Miliang (Devonian to of China)

Where: Hubei, China (33.3° N, 109.5° E: paleocoordinates 8.8° S, 114.5° E)

• coordinate based on political unit

When: Tiaomachien Formation, Givetian to Givetian (387.7 - 372.2 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; mudstone and sandstone

• Rhizomes and branches are in organic connection, indicating that the sediments were autochthonously deposited in quiet water.
• Some beds consist mainly of quartzose sandstones of the Late Devonian age based upon geological evidence. These beds rest unconformably on a layer of sandy mudstones of Middle Silurian age. The fossiliferous beds, about nine meters above the base of the Upper Devonian stratum, are composed mainly of mudstones.
