Stubbs et al. Biomechanical analysis - Raw biomehanical character data

This file contains the raw data from 14 biomechanical measurements, taken from the mandibles of 107 Mesozoic crurotarsans. To produce a biomechanical morphospace the data should be z-transformed and entered into PAST. Using the PCO (principle coordinates) function and the Gower similarity index will produce a biomechanical mandibular morphospace. Abbreviations for characters: Total mandibular length (TOTL), Quadrate/articular offset (QUADOFF), Relative length of the mandibular symphysis (SYMPH), Relative length of dental row (%DENT), Relative area of the fenestrae (%FEN), Anterior mechanical advantage (AMA), Posterior Mechanical Advantage (PMA), Opening mechanical advantage (OMA), Maximum Second Moment of Area (MAXI), Average Second Moment of Area (AVRI), Max polar moment of inertia (MAXJ), Average polar moment of inertia (AVRJ), Slenderness of the largest tooth (CUSPMAX), The curvature of largest tooth (CURVEMAX). Full descriptions of each character can be found in the electronic supplementary material accompanying the main article.

本文件包含了取自107件中生代鳄形超类（Crurotarsi）下颌骨的14项生物力学测量原始数据。若需构建生物力学形态空间，需先对数据执行Z变换（z-transform），再导入PAST软件。借助主坐标分析（Principal Coordinates, PCO）功能与高韦尔（Gower）相似性指数，即可生成下颌骨生物力学形态空间。各测量性状的缩写说明如下：下颌骨总长度（TOTL）、方骨/关节突偏移量（QUADOFF）、下颌联合相对长度（SYMPH）、齿列相对长度（%DENT）、下颌窗相对面积（%FEN）、前部机械优势（AMA）、后部机械优势（PMA）、开口机械优势（OMA）、最大截面二次矩（MAXI）、平均截面二次矩（AVRI）、最大极惯性矩（MAXJ）、平均极惯性矩（AVRJ）、最大牙齿细长比（CUSPMAX）、最大牙齿曲率（CURVEMAX）。各测量性状的详细描述可参见主论文附带的电子补充材料。
