中国古生物志甘肃临夏盆地晚中新世副竹鼠类（2018）

本书对在甘肃临夏回族自治州内发现的副竹鼠类进行了详细研究，共记述了两个属[ 副竹鼠属（Pararhizomys）和假竹鼠新属（Pseudorhizomys gen. nov.）] 的7 个种。其中包括1 个已知种[ 三趾马层副竹鼠（Pararhizomys hipparionum）]，2 个新种（Pa.huaxiaensis, Pa. longensis）和4 个新属、新种（Ps. indigenus, Ps. gansuensis, Ps. planus,Ps. pristinus）。书中对副竹鼠类各属、种的头骨和颅后骨骼进行了详细描述、对比；运用分支系统学分析，将副竹鼠类归入鼠超科中盲鼹鼠科（Spalacidae）的拟速掘鼠亚科（Tachyoryctoidinae），并为副竹鼠类创建了一个新族——副竹鼠族（Pararhizomyini）。书中对假竹鼠和副竹鼠的头部和前肢部分肌肉作了复原和肌能分析，讨论了它们的生活习性，认为副竹鼠类为穴居的啮齿类。副竹鼠族的起源、演化发展和绝灭与晚中新世—早上新世时东亚中部的地理和气候环境的变化有关，特别与青藏高原隆升有密切关系。

This book presents a comprehensive study of the Pararhizomyine rodents discovered in Linxia Hui Autonomous Prefecture, Gansu Province, China. A total of 7 species under two genera, *Pararhizomys* and *Pseudorhizomys gen. nov.*, are documented herein. Among these, there is 1 known species (*Pararhizomys hipparionum*), 2 new species belonging to *Pararhizomys* (*Pa. huaxiaensis*, *Pa. longensis*), and 4 new species assigned to the newly established *Pseudorhizomys* (*Ps. indigenus*, *Ps. gansuensis*, *Ps. planus*, *Ps. pristinus*). The book provides detailed descriptions and comparative analyses of the cranial and postcranial skeletons of all genera and species within the Pararhizomyine rodents. Using cladistic analysis, this study assigns the Pararhizomyine rodents to the subfamily Tachyoryctoidinae of the family Spalacidae within the superfamily Muroidea, and establishes a new tribe, Pararhizomyini, for this group. Additionally, the book reconstructs and conducts functional analyses of the cephalic and forelimb musculature of both *Pseudorhizomys* and *Pararhizomys*, discusses their inferred life habits, and concludes that the Pararhizomyine rodents are fossorial rodents. The origin, evolutionary development, and extinction of the tribe Pararhizomyini are closely correlated with the geographic and climatic changes in central East Asia during the Late Miocene to Early Pliocene, particularly the uplift of the Qinghai-Tibet Plateau.

背景概述

该数据集基于2018年在甘肃临夏盆地发现的副竹鼠类化石研究，系统记述了两个属的7个种，包括新属和新种，并运用分支系统学分析将其归入盲鼹鼠科的拟速掘鼠亚科，创建了新族。研究揭示了副竹鼠类为穴居啮齿类，其起源和演化与晚中新世—早上新世的地理气候环境变化及青藏高原隆升密切相关。
