Preliminary study on dinosaur rib microstructure by applying correlative microscopy techniques

摘要: A dorsal rib portion from the post-cranial skeleton of a small ornithischian dinosaur discovered fossiliferous locality in Boseong was analyzed through Optical Microscopy (OM), Scanning Electron (SEM), Probe Microanalyser (EPMA), X-ray Diffraction (XRD), and Transmission (TEM) to determine detailed microstructure components fossilized bone. The bone specifically chosen as an initial research sample establish efficient experimental methodology order apply future osteohistological study. Since highly compressed by surrounding matrix, distinct features tissues were not clearly visible OM cross sections. Instead, we observed two other features: (1) numerous patches calcite crystals various orientations filling void region; (2) apatite 10∼200 nm size constituting matrix region, which is revealed XRD, EPMA, SEM, TEM. data have obtained so far preliminary directly elucidate specific microstructural properties such formation growth patterns, but provided possibility revealing characteristic nano-scale established specimen preparation methods for correlative (OM)-Electron (EM)
