Paleontology, Cretaceous, Ecology, Extinction event and Ornithischia are his primary areas of study. His work carried out in the field of Paleontology brings together such families of science as Cartography and Archosauriformes. His Cretaceous study combines topics in areas such as Paleoecology, Mesozoic and Sauropodomorpha.
The Ecology study combines topics in areas such as Geologic record and Tetrapod. His Extinction event study combines topics from a wide range of disciplines, such as Facies and Early Triassic. His Ornithischia research is multidisciplinary, incorporating elements of Zoology, Hypsodont, Lycorhinus and Heterodontosauridae.
Richard J. Butler mostly deals with Paleontology, Ecology, Cretaceous, Taxon and Extinction event. His work in Paleontology is not limited to one particular discipline; it also encompasses Archosauriformes. His Ecology research integrates issues from Geologic record and Tetrapod.
His biological study spans a wide range of topics, including Species richness and Macroevolution. His studies deal with areas such as Autapomorphy, Clade and Cladistics as well as Taxon. The study incorporates disciplines such as Ornithopod, Anatomy and Heterodontosauridae in addition to Ornithischia.
His primary areas of study are Paleontology, Extinction event, Ecology, Evolutionary biology and Taxon. As part of his studies on Paleontology, Richard J. Butler often connects relevant areas like Sampling. His work on Erythrosuchidae as part of general Extinction event study is frequently connected to Environmental science, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.
Richard J. Butler has included themes like Mesozoic, Carboniferous rainforest collapse and Cretaceous in his Ecology study. His research investigates the link between Evolutionary biology and topics such as Range that cross with problems in Phylogenetic comparative methods, Crocodylomorpha, Fitness landscape, Crocodyliformes and Extinction. His biological study deals with issues like Pseudosuchia, which deal with fields such as Cladistics, Monophyly, Clade, Redondasaurus and Archosaur.
His main research concerns Evolutionary biology, Paleontology, Taxon, Archosauromorpha and Fossil Record. His Paleontology and Cynognathus Assemblage Zone and Dicynodont investigations all form part of his Paleontology research activities. Richard J. Butler interconnects Clade, Monophyly, Cladistics and Pseudosuchia in the investigation of issues within Taxon.
His Archosauromorpha study incorporates themes from Osteology, Skull, Anatomy and Erythrosuchidae, Extinction event. His work focuses on many connections between Extinction event and other disciplines, such as Biodiversity, that overlap with his field of interest in Phanerozoic. His studies in Ecology integrate themes in fields like Cretaceous and Paleogene.
