封面说明:临河盗龙头骨照片和复原图。精美临河盗龙是一种发现于内蒙古西部的驰龙类恐龙。其正型标本是已知唯一的标本,是世界上产自上白垩统最精美的驰龙类标本之一。与其他驰龙类的对比显示,精美临河盗龙具有许多其他驰龙类属种的自近裔性状,指示在驰龙类中存在着一个非常复杂的特征分布情况。许多新发现的细微形态变异对于未来精细的系统发育分析具有重要意义。详见本期徐星等人文。(绘图:韩江雨)
Cover image: Photograph and reconstruction of Linheraptor exquisitus skull and mandible. L. exquisitus is a dromaeosaurid dinosaur from the Late Cretaceous of western Nei Mongol, China. The holotype, the only known specimen, is one of the most beautifully preserved dromaeosaurid specimens recovered from the Upper Cretaceous worldwide. Comparison with other dromaeosaurids indicates that L. exquisitus possesses features that were previously identified as autapomorphies of various other dromaeosaurids and points to an unexpectedly complex distribution of derived osteological features amongst dromaeosaurids. Many of the newly recognized subtle morphological variations are potentially of great importance for fine-scale phylogenetic analyses. See details in the paper of Xu et al. (Illustrated by HAN Jiang-Yu)
