It has been contentious whether the Late Carboniferous rocks, especially the late Late Carboniferous rocks were deposited in the central part of northern Qiangtang of Tibet mainly because of the lack of irrefutable biological fossils. An important progress was made by the 1:250 000 geological survey, through which the Walongshan Formation was established. Abundant Montiparus and Triticites are newly discovered. These findings inform that the unquestioned late Late Carboniferous rocks were deposited in the central part of the northern Qiangtang, Tibet.
