Craniodental morphology and phylogeny of marsupials

The current literature on marsupial phylogenetics includes numerous studies based on analyses of morphological data with limited sampling of Recent and fossil taxa and many studies based on analyses of molecular data with dense sampling of Recent taxa, but few studies have combined both data types. Another dichotomy in the marsupial phylogenetic literature is between studies focused on New World taxa, and those focused on Sahulian taxa. To date, there has been no attempt to assess the phylogenetic relationships of the global marsupial fauna based on combined analyses of morphology and molecular sequences for a dense sampling of Recent and fossil taxa. For this report, we compiled morphological and molecular data from an unprecedented number of Recent and fossil marsupials. Our morphological data consist of 180 craniodental characters that we scored for 97 terminals representing every currently recognized Recent genus, 42 additional ingroup (crown-clade marsupial) terminals represented b..., ,

当前有袋类系统发育学（marsupial phylogenetics）领域的相关文献中，存在大量基于形态学数据开展分析的研究——此类研究对现生与化石类群的采样规模有限；同时也有诸多基于分子数据的研究，此类研究对现生类群实现了密集采样，但极少有研究同时整合这两类数据。有袋类系统发育研究还存在另一分野：一类研究聚焦于新大陆类群，另一类则专注于萨胡尔（Sahulian）类群。截至目前，尚无研究通过整合形态学与分子序列数据，对涵盖大量现生及化石类群的全球有袋类动物区系开展系统发育关系分析。本报告中，我们从前所未有的大量现生及化石有袋类样本中整合了形态学与分子数据。我们的形态学数据包含180个颅齿特征，为涵盖当前所有已确认现生有袋类属的97个终端分类单元完成了性状评分；另有42个额外的内群（冠群有袋类，crown-clade marsupial）终端分类单元相关信息由……
