Mario Bronzati got his bachelor's (2009) and master's (2012) degrees from the University of São Paulo, Brazil. He moved to Germany in 2013 for a PhD in the Ludwig-Maximilians-University in Munich, conducting his research in the Bavarian State Collection for Palaeontology. The main topic of his PhD research is the evolution of the braincase anatomy in sauropodomorph dinosaurs. He is also interested in the early evolution of dinosaurs and in the evolution of Crocodyliformes.

 

FIGURE 1. Simplified cladogram showing the relationships of the three main lineages of dinosaurs with focus on Sauropodomorpha. Letters A - F are related to clades treated in the main text. The assumed ages for the taxa of the tree are represented by rectangles thicker than other branches. Cladogenetic events (dichotomies) are not calibrated against geological time. Ornithischia is represented by the following taxa: Pisanosaurus, Heterodontosauridae, Eocursor, Thyreophora, Neornithischia. Theropoda is represented by the following taxa: Tawa, coelophysoids, Ceratosauria, Tetanurae. All other taxa represent Sauropodomorpha (here following the definition of Galton and Upchurch, 2004). Sauropoda (here following the definition of Salgado et al., 1997) is represented by Vulcanodon, Tazoudasaurus, Spinophorosaurus, Neosauropoda.

FIGURE 2. Simplified version of the cladogram of Figure 1 showing the relationships of the three main lineages of dinosaurs with focus on Sauropodomorpha. ‘Sauropodomorpha A’ and ‘Sauropodomorpha B’ represent two hypothetical taxa that are more closely related to Saturnalia than to Sauropoda. Ornithischia is represented by a single terminal taxon and Theropoda is represented by the living bird Gallus gallus.

FIGURE 2. Research articles published in Palaeontologia Electronica for each year (2017 exclusive), expressed as a percentage of each article category. Over the years PE has published research articles in a number of sub-categories: a Critical Review category was used briefly, Technical Articles have been differentiated from Research Articles since 2009, and the Fossil Calibration Articles were introduced in 2015. However, for consistency and in order to examine our 20 year trends, I have gone back through all research articles and retroactively assigned each to one of five categories: Research, Technical, Taxonomic, Review/Atlas/Guide, and Fossil Calibration.

FIGURE 3. Research articles published in Palaeontologia Electronica for each year (2017 exclusive), expressed as a percentage of each palaeontological sub-discipline. This represents a somewhat more arbitrary (compared to Figure 2) assignment of each research article to one of 11 palaeontological sub-disciplines. This assignment is more arbitrary because many articles aren’t easily categorised into a single sub-discipline and, depending on subject matter, the sub-disciplines themselves can overlap. Other articles, particularly highly technical articles, don’t always fit so neatly within any strictly palaeontological sub-discipline. Nevertheless, primarily on the basis of article title, with reference to the abstract and keywords where necessary, each article has been assigned as Museum/Education, Micropalaeontology, Palaeobotany, Palynology, Invertebrate Palaeontology, Vertebrate Palaeontology, Taphonomy, Ichnology, Palaeoecology, Epistemology/Philosophy, and Stratigraphy/Geology.

Alycia Stigall is Professor of Paleontology at Ohio University. Her research focuses on exploring the relationship between speciation, biogeographic distribution, and ecological factors using Ordovician rhynchonelliform brachiopods as model taxa. She and her students examine the how species immigration events, including the Richmondian Invasion and Late Devonian Biodiversity Crisis, contribute to changes in biodiversity patterns in the history of life. The Stigall lab uses a variety of methods including ecological niche modeling, phylogenetic analysis, GIS analyses, and field work to investigate these patterns. The Ordovician Atlas project is a natural extension of this work. To date, over a dozen undergraduate and six graduate students have been involved in the creation of the Ordovician Atlas and its related outreach and digitization activities in the Stigall Lab.

Bruce S. Lieberman is an invertebrate paleontologist who researches macroevolutionary pattern and process. He is a Professor in the Department of Ecology & Evolutionary Biology and a Senior Curator in the Biodiversity Institute at the University of Kansas. He received his A.B. at Harvard College, where he was advised by Stephen Jay Gould, and his Ph.D. at Columbia University in New York City, where he was advised by Niles Eldredge. He also did post-doctoral fellowships at Yale University and Harvard, where he worked with Elisabeth Vrba and Andy Knoll, respectively. He is especially interested in macroevolutionary theory and biogeography, as well as in applying phylogenetics, Geographic Information Systems, Ecological Niche Modeling and other quantitative techniques to the study of key episodes in the history of life, and to deduce the role that abiotic and biotic factors play in motivating evolution.
