Leaves of a Metasequoia glyptostroboides tree in Paomu Village,Longshan County,Hunan Province (Paomu Tree) possess"Even Type"cuticles and frill-margined stomata similar to those of fossil Metasequoia by far known but different from all other living Metasequoia trees(common trees).Paomu Tree is thus hypothesized as the real"living fossil",which has been supported by preliminary DNA analyses.

Ostrich eggshell beads and fragments collected from SDG site reflect primordial art and a kind of symbolic behavior of modern humans. Based on stratigraphic data and OSL dating, these ostrich eggshell beads are probably in Early Holocene (< 10 ka BP). Two different prehistoric manufacturing pathways are usually used in the manufacture of ostrich eggshell beads in Upper Paleolithic. According to statistic analysis of the characteristics of ostrich eggshell beads, Pathway 1 is identified from these collections. In pathway 1, blanks are drilled prior to being trimmed to rough discs. They exhibit great potential for the study of the origin of primordial art and the development of ancient cultures and provide important data for studying behavioral options adopted by hominids in SDG area. In addition, they bear important implications for the origin of modern humans in East Asia.

Ediacara fossils are among the oldest, most diverse, complex macroscopic life forms in the Earth’s history. Although they have been systematically studied for nearly 60 years, their bodyplan, taphonomy, ecology and affinity are quite controversial. They were variably interpreted as sponges, cnidarians or cnidarian-grade organisms, bilateral animals, fungi or fungus-like organisms, lichens, xenophyophoran protists or vendobionts, macroscopic organisms with quilted bodyplan,

Although an abundance of 4-methyl-sterane and dinosterane thought to derive from dinoflagellates,has been detected in the Palaeogene source rocks and crude oils in the Qaidam Basin,china,no unequivocal dinoflagellate cysts have been found previously in Cretaceous-Palaeogene terrestrial deposits in this basin, including the Xiaganchaigou *** study reports on a new discovery using detailed analysis of a dinoflagellate cyst assemblage,composed solely of Subtilisphaera,from the Xiaganchaigou Formation on the north margin of the Qaidam *** biomarkers 4-methylsterane and dinosterane in the corresponding fossil-bearing beds have also been detected,further validating the dependability of dinoflagellate *** fossils provide direct evidence of the dinoflagellate contribution to Palaeogene crude oil in the Qaidam Basin and fill a long-existing gap in oil-source correlation.
