Kobayashi Yoshitsugu is a Japanese paleontologist, specialising in ornithomimosaurs, therizinosaurs from Mongolia and China, and comparing dinosaur diversities between North America and Asia.
Yoshitsugu grew up in Fukui in Japan, and collected ammonite fossils as a past time. He moved to the United States in the early 90s for his schooling, and got his Bachelor's degree from the University of Wyoming in 1995. He obtained his Master's degree in 1998, and his PhD in 2004, both from the Southern Methodist University in Texas. Yoshitsugu is currently an associate professor in the Science Department of Natural History Sciences at Hokkaido University in Japan.
Yoshitsugu is also an Invited Associate Professor at the Osaka University Museum in Japan, an Associate Editor of the Journal of the Paleontological Society of South Korea.
In the year 2000, he helped prepare for the opening of the Fukui Prefectural Dinosaur Museum. In 2005 he moved to Hokkaido to work at the University there, seeing the potential for a large number of finds in the future due to the exposed Cretaceous rock.
He has described or discovered at least six dinosaurs, including Quipalong henanensis. Through work, he has traveled to Canada, China, Mongolia, South Korea, and the United States.
