Abstract

Fossil capitate hydrozoans require exceptional conditions for preservation. Here we describe Bertratis ciurcae new genus, new species from the Silurian (Pridoli) of southern Ontario and upper New York State, where it occurs in association with a diverse assemblage of eurypterids. Only the float (pneumatophore) is well preserved, surviving as a thick carbonaceous compression. The new taxon is the largest fossil capitate reported, reaching a width of 17 cm, and the third Porpita-like example known from the Paleozoic. It was a rare pelagic component of the biota of the well-known Bertie Group Lagerstätten. UUID: http://zoobank.org/1eb789e3-67b4-4e46-9baf-6320d4b67d6c

头状水螅动物化石需要特殊的保存条件。在这里，我们描述了Bertratis ciurcae新属，新种，来自安大略省南部和纽约州北部志留系(Pridoli)，在那里它与各种各样的eurypterids组合在一起。只有浮子(气团)保存完好，以厚厚的碳质压缩形式存活下来。这个新分类群是报道过的最大的头状化石，宽度达到17厘米，也是古生代已知的第三个类似porpita的例子。这是著名的伯蒂群Lagerstätten生物群中罕见的远洋生物。UUID: http://zoobank.org/1eb789e3 - 67 - b4 - 4 - e46 - 9 - baf - 6320 d4b67d6c

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.
