Figure 1 in A new basal ornithopod dinosaur (Frenchman Formation, Saskatchewan, Canada), and implications for late Maastrichtian ornithischian diversity in North America
Figure 1. Diagrams of the skeletons of relatively complete articulated Thescelosaurus specimens (A–I) and Parksosaurus (J), showing their comparative size and degree of completeness. Bones present in each specimen are represented in white. A, LACM 33542; B, SDSM 7210; C, MOR 979; D, NCSM 15728; E, USNM 7757; F, USNM 7758; G, CMN 8537; H, LACM 33543; I, RSM P 1225.1; J, ROM 804. Skeletons are scaled isometrically based on femur and tibia length, when available. Skeletons lacking both tibiae and femora were scaled using the following elements: anteroposterior thickness of orbit for SDSM 7210; length of the dentary for LACM 33543; and length of the humerus for USNM 7758. Proportions for specimens of Thescelosaurus represent those of USNM 7757, and do not illustrate proportional changes that would be evident because of allometric scaling. Scale equals 1 m. Modified from Boyd et al. 2009.

Body size and geographic distribution of foraminiferal specimens during the Frasnian-Famennian (Frasnian), Guadalupian-Lopingian (Capitanian), Permian-Triassic (Changhsingian), Triassic-Jurassic (Rhaetian), and Cretaceous-Paleogene (Maastrichtian) mass extinctions.
<p>This dataset is about body size and geographic distribution of foraminiferal specimens during the Frasnian-Famennian (Frasnian), Guadalupian-Lopingian (Capitanian), Permian-Triassic (Changhsingian), Triassic-Jurassic (Rhaetian), and Cretaceous-Paleogene (Maastrichtian) mass extinctions.</p> <p>Foraminiferal body size data collection</p> <p>First, we collected published papers with foraminiferal images from the Frasnian (382.7-372.2 Ma), Capitanian (264.28-259.51 Ma), Changhsingian (254.14-251.902 Ma), Rhaetian (208.5-201.3 Ma), and Maastrichtian (72.1-66.1 Ma). Second, we measured two primary axes of specimens, such as maximum length and height in a conical or cylindrical shell. For some specimens, where there is no way to measure the length of both axes, we calculate the length of the unknown axis based on the aspect ratio of the type species. Third, we used the test volume as a standard indicator of body size, taking into account the diversity of foraminiferal morphology. Finally, the test volumes were calculated on a logarithmic scale with base 10 due to large individual differences, and the specific calculation is shown in Feng et al. (2020).</p>
