Abstract

Several skulls of the ornithischian dinosaur Lesothosaurus diagnosticus (Lower Jurassic, southern Africa) are known, but all are either incomplete, deformed, or incompletely prepared. This has hampered attempts to provide a comprehensive description of skull osteology in this crucial early dinosaurian taxon. Using visualization software, computed tomographic scans of the Lesothosaurus syntypes were digitally segmented to remove matrix, and identify and separate individual cranial and mandibular bones, revealing new anatomical details such as sutural morphology and the presence of several previously undescribed elements. Together with visual inspection of exposed skull bones, these CT data enable a complete description of skull anatomy in this taxon. Comparisons with our new data suggest that two specimens previously identified as Lesothosaurus sp. (MNHN LES 17 and MNHN LES 18) probably represent additional individuals of Lesothosaurus diagnosticus.

摘要

人们已知几种鸟脚亚目恐龙莱索托龙（生活在南非下侏罗纪）的头骨，但所有头骨要么不完整、变形，要么清理不彻底。这阻碍了人们对这个关键的早期恐龙类群的头骨骨骼学进行全面描述。利用可视化软件，对莱索托龙模式标本的计算机断层扫描数据进行数字分割，以去除基质，并识别和分离单个颅骨和下颌骨，从而揭示了新的解剖学细节，如缝合形态以及几个先前未描述的骨骼的存在。结合对暴露的头骨骨骼的目视检查，这些CT数据能够完整描述该类群的头骨解剖结构。与我们的新数据进行比较表明，之前被鉴定为莱索托龙属（MNHN LES 17和MNHN LES 18）的两个标本可能代表莱索托龙的其他个体。
