| Abstract: | During 1∶250 000 regional geological surveys and special-subject research on
the Triassic, a group of plant fossils were taken from Xionglongxi, Xinlong County, and
Rejia, Baiyu County, Sichuan Province. They include 15 genera and 20 species, of which two
species are new and one genus was first found in China. These fossils not only enrich the
content of the plant fossil assemblage in the study area but also provide an important
paleontological basis for the determination of stratigraphic ages, stratigraphic
correlation with neighboring areas and reconstruction of the sedimentary environment. |
