Two-fold-era flora

-tongued sheep-toothed flora appears in the Gonwana ancient lands of the southern hemisphere. The flora of the Rauya ancient land in the northern hemisphere gradually differentiated, forming

different plant areas in The Angara Region, Europe and the United States (Atlantic), West North America (North America) and Huaxia by the end of the Second World.。 The tongue-and-tooth plant areaincludes Australia, Antarctica, southern South America, southern Africa, the South Asian subse continent, and the yalu-Tibet region south of China. With distinctive tongue teeth (

features. Rift leaves (
Schizoneura
) are also important molecules. Lack of the northern hemisphere at this time the most prosperous scaly, reed and many ferns such as
Callipteris
). It is generally believed that the seasons in this area are clear, the temperature is low, and the wood has an annual wheel.。 The Angara regionoccupies the Soviet Union's belt between Bora, Siberia, Mongolia, northern China (including the north-east and northern Inner Mongolia and Xinjiang) and the Urals to Kazakhstan and Europe.

Annularia
) and so on. Wood has annual rounds. It is generally believed that the seasons in this area are clear and the temperature is slightly lower.。 Europe and thein the end of the Charcoal age trees-type stone pine plant scales gradually disappeared in Europe, sealing wood, wedge leaves and reeds continued until the early second generation. Sheep teeth, veined sheep teeth, and muscuous sheep teeth continued to develop in the Second Folding Age, and toothed sheep teeth and sheep teeth were also the most characteristic plants in the early 2000s in the area, which was also characterized by sheep teeth,
Lebachia
) and
Ernestiodendron
. By the end of the second day, wedge sheep teeth (
Sphenopteris
), american sheep teeth, sheep teeth, wedge ginkgo (
Sphenobaiera
), scallops (
Ullmannia
), and
Pseudovoltzia
) were distributed in the UK, Central Europe, Hungary, northern Italy and Poland.。 Europe and the United States, West North America and Huaxia region rich in scales, sealed wood, reed wood and

Has teeth sheep teeth, sheep teeth, wedge sheep teeth, pulsed sheep teeth and with sheep teeth.。 Huaxiamost of China (north to Gansu, southern Inner Mongolia, east to northeast, northwest West Tibet, North Korea and Southeast Asia). Early with the European and American sheep teeth, wheel leaves, wedge leaves, pulsed sheep teeth, teeth sheep teeth, sheep teeth, Kodak and many other species, but the appearance of valve wheel leaves (
Lobatannu-laria
), teeth leaves, woven sheep teeth (
Emplectopteris
), sheep teeth (

), Huaxia sheep teeth (
Cathaysiopteris
), single-net sheep teeth (

tonoclea
), branches (
Cladoplebis
) and many with sheep teeth. In the late stages, there were large feather sheep teeth (
Gigantopteris
), single-net sheep teeth, flap wheel leaves, fan leaves (
Rhipidropsis
) scales, etc. In the north there are palm leaves (
Psygmophyllum
), in western Gansu there are Angara molecular spoon sheep teeth, palm sheep teeth infiltration.。
