| Research Abstract |
We performed field trips of Cretaceous sediments in Mongolia for five times during 2009 to 2011. The main localities are Baganuur, Khuren Dukh, Tevshiin Govi, Tugrug, Shivee Ovoo, Shine Khudak, Bayan and Erhert in southeastern side of Govi desert. The members are from Mongolian Paleontological Center, Yale University, Chicago Botanical Garden, Kanazawa University and Niigata University. We present preliminary results on the Tevshiin-Govi locality, which is a small opencast lignite mine, southwest of Ulaanbaatar. At several levels in the mine, mummified fossil plants occur matted together in compressed, lignitic, but otherwise very little altered deposits that are dominated by linear leaves of several different kinds. Cuticular details are well-preserved and reproductive structures are diverse, informative and common. Preliminary study indicates the presence of at least a dozen fossil seedplants represented by a large number of dispersed plant organs. We also performed a field survey in Malaysia with Prof. Lee, Malay University, to compare with theresults from Mongolia.
