摘要/Abstract

摘要： 利用酸处理、高精度计算机断层扫描(CT)、三维重建、扫描电镜(SEM)拍照和古组织学切片等多种方法与技术,对在云南曲靖早泥盆世西屯组中发现的软骨鱼类—雅致郭氏鱼(Gualepis elegans)鳞片进行详细的形态学与组织学研究.研究结果表明,雅致郭氏鱼的鳞片根据其形态学特征可分为六种类型,并划分出雅致郭氏鱼鳞片的四个生长阶段,上述工作增加了对雅致郭氏鱼的认识,进一步丰富了西屯早期脊椎动物的多样性,并为早期软骨鱼类的演化和系统发育提供重要数据支持.

Abstract: Detailed morphological and histological studies of the scales of Gualepis elegans,chondrichthyan,from the Xitun Formation Early Devonian of Qujing were conducted.Various methods and techniques such as high resolution Computed Tomography,Three-dimensional Reconstruction,Scanning Electron microscopy and histology thin sections were used to systematically and comprehensively analyze the scales of the Gualepis elegans.According to the morphological characteristics of the scales,the scales of the Gualepis elegans were divided into six morphotypes that were described and compared in detail.By comparing the morphology and histology of numerous scales in different growth stages,the four growth stages of the Gualepis elegans scales were divided.In this work,the classification and detailed study of the scale morphotypes of the Gualepis elegans and the determination of their growth pattern increase our understanding of Gualepis elegans and provide significant data for the evolution and phylogeny of early chondrichthyans.

Key words: Qujing, Lower Devonian, Gualepis elegans, morphology, histology
