and 24 females. The male component of the group was represented by virtually all age groups. The female part comprised mainly women aged 20–35. Therefore, the interred were placed in the grave spontaneously, considerably later after their death; the bodies had time to decompose completely. Eleven instances of skull injuries without signs of necrotic process and healing were recorded. The location and characteristics of the burial and presence of several instances of fatal lacerated wounds indicate that the city residents died in the course of a military clash. Therefore, the studied series represents a time slice of the population of the medieval city. The canonical discriminant analy-sis on the craniological series of 53 revealed that the studied series is distinct from the territorially and chronologically close series of Yaroslavl and Kostroma Krivichs. It also showed that the formation of the population of Pereslavl-Zalessky was strongly influenced by the migration of the Ilmen Slovens and Smolensk-Polotsk Krivichs. Among the specifics of the Pereslavl series, also noteworthy is the strong influence of southern Russian migrants. On the contrary, the influence of the Finno-Ugric morphological component on the urban population of the 13th–14th centuries was very insignificant.

Strong but not Unbeatable: Two Cases of Healed Severe Skull Trauma in Males Buried in Medieval Mass Graves (Kutná Hora-Sedlec, Czech Republic)

This paper presents two cases of healed skull trauma recovered from medieval mass burial sites in Kutná Hora-Sedlec (Kutná Hora District/CZ). These recently unearthed burial pits are historically and contextually associated with two key catastrophes: (1) a famine in the early 14th century; and (2) the Black Death in the mid-14th century. The first skull presents evidence of survival from severe cranial injury with highly probable surgical intervention. The second one presents evidence of successful skull surgery, confirming the practice of trepanation performed by a skilled specialist in a given region at a given time in history. Although both individuals had been robust enough to withstand the pain and strain of the treatment, indicating considerable resilience to survive the skull trauma, they succumbed to mass infection or famine that killed a large number of inhabitants of this prominent medieval mining region.

Geology and taphonomy of a unique tyrannosaurid bonebed from the upper Campanian Kaiparowits Formation of southern Utah: implications for tyrannosaurid gregariousness

Tyrannosaurids are hypothesized to be gregarious, possibly parasocial carnivores engaging in cooperative hunting and extended parental care. A tyrannosaurid (cf. Teratophoneus curriei) bonebed in the late Campanian age Kaiparowits Formation of southern Utah, nicknamed the Rainbows and Unicorns Quarry (RUQ), provides the first opportunity to investigate possible tyrannosaurid gregariousness in a taxon unique to southern Laramidia. Analyses of the site’s sedimentology, fauna, flora, stable isotopes, rare earth elements (REE), charcoal content and taphonomy suggest a complex history starting with the deaths and transport of tyrannosaurids into a peri-fluvial, low-energy lacustrine setting. Isotopic and REE analyses of the fossil material yields a relatively homogeneous signature indicating the assemblage was derived from the same source and represents a fauna living in a single ecospace. Subsequent drying of the lake and fluctuating water tables simultaneously overprinted the bones with pedogenic carbonate and structurally weakened them through wet-dry cycling. Abundant charcoal recovered from the primary bone layer indicate a low temperature fire played a role in the site history, possibly triggering an avulsion that exhumed and reburied skeletal material on the margin of a new channel with minimal transport. Possible causes of mortality and concentration of the tyrannosaurids include cyanobacterial toxicosis, fire, and flooding, the latter being the preferred hypothesis. Comparisons of the RUQ site with other North American tyrannosaur bonebeds (Dry Island-Alberta; Daspletosaurus horneri-Montana) suggest all formed through similar processes. Combined with ichnological evidence, these tyrannosaur mass-burial sites could be part of an emerging pattern throughout Laramidia reflecting innate tyrannosaurid behavior such as habitual gregariousness.

Geophysical Investigations of United States Revolutionary War Era (1777–1778) Mass Burial Sites in Pennsylvania, USA

The United States Revolutionary War (1775–1783) resulted in numerous mass burials in the eastern United States, with deaths occurring not just directly related to the battles fought, but also from disease, starvation, and exposure. Current information relating to these mass burials is often gathered from myths and rumors, leaving the truth of the historical aspects of that time period ambiguous. Geophysical techniques are increasingly utilized in archaeologic and forensic studies to locate unmarked burials. GPR, magnetics, and electrical resistivity have been used to successfully identify burial locations around the world in a non-invasive manner. This paper aims to illustrate how different burials of the US Revolutionary War period can be detected and characterized with geophysics, providing important knowledge of a better historical understanding of that time period, as well as optimizing equipment instrumentation and processing procedures for such targeted investigations. Three case studies of Revolutionary War Era mass burial sites in Pennsylvania, USA are described here: the Paoli Battlefield Memorial, the Old Charlestown Cemetery, and Saint Peter's Church in the Great Valley. These sites are within 9 km of each other and have historic records that suggest mass burials during this period. Results show GPR to provide the most useful data overall, with supporting information gathered from the supplemental geophysical techniques of magnetometry and resistivity. 2D profiles tend to provide a more valuable image of the subsurface than 3D slices. Larger burials leave a greater footprint and have a higher chance of causing a geophysical disturbance that can be measured more than 200 years after the burial. Soil moisture content and vegetation type can impact quality of results. Study implications demonstrate the challenges and potential usefulness of geophysical techniques to successfully locate and characterize mass burials of this time period.
