Fig. 40. Transverse histological sections of Balaur. (A) Left fibula of the B. bondoc holotype (EME PV.313) shown in polarized microscopy. Dense Haversian remodeling (Hc 5 Havesian canals), endosteal bone (eb), and weakly differentiated lines of arrested growth (LAGs) are evident (arrows). Note that deep cortical lines do not follow the prominent contours of the periosteal surface sculpturing (ss). Scale bar 5 500 um. (B) Transverse histological section of the B. sp. left ulna (LPB [FGGUB R.1581] shown in polarized microscopy. Dense Haversian remodeling (Hc 5 Haversian canals), and weakly differentiated lines of arrested growth (LAGs) are evident (arrows). Note that deep cortical lines do not follow the prominent contours of the periosteal surface sculpturing (ss). Scale bar 5 500 um. (C) Transverse histological section of the B. sp. left ulna in polarized microscopy, showing locally preserved deep cortical primary matrix. The periosteal surface is to the right (not shown). Weakly expressed deep cortical fibrolamellar bone with circumferential vascularization (cv) is preserved. Scale bar 5 200 um. (D) Closeup histological section of the B. sp. left ulna showing periosteal surface sculpturing and corresponding lines of arrested growth. Note that the LAGs shown here that were deposited latest in life (arrows) follow the contours of the periosteal surface sculpturing (ss), suggesting that the sculpturing is not a diagnetic or taphonomic feature. Scale bar 5 200 um.
