Palaeontology description
Transition from the forest period to the grassland period.
The forest only contain Pinus, Pieea Dietr and Populus.
The herbage is composed of Chenopodiaceae, Leguminous
and Artemis, indicating climate changes from warm and wet
to cold and dray. Then herbages are dominant plants,
which are composed of Gramineae, Chenopodiaceae,
Asteraceae, Leguminosae and Salix, indicate a dry climate
Forest type vegetation. The vegetation is dominated by
woody plants, which is composed of Pinus, Cupressaceae,
Juglans, Betula. The understory herbaceous plants are
dominated by Allium, Chenopodiaceae, and Compositae,
reflecting a warm and humid climate. The flora in the
Upper part of Erlang Jian Formation is dominated by Pinus,
indicating a cool and humid climate.
Forest and grassland are mainly composed of Lily.
Branch, Leguminosae, Walnut, Quercus etc.,
reflecting a humid climate at that time. The Upper
part of Hadatan Formaiton is dominated by Pieea
Dietr, Quercus and Artemisia, suggesting climiate had
changed to cold, but humid climate remained.
