The bone wall is fairly thick, with a RBT of about 31%. It largely comprises of parallel−fibred bone tissue, in which several rest lines are recognizable. The bone is generally poorly vascularized, except for a localized area in the region of drift, the osteocytes tend to be haphazardly oriented, and a few channels for blood vessels are visible in the compacta (Fig. 9A).</p> <p>Femur.—The Barunlestes femoral sample examined comprised only a small fragment. The section shows an outer parallel−fibred bone tissue with several LAGs (Fig. 9B 1, B 2). In a localized part of the section, there appears to be a bone tissue with more globular haphazardly oriented osteocyte lacunae</p> <p>(Fig. 9B 2), which may be correlated with a faster rate of bone deposition.</p> <p>Extant eutherian</p> <p>Heterocephalus glaber (Fig. 10).—Cross sections of the femur display a rather thick bone wall, with an average thickness of about 0.8 mm and a RBT of about 30%. Two distinct regions are clearly visible in the bone wall: a poorly vascularized outer circumferential layer (OCL) that consists of a parallel−fibred bone tissue, and an inner, richly vascularized region consisting of a more woven type of bone tissue. The perimedullary region of the bone is uneven and highly resorptive. Several radially oriented vascular channels extend from the medullary cavity to the mid cortical part of the bone wall. The vascular channels lack osteonal development around them. Although some enlarged erosion cavities are visible in the compacta, no secondary osteons were observed (Fig. 10).</p> </div>	https://treatment.plazi.org/id/03FA87C99E3EFFC1FCFAF9E0FC515CF1	Public Domain	No known copyright restrictions apply.
