摘要

木材Araucarioxylon australe cri出版于1889年。尽管涉及许多命名和分类学问题，但它从未被修订。我们在法国雷恩大学的古生物收藏中发现了模式材料。对模式进行了描述和说明，并指定了一个选型。标题平梭梭（Planoxylon Stopes）一新种，P. toitoii n.sp。是认可的。一种类似的木材，Planoxylon hectorii Stopes也经过修订。讨论了扶桑（Mixoxylon Chernomorets et Sakala）与扶桑（Planoxylon Stopes）的分类学关系，并提出了扶桑的种键。这种新的分类框架使得冈瓦纳高古纬度中生代木材化石记录的古生物地理图像更加清晰。

Almost forgotten fossil wood points to the existence of an overlooked group of Mesozoic Gondwanan gymnosperms

The wood Araucarioxylon australe Crié was published in 1889. Despite the many nomenclatural and taxonomic issues involved, it has never been revised. We found type material in Rennes University (France) palaeontological collection. Syntypes are described and illustrated, and a lectotype is designated. A new species of Planoxylon Stopes, P. toitoii n.sp. is recognised. A similar wood, Planoxylon hectorii Stopes is also revised. Taxonomical relationship between Mixoxylon Chernomorets et Sakala and Planoxylon Stopes are discussed and a key to Planoxylon species proposed. This renewed taxonomical framework allows a clearer palaeobiogeographical image to emerge from Gondwana high-palaeolatitude Mesozoic fossil wood-record.

期刊介绍： The Review of Palaeobotany and Palynology is an international journal for articles in all fields of palaeobotany and palynology dealing with all groups, ranging from marine palynomorphs to higher land plants. Original contributions and comprehensive review papers should appeal to an international audience. Typical topics include but are not restricted to systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, taphonomy, palaeoenvironmental reconstructions, vegetation history, and practical applications of palaeobotany and palynology, e.g. in coal and petroleum geology and archaeology. The journal especially encourages the publication of articles in which palaeobotany and palynology are applied for solving fundamental geological and biological problems as well as innovative and interdisciplinary approaches.
