Postdoctoral Research Scholar

Education

  • Ph.D. in Biological Sciences, Graduate School of Science, Hokkaido University, 2019
  • M.Sc. in Biological Sciences, National University of Mongolia, 2011
  • B.Sc. in Biological Sciences, National University of Mongolia, 2005

Research Interests

After Chinzorig received his B.S., he began his career in the field of Paleontology at the Institute of Paleontology and Geology in Mongolia. One of his primarily researches is a major Late Cretaceous coelurosaurian dinosaur groups, ornithomimosaurs (Theropoda: Ornithomimosauria). His interests in this group are not only focus on the skeletal morphological disparities, variations, phylogeny, distribution and diversity of mainly Asian and North American taxa, but it also interests of understanding a paleoecological and paleobiographical implications of ornithomimosaur dinosaurs in general on the basis of their morpho-anatomical skeletal remains.
