The analyzed specimen was found in the 1930s by Zotz, in Wschodnia cave (German name Hellmichhöhle, now W Sudeten Mts, Poland). Currently, it is housed in the Archaeological Museum of Wrocław. It is a well preserved splanchnocranium with teeth of an adult Eurasian brown bear. Integral part of the skull is also an intact mandible. Several postcranial skeletal bones were also found for this specimen, including one rib with a human-drilled hole. For the above-mentioned specimen, three C14 datings were made using the AMS method. All three dates gave similar results, allowing the age of the find (after calibration) to be estimated at 14.8-13.8 KY BC, i.e. the Bølling phase of relatively older Dryas. Taxonomic assignation, based on the morphometrical analysis, was confirmed by DNA analysis. It represents subclade 1b, recently identified in Carpathian Mts. The degree of wear of his tooth crowns, especially his incisors and canines, is remarkable, which is completely inadequate to the wear of the remaining teeth and to the individual's age. German researchers suggested that the procedure was performed by a human for ritual purposes. However, the anthropological nature of this find was questioned by Polish researchers, who said that the process was natural and that the abrasion of the front teeth was the result of a malocclusion. Our analyses confirm the earlier assumptions of German scientists that the pathologies visible on the teeth are the result of anthropogenic effects, which was the aim of our research. It is also indirect evidence of the presence of Homo sapiens in the Late Pleistocene of the Sudeten areas of Poland. [ABSTRACT FROM AUTHOR]

In the St. Nicholas Church archaeological site (Libkovice, Czechia; the 18th century cemetery) a female skeleton with a stone object in the left iliac fossa was found. It was a cyst-like structure. The measures of it were 54 mm in length and 35 mm in maximum diameter. Within the object fetal bones (long bones, i.e. femur and two tibias, two scapulas, three ribs, vertebrae and other tiny bone fragments) were revealed. The methods used for the analysis were intended to describe the external and internal morphology of the object and its content: X-ray, CT imaging, SEM, histological staining and EDS. The EDS analysis revealed the presence of primarily oxygen, calcium and phosphorus in bone samples, and oxygen and silicon, in stone shell. The measurements of the femur (20.2 mm) and tibia (16 mm) shafts allowed to estimate the fetal age as the 15-18 week of pregnancy. During the differential diagnosis three most likely cases were taken into account: fetiform teratoma (FT), fetus-in-fetu (FIF) and lithopedion. FT was excluded due to the presence of long bones and their proportions, and due to the presence of an anatomically correct spine. Of the other two possible variants, fetus-in-fetu is more likely than lithopedion, due to the lack of a skull, better development of lower limbs, and low calcium content in the shell. The results do not allow to clearly answer the question which of these two cases is the object due to the insufficient number of similar discoveries in the excavation material. [ABSTRACT FROM AUTHOR]
