Abstract

Abstract: Ooimmuration is here defined as a taphonomic process by which fossils are preserved within ooids. It is a form of lithoimmuration, although depending on the role of microbes in the formation of the ooid cortex, ooimmuration can also be considered a type of bioimmuration. Fossils enclosed within ooids are protected from bioerosion as well as the abrasion common in energetic depositional environments such as ooid shoals. Many taxa in some fossil assemblages may be known only because they were ooimmured. We describe as examples of ooimmuration fossils preserved in an oolite from the Middle Jurassic (Bajocian) Carmel Formation in southwestern Utah.

卵子免疫：利用卵子增强化石保存，以美国犹他州西南部中侏罗世为例

摘要:卵固化在这里被定义为化石在卵内保存的埋藏学过程。这是一种岩石免疫，尽管取决于微生物在卵皮质形成中的作用，卵免疫也可以被认为是一种生物免疫。封闭在流体中的化石免受生物侵蚀，以及在含能沉积环境(如鲕滩)中常见的磨损。某些化石组合中的许多分类群可能只是因为它们是免疫的而为人所知。我们描述了保存在犹他州西南部中侏罗统卡梅尔组(Bajocian Carmel组)鲕粒中的卵化化石的例子。

期刊介绍： PALAIOS is a monthly journal, founded in 1986, dedicated to emphasizing the impact of life on Earth''s history as recorded in the paleontological and sedimentological records. PALAIOS disseminates information to an international spectrum of geologists and biologists interested in a broad range of topics, including, but not limited to, biogeochemistry, ichnology, paleoclimatology, paleoecology, paleoceanography, sedimentology, stratigraphy, geomicrobiology, paleobiogeochemistry, and astrobiology. PALAIOS publishes original papers that emphasize using paleontology to answer important geological and biological questions that further our understanding of Earth history. Accordingly, manuscripts whose subject matter and conclusions have broader geologic implications are much more likely to be selected for publication. Given that the purpose of PALAIOS is to generate enthusiasm for paleontology among a broad spectrum of readers, the editors request the following: titles that generate immediate interest; abstracts that emphasize important conclusions; illustrations of professional caliber used in place of words; and lively, yet scholarly, text.
