“…Their histology is similar to that of regular bone (Moodie, 1928;Organ and Adams, 2005;Zhou et al, 2010). It is possible that the trochanteric shelf in some dinosaurs is of such origin (Raath, 1990;Nesbitt et al, 2009 (Fig.…”

A principal component analysis (PCA) performed for a set of 24 measurements on 33 femora and 15 measurements on 20 ilia of Silesaurus opolensis from the early Late Triassic of Krasiej ow, southern Poland, shows that this sample is highly variable but probably monospecific. Most of the morphological variation is concentrated in the muscle attachments and proportions of bones, which significantly change in both size and position during ontogeny. Despite the small sample size, femora of smaller individuals have less flattened shafts and a more sinusoidal appearance. In many large specimens, proximal parts of muscle tendons are ossified at their attachment site on femora and remain attached to the bone in the largest specimens. The specimens with attached ossifications are interpreted as mature females that were statistically larger than proposed males. It is suggested that ossifications developed in females under calcitonin control. The intrapopulation variability of ilia is high, but less dependant on ontogeny. The population represented by a few specimens from the lower level at Krasiej ow may represent a different stage in the evolution of the species than that from the upper horizon.

“…Another type of ossified tendon, or rather ligament, is that seen in many dinosaurs (Organ and Adams, 2005). They are found mainly in the Ornithischian dinosaurs, where they are found only in the vertebral column.…”

“…The study of dinosaur bone histology has provided a great deal of information about bone formation, skeletochronology, physiological factors such as metabolism, growth rates, and reproductive strategies by carefully inspecting and evaluating the distinctive histological features of dinosaur bones (Biltz et al, 1969;Chinsamy, 2005;Erickson, 2005;Erickson et al, 2009;Goodwin et al, 2007;Organ and Adams, 2005;Schweitzer et al, 2005;Ricqles et al, 2008;Stark and Chinsamy, 2002). There are also ongoing studies regarding the debates and controversial issues based on dinosaur osteohistological features (Laing, 2001;Martill and Unwin, 1997;Kolodny et al, 1996).…”

Preliminary study on dinosaur rib microstructure by applying correlative microscopy techniques

et al. 2011

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