Palaeoworld

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

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
