Only the presence of former vascular spaces can be discerned within the completely altered bone matrix. Towards the cancellous interior, there appears a wavy border, internal to which the fossil bone matrix is still pristine and its microstructure is well discernible. Here the cortex reveals a meshwork of ISF. The cortex is vascularized by scattered primary osteons. There is no clear transitional zone to the cancellous bone as evidenced by large scattered secondary osteons and erosion cavities lined with lamellar bone (Fig. 6b). Whether the external-most ornamental part of the of shell bone consisted of the same ISF matrix as the more internal part cannot be elucidated (Fig. 6c).</p> <p>Cancellous bone—The vascular spaces in the interior area of the bone are small, round to oval-shaped, mostly lined with lamellar bone, and separated by interstitial primary bone. Only a few small trabeculae formed between adjacent vascular spaces, but those are not secondarily remodelled.</p> <p>Internal cortex—The cortex is mainly composed of parallel-fibered bone, vascularized by few scattered simple primary vascular canals and primary osteons. Most of the fibres in the bone matrix are transversely sectioned; however, a few well delineated, transversely sectioned fibre bundles are visible as well (Fig. 6d).</p></div> 	https://treatment.plazi.org/id/03F1333EFFF4FFDEFC83BA9F4879FDA3	Public Domain	No known copyright restrictions apply.
