摘要

由于虾类的快速分解，很难将其保存在化石记录中。在这项研究中，我们对巴西东北部 Araripe 盆地下白垩世 Romualdo 地层的虾类分类学有了新的认识。我们对其进行了全面的分类审查，包括对主模式和其他化石材料进行了更细致的制备，从而揭示了以前未知的解剖学特征，再次确认了其在帕拉伊蒙科中的分类。

New data and redescription of Kellnerius jamacaruensis Santana et al., 2013, a Palaemonidae shrimp from the Araripe Basin in northeastern Brazil

The preservation of shrimp in the fossil record is difficult due to their rapid decomposition. In this study, we provide new taxonomic insights into from the Lower Cretaceous Romualdo Formation in the Araripe Basin, northeastern Brazil. A comprehensive taxonomic review, including a more meticulous preparation of the holotype and additional fossil material, enabled the disclosure of previously unknown anatomical features, reaffirming its classification within the family Palaemonidae.

期刊介绍： Palaeoworld is a peer-reviewed quarterly journal dedicated to the study of past life and its environment. We encourage submission of original manuscripts on all aspects of palaeontology and stratigraphy, comparisons of regional and global data in time and space, and results generated by interdisciplinary investigations in related fields. Some issues will be devoted entirely to a special theme whereas others will be composed of contributed articles. Palaeoworld is dedicated to serving a broad spectrum of geoscientists and palaeobiologists as well as serving as a resource for students in fields as diverse as palaeobiology, evolutionary biology, taxonomy and phylogeny, geobiology, historical geology, and palaeoenvironment. Palaeoworld publishes original articles in the following areas: •Phylogeny and taxonomic studies of all fossil groups •Biostratigraphy, chemostratigraphy, chronostratigraphy •Palaeoecology, palaeoenvironment and global changes throughout Earth history •Tempo and mode of biological evolution •Biological events in Earth history (e.g., extinctions, radiations) •Ecosystem evolution •Geobiology and molecular palaeobiology •Palaeontological and stratigraphic methods •Interdisciplinary studies focusing on fossils and strata
