Research

Research Interests

My major research interests are centred on the evolutionary palaeobiology of dinosaurs and other extinct amniotes. In addition, I am involved in projects to investigate macroevolutionary mechanisms, the evolution of Mesozoic terrestrial ecosystems and potential biases in the fossil record. Research is concentrated in three main areas:

  • Pattern and process in macroevolution. Controls on dinosaur diversity through time; testing of plant–dinosaur co-evolutionary scenarios; clade-clade interactions; correlated progression; influence of the rock record on dinosaur and pterosaur diversity.
  • Functional morphology, palaeobiology and palaeoecology of herbivorous amniotes, principally sauropodomorph and ornithischian dinosaurs.
  • Taxonomic, systematic and faunal revisions of dinosaurs and other extinct reptiles (including lizards, plesiosaurs and ichthyosaurs) from the Middle Jurassic and Early Cretaceous of the UK, the Lower to Middle Jurassic and Early Cretaceous of the People’s Republic of China, the Lower Jurassic of South Africa and the Cretaceous of Australia and Antarctica.

Research group

My research group includes a mixture of post-doctoral and post-graduate researchers, who work on dinosaurs and other extinct reptiles. This work is primarily supported by external grants (from NERC), together with some internal NHM and university funding. Current group members are engaged in projects on the evolution of ornithischian locomotion (Dr Susannah Maidment), titanosaurian sauropod phylogeny (Rosie Barnes), ichthyosaur ontogeny and variation (Sam Bennett), and sauropodomorph cranial biomechanics (David Button).

Dr Susannah C. R. Maidment (NERC-funded Post-Doctoral Research Assistant)

Susannah’s work examines the evolution of quadrupedal locomotion in ornithischian dinosaurs. The first dinosaurs were bipedal, with forelimbs modified for grasping, but quadrupedality evolved on multiple occasions within the clade. Using a diverse set of techniques, this project aims to examine the ‘hows’ and ‘whys’ regarding the repeated evolution of quadrupedality. Along with collaborators Dr Don Henderson and Dr Karl Bates, we investigate changes to the locomotor musculoskeletal system during the evolution of quadrupedality using comparative anatomy and computational biomechanical modelling of muscle moment arms, and we test specific hypotheses regarding the causes for quadrupedality using mathematical centre of mass modelling. The results of the project will shed light on ornithischian locomotion, behaviour and palaeoecology. Susannah is also involved in the lab’s ongoing collaborative work programme to re-evalute British and Chinese dinosaur faunas.

Rosie Barnes (NERC Open CASE-funded PhD student)

Rosie (2008–) splits her time between the NHM and UCL, where she is co-supervised by Dr Paul Upchurch. Her work concerns the evolution of titanosaurian sauropod dinosaurs with particular focus on producing a new phylogeny of the group incorporating all currently known titanosaur taxa. Rosie is also interested in the evolutionary history of the group and their biogeographical distribution through time, as well as critically assessing taxonomy. A current project is the redescription of the type material of a European dwarf titanosaur (Magyarosaurus) held in the NHM collections, with colleagues from Romania and the USA.

Sam Bennett (Self-funded PhD student)

Sam (2010–) based at the NHM and Royal Holloway, University of London (co-supervised by Prof. Margaret Collinson). He is interested in Mesozoic marine reptiles and his area of study is ichthyosaurs. His project uses morphometric techniques such as Principal Components Analysis and Reduced Major Axis Regression to analyse changes in sizes and shape. Using this, a method of estimating relative age of individual specimens, regardless of size, is being established.

David Button (NERC CASE-funded PhD student)

David Button (2011–) is working on a NERC CASE funded project at the NHM/University of Bristol where he is co-supervised by Dr Emily Rayfield. His work concerns an investigation of sauropodomorph cranial mechanics and its implications on feeding utilising finite-element modelling, combined with a review of cranial arthrology of the Sauropodomorpha in consideration of the evolution of functional cranial characters associated with feeding.

Former lab members

Post-doctoral researchers

Dr Emily J. Rayfield (2002) worked on a NERC-funded project using Geographical Information Systems (GIS) to investigate the validity of Triassic vertebrate biostratigraphic hypotheses (Rayfield et al., 2005, 2009). This work was carried out while both Paul and Emily were based at the University of Oxford. Emily is now a Senior Lecturer in Palaeontology at the University of Bristol.

Dr Richard J. Butler (2006–2009) was involved in two concurrent NERC-funded projects at the Natural History Museum. The first was a two-year project investigating plant-dinosaur interactions during the Cretaceous Period (Butler et al., 2009a, b, 2010). Richard was Researcher Co-Investigator on a second short project that used CT-scanning to examine postcranial skeletal pneumaticity in Triassic archosaurs (Butler et al., 2009c). He has gone on to do additional post-doctoral work in Germany and is currently a Junior Research Group Leader at the University of Munich.

Dr Stig Walsh (2007–2008) carried out a NERC-funded project using CT-scanning to document the morphology of diapsid inner ears, and used this information to create a model for predicting ear function in extinct reptiles and birds (Walsh et al., 2009). Stig is now Senior Curator of Vertebrate Palaeontology at the National Museums of Scotland.

Past PhD students

Dr Jolyon ('Joe') C. Parish carried out his research at the University of Oxford (NERC-funded) on the phylogeny of ankylosaurian dinosaurs (2000–2005). He is currently a conservation volunteer in Wales and has just completed a major new book on the dodo and the solitaire to be publsihed by Indiana University Press.

Dr Deborah Linton (2004–2010) was based at the NHM/UCL, co-supervised by Dr Paul Upchurch (NERC CASE). Debi’s project involved detailed measurements of ornithischian limb bones to look at evolutionary trends within the group, using a morphometric approach. She is currently retraining as a museum science educator in New York.

Dr Jérémy Anquetin was funded by an NHM Postgraduate Studentship and co-supervised by Prof. Susan E. Evans (UCL). His project (2005–2009) was based on the preparation and description of a new Middle Jurassic turtle from the Isle of Skye that has significant implications for early turtle evolution. After a post-doctoral fellowship at the Muséum national d’Histoire naturelle in Paris he became a freelance technical translator, based in France.

Dr Roger B. J. Benson worked at the NHM/University of Cambridge (2005–2008), co-supervised by Dr David Norman (NERC CASE). His project was centred on revision of the historically important British dinosaur Megalosaurus and other Jurassic theropods. Following a Junior Research Fellowship at Trinity College, Cambridge, Roger is now a post-doctoral researcher at UCL.

Dr Vince Williams completed his PhD on the implications of dental microwear for understanding hadrosaur jaw mechanics (2005–2010). He was co-supervised with Prof. Mark Purnell at the University of Leicester (self-funding).

Dr Philip Mannion worked on the sauropod fossil record (2006–2009), assessing the diversity of the group through time and the potential impact of environmental and collecting biases on their observed diversity. He was a NHM/UCL student, co-supervised by Dr Paul Upchurch. Phil is currently a post-doctoral research fellow at the Museum für Naturkunde (Berlin) and Imperial College London.

Dr Mark Young studied the morphometrics and evolution of metriorhychoid crocodiles and sauropod dinosaurs at the NHM/University of Bristol (2006–2009) and was co-supervised by Dr Emily Rayfield (NERC CASE). Mark holds honorary research positions at the universities of Glasgow and Edinburgh.
