| Outline of Final Research Achievements |
The purpose of research purpose is to recover Early Cretaceous age fossil plants from Mongolia. The focus is on mesofossils, small dispersed fossil flowers, fruits, cones, and seeds. Mesofossils are new type of plant fossils that have well preserved three dimensional structure. We have performed field trips in Tevshiin Govi, Tugrug, Shivee-Ovoo and Shine Khudag localities during 2012-2013.The fossiliferous layers belong to the Tevshiin Govi Formation, a sequence of conglomerates, sandstones, and siltstones, as well as thick coal and lignite seams, that were deposited in a terrestrial and fluvio-lacustrine system. They also contain a varied assemblage of plant remains, including copious leaves, stems, wood, roots, and reproductive structures such as cones, seeds, cupules. The goal of the research is to document seed plant diversity in central Mongolia during the Early Cretaceous.
