“…We studied the rib cortical bone because it is easier to observe variations in its preservation and to extract DNA for histological study. We believed that in this material, the state of conservation must show the gradient of taphonomic alterations produced by environmental factors such as the presence of water, pH or soil acidity, and the presence of biotic agents such as fungi and bacteria (von Endt & Ortner 1984, Lambert et al 1985, Boddington 1987, Henderson 1987, Micozzi 1991.…”

“…Mn, besides being incorporated into the oxides, is known as a contaminant of the calcium carbonate from soil solution [27]. Enrichment of Fe in fossil bones has been observed previously by [25,1]. The distribution of Fe, which mainly covers the inner surface of the voids created by the degeneration of organic parts, might indicate that the iron oxides formed at an early stage of the diagenetic process.…”

Sauropod dinosaurs were typically one magnitude larger than any other living or extinct terrestrial animal. This sheer size of the sauropod leads to scale effects in their biology and physiology that still are inadequately understood. The only remnants of the sauropods are their fossilized bones. These fossilized bones have sustained burial for some hundred million years and thus may have experienced significant diagenetic changes. These diagenetic changes often do not affect bone preservation on the histological level, but may lead to significant alterations of the bone microstructure. Here the influence of diagenesis on the microstructure of fossilized sauropod bones using femur cross-section of Brachiosaurus brancai that was excavated in the Tendaguru beds in Tanzania is investigated. The element distribution in this dinosaur bone is studied by a combination of micro-X-ray-fluorescence (µ-XRF) using synchrotron radiation and energy dispersive X-ray analyses (EDX) in the scanning electron microscope. These techniques reveal quantitative values of the element concentration at a macroscopic level combined with qualitative information at high spatial resolution of the distribution of Ca, Co, Cr, V, Pb, U, Sr, Y, and As in the fossil bones. This allows a differentiation between the remnants of the original bone apatite and pore filling minerals and also a visualization of damage, e.g. cracks introduced by diagenetic processes.

“…The mean Mn concentration in the bones was higher than that in the soil, whereas the elements were lower. Many studies about toxic metal and trace element analysis have been carried out to reveal the paleodiet and life conditions of ancient populations [7,13,14]. Pb, Zn, Cu, Ni, and Fe are accumulated in bones in different degrees and for different reasons.…”

The presence of copper, zinc, magnesium, iron, lead, molybdenum, manganese and nickel was discovered on 22 human ribs in a Hellenistic-Roman cemetery located in the ancient city of Camihöyük, Turkey. The levels of each element found in the males were higher than those in females, except iron. Copper, magnesium, iron, molybdenum, and nickel levels were measured to be higher in the soil than in the skeletons, whereas the other elements were higher in the human skeletons. Lead was not traced in the soil, but on the skeletons. These individuals had probably been exposed to this element during their lives due to higher consumption of vegetables than meat.
