Frontiers of Contact: Bioarchaeology of Spanish Florida

The arrival of Europeans in the New World had profound and long-lasting results for the native peoples. The record for the impact of this fundamental change in culture, society, and biology of Native Americans is well documented historically. This paper reviews the biological impact of the arrival of Europeans on native populations via the study of pre- and postcontact skeletal remains in Spanish Florida, the region today represented by coastal Georgia and northern Florida. The postcontact skeletal series, mostly drawn from Roman Catholic mission sites, are among the most comprehensive in the Americas, providing a compelling picture of adaptation and stress in this setting. Study of paleopathology, dental and skeletal indicators of physiological stress, stable isotope (carbon and nitrogen) analysis, tooth microwear, and skeletal morphology (cross-sectional geometry) reveals major alterations in quality of life and lifestyle. The bioarchaeological record indicates a general deterioration in health, declining dietary diversity and nutritional quality, and increasing workload in the contact period. The impact of contact in Spanish Florida appears to have been more dramatic in comparison with other regions, which likely reflects the different nature of contact relations in this setting versus other areas (e.g., New England, New France). The bioarchaeological record represents an important information source for understanding the dynamics of biocultural change resulting from colonization and conquest.     

Fatal wounds in a Late Neolithic double inhumation—A probable case of meningitis following trauma

Among a group of seven skeletons from the southern part of Lower Saxony, dating to the Single Grave Culture (ca. 2500BC ), was a double inhumation, which showed an unusual burial position for one of the individuals interred. Deviating from the typical squatted position, this male was supine. Having been badly injured by an arrow shot into the back, he suffered from post-traumatic paraplegia and, most probably died from bacterial meningitis caused by the flint tip that penetrated the spinal cord. This infection was also responsible for the burial position, clearly pointing to an opisthotonus, which is indicative of the final stage of bacterial meningitis. The other individual, also male, had an arrow wound and died from the complications of a severe wound to the intestines.

Osseous changes due to mastoiditis in human skeletal remains

Mastoiditis is a disease that follows otitis media and may lead to severe endocranial complications. Most studies on mastoiditis and middle ear diseases in archaeological skeletal remains are based on radiological investigations. The following study describes the morphological changes in the pneumatised cells of the mastoid process due to mastoiditis in archaeological skeletal remains, based on macroscopic, endoscopic, light and scanning‐electron microscopic investigations. For the purposes of this study, we used an early medieval Frankish population from Dirmstein, State of Rhineland‐Palatinate, Germany. Copyright © 2008 John Wiley & Sons, Ltd.     

New dinosaur remains from the Late Triassic of southern Brazil (Candelária Sequence,Hyperodapedon Assemblage Zone)

Pretto, F.A., Schultz, C.L., Langer, M.C. 4.02.2015. New dinosaur remains from the Late Triassic of southern Brazil (Candelária Sequence, Hyperodapedon Assemblage Zone). Alcheringa 39, xxx–xxx. ISSN 0311-5518

The oldest unequivocal dinosaurian records come from Upper Triassic strata, mostly from Argentina and Brazil. Recent fieldwork in the Brazilian deposits of Ischigualastian age (late Carnian–earliest Norian) have resulted in the collection of a new specimen (UFRGS-PV-1240-T) identified as dinosaurian by the presence of a concave emargination on the ventral surface of the femoral head and a well-developed deltopectoral crest on the humerus, which extends for ca 40% of its estimated proximodistal length. Although fragmentary, the material increases the dinosaurian record from the Late Triassic of Brazil, which is still modest when compared with coeval Argentine strata. Additionally, UFRGS-PV-1240-T augments the dinosaurian diversity at the ‘Sítio Janner’ site, which was until now restricted to the sauropodomorph Pampadromaeus barberenai. The new specimen is larger than most early dinosaurians (except for herrerasaurids), implying that members of the group were already occupying niches otherwise explored by other larger-bodied taxa in the ‘Sítio Janner’ palaeofauna, and Late Triassic palaeoenvironments in general.

A distinct region of microarchitectural variation in femoral compact bone: Histomorphology of the endosteal lamellar pocket

Bone is a dynamic tissue, responding locally to differential mechanical loading and systemically to hormonal stimuli. Although the tendency is to consider compact bone a homogenous tissue, regional variations in microarchitecture are known to have quite different properties relating to processes of growth and mechanical loading. Specifically, we investigated an example of microstructural variation of the human, adult femoral endocortex, referred to here as the endosteal lamellar pocket (ELP). The femoral ELP is characterised as a histomorphological meta‐feature, made distinct from general circumferential lamellae by its hemicircumferential lamellar orientation, medial positioning, radially oriented Volkmann's canals and decreased presence of Haversian systems. Our preliminary observations of mid‐diaphyseal transverse thin‐ground sections demonstrate the ELP as a regular meta‐feature of adult human femora unearthed from the Maya archaeological site of Xcambó, Mexico. ELPs were easily identified in 38 of 45 examined individuals. Their size, shape and degree of secondary remodelling were variable. In comparison, ELP lamellae and those originating from the periosteum are divergent, or non‐concentric in orientation. This divergence, along with the ELP's medial position, suggest it forms during growth through endosteal modelling drift. Possible considerations for ELP formation and persistence with age are discussed as well as its implications for the study of bone dynamics during growth and activity. Further research is necessary to quantitatively measure the morphology of ELPs and to identify any co‐variance between ELP characteristics and age, sex or indicators of mechanical loading.
