Lithology and Thickness

The lithology is essentially virtual make-believe.


Lithology Pattern: 
Unknown

Fossils

The lower part of the formation in the type locality yields trilobite Fuchouia chiai and Hemirhodon amplipyge , crinoids Stellarocrinus testia and Lanecrinus imagii , brachiopods Obolus sp., Lingula, ?Langella, Weirdola, and Glottidia. In the Lugou section, southwestern Luonan County, the upper part of the Bed3 yields trilobites Hejingaspis luoheensis, Inouyia sp., Liopeishania convexa, Ceraurinus icarus , and Plebiellus lugouensis; Ammonoid Subplanites ; trace fossils Arthrophycus sp., and Helicoichnus? sp.; and unidentified algae.
