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. 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.
Fig. 2 in Constraints on the lamina density of laminar bone architecture of large-bodied dinosaurs and mammals
Fig. 2. Laminar bone tissue in a Brachiosaurus humerus (MFN t7). One lamina is defined as the distance from the center of a vascular canal to the center of the following vascular canal, as indicated by the arrows (cf. Sander and Tückmantel 2003).
Fig. 1. Static and dynamic osteogenesis. A in Constraints on the lamina density of laminar bone architecture of large-bodied dinosaurs and mammals
Fig. 1. Static and dynamic osteogenesis. A. Static osteogenesis by static osteoblasts proliferating in situ from mesenchymal tissue. The random orientation of the osteoblasts creates a random local fibre orientation of the produced matrix. B. Static osteoblasts turn into static osteocytes as they become entrapped in the mineralizing woven bone matrix. C. Dynamic osteoblasts arrange themselves on the woven bone and start producing highly organized primary bone, occasionally trapping a dynamic osteoblast, which will then become a dynamic osteocyte. D. Static and dynamic osteocyte lacunae in a longitudinal section of a humerus of the titanosaur Alamosaurus. A–C modified from Marotti (2010), D modified from Stein and Prondvai (2014).

Fig.10. A. BMNH M 45658, an I2 tentatively referred to Loxaulax valdensis from the Early Cretaceous Hastings Beds Group, mainland Britain, in occlusal (A1) and distal (A2) views, line drawing (A3) to show features giving the erroneous impression that BMNH M 45658 may be a left I3. See text for a discussion. B. BMNH M 45483 a left I3 assigned to Eobaatar clemensi from the Early Cretaceous Wessex Formation, Isle of Wight, in occlusal (B1) and anterolabial (B2) views, line drawing (B3) as seen in B2. C. Normal light photograph of an indeterminate plagiaulacoid left I2 (part of SMNS 51981) from the Early Cretaceous Wessex Formation, Isle of Wight, in labial view (it was not possible to obtain scanning electron micrographs of the specimen which was glued to card by the original collector).
