Taxonomic diversity, morphology and evolution of extinct crocodylians from the Cenozoic of Australia

Researcher biography

Born in North Macedonia in 1991, Jorgo Ristevski expressed interest in prehistoric life from a young age. In 2014 he obtained an undergraduate degree in archaeology at the Saints Cyril and Methodius University in Skopje, North Macedonia. In 2015 Jorgo commenced his Master of Research (MRes) postgraduate studies in vertebrate palaeontology at the University of Southampton, England. For his MRes thesis, Jorgo worked on crocodyliforms from the Cretaceous Period of the Isle of Wight under the supervision of Dr. Mark T. Young. In 2016, Jorgo obtained his MRes degree at the University of Southampton with Distinction, and was also awarded the Ocean and Earth Science MRes Prize for achieving the highest aggregate mark on a MRes program. Jorgo joined the UQ Dinosaur Lab in 2018 as a PhD student.

For his PhD project, Jorgo is investigating the taxonomic diversity, morphology and evolution of extinct crocodylians from the Cenozoic Era of Australia. Some of the methods he utilizes include comparative anatomy, data from computed tomographic (CT) scans and phylogenetic analyses. The first publication from his PhD is a revision of the Plio-Pleistocene crocodylian Pallimnarchus pollens.  Read more about this study here.

Jorgo has had field work experience in Europe (on the Isle of Wight and in Portugal) and Australia (Queensland).
