The preservation of bone or bioapatite over geologic time has presented paleobiologists
with long-standing and formidable questions. Namely, to elucidate the mechanisms …

Advances in technology over the past two decades have resulted in unprecedented access
to data from biological specimens. These data have expanded our understanding of …

A combined investigation by X-ray fluorescence (XRF), Fourier Transform Infrared
spectroscopy (FT-IR), Raman spectroscopy and powder X-ray Diffraction (XRD) …

Chloride ion transport in alkali silicate powder and liquid activated slag concretes, and the
influence of the material microstructure are discussed. Increasing the Na2O-to-slag ratio (n) …

Elemental maps generated by laser ablation–inductively coupled plasma–mass
spectrometry (LA-ICP-MS) provide a previously unavailable high-resolution visualization of …

Evolution of flight in maniraptoran dinosaurs is marked by the acquisition of distinct avian
characters, such as feathers, as seen in Archaeopteryx from the Solnhofen limestone. These …

We examined by Rietveld refinement of X-ray Diffraction patterns a series of 61 human and
animal fossil bones in an age range from present time to Middle Triassic (around 245Ma) …

Simple Summary Contrary to traditional views, fossil bones have been shown to
occasionally retain original cells, blood vessels, and structural tissues that are still …

Sarahsaurus aurifontanalis, from the Kayenta Formation of Arizona, is one of only three
sauropodomorph dinosaurs known from the Early Jurassic of North America. It joins …

Current understanding of bone healing and remodelling strategies in vertebrates has
traditionally relied on morphological observations through the histological analysis of thin …
