Abundant Early Cretaceous spores and pollen were found from Well Te 1 in the Wanlite Depression, Eastern Gobi Basin, Mongolia. Three assemblages have been divided, including: 1) Cicatricosisporites-Classopollis-Piceites-Piceaepollenites assemblage; 2) Perinopollenites-Cycadopites-Pinaceae-Walchiites assemblage; and 3) Laevigatosporites-Lygodiaceae-Perinopollenites assemblage. Based on the characteristics of the sporopollen assemblage, the first assemblage is assigned to the Berriasian (Early Cretaceous), but may also possibly correspend to the Late Jurassic; the second assemblage is considered to be the Berriasian—Valanginian (Early Cretaceous), and the third assemblage is equivalent to the Hauterivian—Barremian of the Early Cretaceous.
