DeMar et al._ESM file S1

This file contains supplementary text and 14 supplementary figures. The supplementary text provides (i) supplementary morphological descriptions; (ii) methodology on estimating squamate body-sizes; (iii) interpretations of the palaeoenvironmental setting of Magnuviator ovimonsensis and other relevant fossil iguanomorphs; (iv) new systematic interpretations of Late Cretaceous lizards previously assigned to Pleurodonta; (v) cladistic analysis methodologies and results; (vi) character scorings of Magnuviator ovimonsensis and Pariguana lancensis; (vii) information regarding CT and µCT scans; and (viii) a complete strict consensus tree and apomorphy list derived from our morphology-based cladistic analysis. The supplementary figures show additional specimen images, cladograms, and comparative body-size estimates of fossil and extant lizards. The text provides background information for interpretations made in the manuscript.

本文件包含补充文本与14幅补充插图。该补充文本涵盖以下八项内容：(i) 补充形态学描述；(ii) 有鳞目（squamate）体型估算方法；(iii) 针对Magnuviator ovimonsensis及其他相关化石鬣蜥形类（iguanomorph）的古环境背景解读；(iv) 对此前被划归侧齿类（Pleurodonta）的晚白垩世蜥蜴的全新系统学解读；(v) 分支系统学分析方法与结果；(vi) Magnuviator ovimonsensis与Pariguana lancensis的性状编码信息；(vii) 计算机断层扫描（CT）及显微计算机断层扫描（µCT）相关细节；(viii) 基于形态学分支系统学分析得到的完整严格合意树与衍征列表。补充插图则展示了额外的标本图像、分支谱系图，以及化石与现生蜥蜴的体型估算对比结果。本补充文本为论文正文中的相关解读提供了背景支撑信息。
