Taxonomy, morphology, masticatory function and phylogeny of heterodontosaurid dinosaurs  [cached]
Paul Sereno
ZooKeys , 2012, DOI: 10.3897/zookeys.226.2840
Abstract: Heterodontosaurids comprise an important early radiation of small-bodied herbivores that persisted for approximately 100 My from Late Triassic to Early Cretaceous time. Review of available fossils unequivocally establishes Echinodon as a very small-bodied, late-surviving northern heterodontosaurid similar to the other northern genera Fruitadens and Tianyulong. Tianyulong from northern China has unusual skeletal proportions, including a relatively large skull, short forelimb, and long manual digit II. The southern African heterodontosaurid genus Lycorhinus is established as valid, and a new taxon from the same formation is named Pegomastax africanus gen. n., sp. n. Tooth replacement and tooth-to-tooth wear is more common than previously thought among heterodontosaurids, and in Heterodontosaurus the angle of tooth-to-tooth shear is shown to increase markedly during maturation. Long-axis rotation of the lower jaw during occlusion is identified here as the most likely functional mechanism underlying marked tooth wear in mature specimens of Heterodontosaurus. Extensive tooth wear and other evidence suggests that all heterodontosaurids were predominantly or exclusively herbivores. Basal genera such as Echinodon, Fruitadens and Tianyulong with primitive, subtriangular crowns currently are known only from northern landmasses. All other genera except the enigmatic Pisanosaurus have deeper crown proportions and currently are known only from southern landmasses.

Body Size Distribution of the Dinosaurs  [PDF]
Eoin J. O’Gorman, David W. E. Hone
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0051925
Abstract: The distribution of species body size is critically important for determining resource use within a group or clade. It is widely known that non-avian dinosaurs were the largest creatures to roam the Earth. There is, however, little understanding of how maximum species body size was distributed among the dinosaurs. Do they share a similar distribution to modern day vertebrate groups in spite of their large size, or did they exhibit fundamentally different distributions due to unique evolutionary pressures and adaptations? Here, we address this question by comparing the distribution of maximum species body size for dinosaurs to an extensive set of extant and extinct vertebrate groups. We also examine the body size distribution of dinosaurs by various sub-groups, time periods and formations. We find that dinosaurs exhibit a strong skew towards larger species, in direct contrast to modern day vertebrates. This pattern is not solely an artefact of bias in the fossil record, as demonstrated by contrasting distributions in two major extinct groups and supports the hypothesis that dinosaurs exhibited a fundamentally different life history strategy to other terrestrial vertebrates. A disparity in the size distribution of the herbivorous Ornithischia and Sauropodomorpha and the largely carnivorous Theropoda suggests that this pattern may have been a product of a divergence in evolutionary strategies: herbivorous dinosaurs rapidly evolved large size to escape predation by carnivores and maximise digestive efficiency; carnivores had sufficient resources among juvenile dinosaurs and non-dinosaurian prey to achieve optimal success at smaller body size.
Publication and dissemination of datasets in taxonomy: ZooKeys working example  [cached]

ZooKeys , 2009, DOI: 10.3897/zookeys.11.210
Abstract: A concept for data publication and semantic enhancements proposed by ZooKeys and applied in the milestone paper of Miller et al. (2009) is described. For the first time in systematic zoology, an unique combination of data publication and semantic enhancements is applied within the mainstream process of journal publishing, to demonstrate how: (1) All primary biodiversity data underlying a taxonomic monograph are published as a dataset under a separate DOI within the paper; (2) The occurrence dataset is discoverable and accessible through GBIF data portal (data.gbif.org) simultaneously with the publication; (3) Occurrence dataset is published as a KML file under a distinct DOI to provide an interactive experience in Google Earth; (4) All new taxa (42) are registered at ZooBank during the publication process (mandatory for ZooKeys); (5) All new taxa (42) are provided to Encyclopedia of Life through XML mark up on the day of publication (mandatory for ZooKeys). It is proposed to clearly distinguish between static and dynamic datasets in the way they are published, preserved and cited.
Streamlining taxonomic publication: a working example with Scratchpads and ZooKeys  [cached]

ZooKeys , 2010, DOI: 10.3897/zookeys.50.539
Abstract: We describe a method to publish nomenclatural acts described in taxonomic websites (Scratchpads) that are formally registered through publication in a printed journal (ZooKeys). This method is fully compliant with the zoological nomenclatural code. Our approach supports manuscript creation (via a Scratchpad), electronic act registration (via ZooBank), online and print publication (in the journal ZooKeys) and simultaneous dissemination (ZooKeys and Scratchpads) for nomenclatorial acts including new species descriptions. The workflow supports the generation of manuscripts directly from a database and is illustrated by two sample papers published in the present issue.
Semantic tagging of and semantic enhancements to systematics papers: ZooKeys working examples  [cached]

Abstract: The concept of semantic tagging and its potential for semantic enhancements to taxonomic papers is outlined and illustrated by four exemplar papers published in the present issue of ZooKeys. The four papers were created in different ways: (i) written in Microsoft Word and submitted as non-tagged manuscript (doi: 10.3897/zookeys.50.504); (ii) generated from Scratchpads and submitted as XML-tagged manuscripts (doi: 10.3897/zookeys.50.505 and doi: 10.3897/zookeys.50.506); (iii) generated from an author’s database(doi: 10.3897/zookeys.50.485) and submitted as XML-tagged manuscript. XML tagging and semantic enhancements were implemented during the editorial process of ZooKeys using the Pensoft Mark Up Tool (PMT), specially designed for this purpose. The XML schema used was TaxPub, an extension to the Document Type Definitions (DTD) of the US National Library of Medicine Journal Archiving and Interchange Tag Suite (NLM). The following innovative methods of tagging, layout, publishing and disseminating the content were tested and implemented within the ZooKeys editorial workflow: (1) highly automated, fine-grained XML tagging based on TaxPub; (2) final XML output of the paper validated against the NLM DTD for archiving in PubMedCentral; (3) bibliographic metadata embedded in the PDF through XMP (Extensible Metadata Platform); (4) PDF uploaded after publication to the Biodiversitry Heritage Library (BHL); (5) taxon treatments supplied through XML to Plazi; (6) semantically enhanced HTML version of the paper encompassing numerous internal and external links and linkouts, such as: (i) vizualisation of main tag elements within the text (e.g., taxon names, taxon treatments, localities, etc.); (ii) internal cross-linking between paper sections, citations, references, tables, and figures; (iii) mapping of localities listed in the whole paper or within separate taxon treatments; (v) taxon names autotagged, dynamically mapped and linked through the Pensoft Taxon Profile (PTP) to large international database services and indexers such as Global Biodiversity Information Facility (GBIF), National Center for Biotechnology Information (NCBI), Barcode of Life, Encyclopedia of Life (EOL), ZooBank, Wikipedia, Wkispecies, Wikimedia, and others; (vi) GenBank accession numbers autotagged and linked to NCBI; (vii) external links of taxon names to references in PubMed, Google Scholar, Biodiversity Heritage Library and other sources. With the launching of the working example, ZooKeys becomes the first taxonomic journal to provide a complete XML-based editorial, publication and disse
