Fig. 1 in Bone microstructure and relative age of the holotype specimen of the diplodocoid sauropod dinosaur Suuwassea emilieae
Fig. 1. The right tibia of the holotype (ANS 21122) of the diplodocoid sauropod Suuwassea emilieae Harris and Dodson, 2004, Morrison Formation, Late Jurassic. For ease of sectioning, the tibia was dismantled at a natural break and then sectioned 3 cm from the preserved distal end (red line) to ensure a complete cross section. The proximal end of the distal segment was then re-attached to the proximal segment.
Fig. 6 in Constraints on the lamina density of laminar bone architecture of large-bodied dinosaurs and mammals
Fig. 6. Lamina density vs. femur length of sauropodomorph dinosaur taxa (Plateosaurus and neosauropods). Among the neosauropods, lamina density does not correlate with femur length, although a slight decrease may take place with increasing femur length (Slope = -0.001; Intercept = 5.61; Pearson's R = -0.372, two-tailed p = 0.052). High variability of lamina density in Plateosaurus may be related to its developmental plasticity (cf. Sander and Klein 2005).
Fig. 3 in Bone microstructure and relative age of the holotype specimen of the diplodocoid sauropod dinosaur Suuwassea emilieae
Fig. 3. Histologic structures visible in the tibia of the holotype (ANS 21122) of the diplodocoid sauropod Suuwassea emilieae Harris and Dodson, 2004, Morrison Formation, Late Jurassic, photographed under plane-polarized light. A. Successive growth cycles in the caudolateral region of the bone. Brackets indicate successive highly and poorly vascularized zones. Highly vascularized zone with dense primary osteons (right), followed by a poorly vascularized annulus (middle). The leftmost region shows the subsequent zone characterized by higher vascularization (outermost cortex to left). B. The high density of secondary osteons (outlined in green) in the medial inner cortex, showing overprinting by a second generation (green arrow). Additionally, primary osteons are visible between secondary osteons showing that the bone is not completely remodeled (blue arrow). C. A cluster of secondary osteons in the outer cortex of the craniomedial region. This cluster is surrounded by primary osteons. D. Outer cortex of the caudolateral region, showing the LAG (line of arrested growth) (arrow) associated with the fourth annulus. E. Two LAGs in the outermost cortex of the lateral region. F. Primary osteons in the outermost cortex of the craniolateral region leading up to the periosteal surface of the bone.
Fig. 5 in Constraints on the lamina density of laminar bone architecture of large-bodied dinosaurs and mammals
Fig. 5. Comparison of dinosaur and mammal lamina density. A test for normality of the combined distributions failed (which is common for large datasets), but descriptive statistics suggest the dataset may still be normal (skew [lopsidedness] = 0.449; kurtosis [peakedness or flatness] = -0.107). Mean mammal lamina density differs significantly from mean dinosaur lamina density (independent t-test, t = 5.928; p <0.001). A non-parametric alternative suggests an equally significant difference between the medians (Mann-Whitney U statistic = 752.0; two-tailed p value <0.001). For discussion of these results, please refer to the main text.
Fig. 4 in Constraints on the lamina density of laminar bone architecture of large-bodied dinosaurs and mammals
Fig. 4. Comparison of the frequency distributions of lamina density of the different mammal groups. These data represent 24 of our own samples complemented with 15 elephantid samples from Curtin et al. (2012). Mammal lamina density follows a normal distribution. Descriptive statistics of mammal lamina density: mean = 4.154 laminae/mm; SD = 1.517 laminae/ mm; skew = 0.964 and kurtosis = 0.289. For further discussion please refer to the main text.
Fig. 3 in Constraints on the lamina density of laminar bone architecture of large-bodied dinosaurs and mammals
Fig. 3. Comparison of the frequency distributions of lamina density of sauropodomorph dinosaur taxa. The distribution follows a normal distribution. Descriptive statistics for sauropod lamina density: mean = 5.76 laminae/mm; SD = 1.386 laminae/mm; skew = 0.842; kurtosis = 0.021. For further discussion please refer to the main text.
