| 摘 要： | 1923年Nopcsa命名的Emydichnium是龟类足迹最早的报道，后来其他一些中生代的足迹也被陆续报道描述。但是大多数化石只显示出或多或少的明显爪印或者划痕，无法反映造迹者足部较为全面的生物学特征。山东诸城皇龙沟足迹点保存了早白垩世大量形态多样的龟类足迹，本文对其中一保存较好，能够反映足部生物学特征的龟类足迹进行了详细描述，并依据数据统计与莱阳足迹Liayangpus进行对比，显示两者存在明显不同。诸城的龟类足迹区别于以往发现的龟类足迹，因此根据其形态建立新种：完整诸城足迹Zhuchengichnites perfectus。本文亦对中国发现的龟类足迹化石点的层位、保存类型等进行了总结。

| Abstract: | Emydichnium named by Nopcsa in 1923 was the earliest scientific report of turtle footprints. Later, some Mesozoic turtle footprints were also reported and described one after another. However, many fossils only show more or less obvious claw prints or scratches, and some claw prints are connected by an arched structure. These preservation conditions can not reflect the more comprehensive biological characteristics of the maker''s feet. Huanglonggou footprint site in Zhucheng, Shandong Province has preserved a large number of turtle footprints with various forms in the Early Cretaceous. This paper describes in detail one of the well preserved turtle footprints that can reflect the biological characteristics of the feet, and compares it with the Laiyang footprints, Liayangpus, according to data statistics. It shows that there are obvious differences between the two. The turtle footprints in Zhucheng are different from those found in other places in the past, Therefore, according to its morphology, a new turtle track taxon, Zhuchengichnites perfectus is established. This paper also summarizes the horizons and preservation types of turtle footprint fossil sites found in China. |
