Abstract

ABSTRACT Selected fruits and seeds preserved as molds and casts in sediments from the Anjou flora of Maine-et-Loire have been reexamined with the aid of X-ray tomography. Virtual casts and surface renderings from micro-CT scanning data reveal external and internal morphological characters that were not visible by standard reflected light microscopy. Application of this methodology leads to a revision of the fruit formerly treated as Juglandicarya. It is a 5-valved capsule of likely sapindalean affinity, and is placed in Vaudoisia gruetii (Vaudois-Miéja) gen. et. comb. nov. A seed with the characteristic rumination of Anonaspermum is also recognized for the first time, as are capsular fruits of Ericaceae. We note that many disseminules are hidden from optical viewing because they are buried within the hand samples. A more extensive micro-CT scan investigation of more samples, including those showing only fossil leaf impressions at the surface, may be expected to yield a wealth of new information on this classic flora.

对法国西部安茹始新世植物群的修正，用x射线断层摄影的新数据

摘要:我们用x射线断层扫描技术重新研究了以霉菌和铸件形式保存在卢瓦尔省安茹植物群沉积物中的水果和种子。来自微ct扫描数据的虚拟模型和表面渲染显示了标准反射光显微镜不可见的外部和内部形态特征。这种方法的应用导致了对以前被视为Juglandicarya的水果的修订。它是一个5瓣的蒴果，可能与无果有亲缘关系，被放置在Vaudoisia gruetii (vaudois - misamuja) genet . comb.中。11 .具有反刍特征的种子也首次被发现，Ericaceae的荚果也首次被发现。我们注意到，许多弥散体隐藏在光学观察之外，因为它们被埋在手样中。对更多样本进行更广泛的微型ct扫描调查，包括那些只在表面显示化石叶子印痕的样本，可能会产生关于这种经典植物群的丰富新信息。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
