  • Cretaceous and Cenozoic elasmobranchs (sharks and rays) from Australia, North America and Europe but with focus on Australian mid-Cretaceous and Miocene faunas.
  • Cretaceous dinosaurs and marine reptiles from Australia and northern Europe.


  • Manages the palaeontology collection, which comprises approximately 1,500,000 specimens of vertebrate and invertebrate body fossils, plant fossils, microbialites and trace fossils.
  • High quality and scientifically significant fossil specimens are added to the Museum’s palaeontology collection through fieldwork, donations and collaborations with other institutions.

Services (to other bodies):

  • Provides advice and species identifications of fossil specimens to government.


Exhibitions and Public Programs

  • Delivers public talks on vertebrate fossils from Western Australia.
  • Developed the Dinosaur Discovery exhibit (2014, 2017) which is the most successful exhibit in the history of the WA Museum with more than 170,000 visitors in 2014 in Perth.
