Maotianshan Shales
The Maotianshan Shales are a series of Early Cambrian deposits in the Chiungchussu Formation, famous for their '' Konservat Lagerstätten'', deposits known for the exceptional preservation of fossilized organisms or traces. The Maotianshan Shales form one of some forty Cambrian fossil locations worldwide exhibiting exquisite preservation of rarely preserved, non-mineralized soft tissue, comparable to the fossils of the Burgess Shale. They take their name from Maotianshan Hill (, Literal meaning: Hat Sky Mountain) in Chengjiang County, Yunnan Province, China. The most famous assemblage of organisms are referred to as the Chengjiang biota for the multiple scattered fossil sites in Chengjiang. The age of the Chengjiang Lagerstätte is locally termed Qiongzhusian, a stage correlated to the late Atdabanian Stage in Siberian sequences of the middle of the Early Cambrian. The shales date to ≤. The shales also contain the slightly younger Guanshan biota from Malong District in Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chuandianella
''Chuandianella ovata'' is an extinct bivalved arthropod that lived during Cambrian Stage 3 of the Early Cambrian (about 520 to 516 million years ago). It is the only species classified under the genus ''Chuandianella''. Its fossils were recovered from the Chengjiang Biota in Yunnan, China. Taxonomy It was originally described in 1975 under the "ostracod"-like genus '' Mononotella'', as ''Mononotella ovata''. In 1991, the paleontologists Xian-Guang Hou and Jan Bergström reclassified it under the new genus ''Chuandianella'' when additional discoveries of more complete specimens made its resemblance to '' Waptia fieldensis'' more apparent. In 2004, paleontologist Jun-Yuan Chen tentatively transferred it to the genus ''Waptia''. However, ''C. ovata'' had eight abdominal somites in contrast to five in ''W. fieldensis''. Its limbs were biramous and were undifferentiated, unlike those of ''W. fieldensis''. Other authors deemed these differences to be enough to separate it from '' ...

Forfexicaris
''Forfexicaris valida'' is a species of Lower Cambrian arthropod, the only species in the family Forfexicarididae. It is known from only two specimens from the Maotianshan shale '. Description ''F. valida'' had a bivalved carapace, like that seen in ostracod crustaceans, which was long and high. It had a pair of stalked eyes, and a pair of great appendage Great appendages are claw-like appendages which attach to the heads of the "great appendage arthropods", a name usually refers to Megacheira, a class of extinct arthropod characterized by a pair of "short-great appendages" bearing in front of the ...s, which closely resemble those of '' Occacaris''.

Ercaicunia
''Ercaicunia'' is genus of bivalved Cambrian arthropod from the Chengjiang biota of Yunnan, China. It contains a single species, ''E. multinodosa'' that was described by Luo et al. in 1999. The total length of the body ranges from . The bivalved carapace covered about a third of the total body-length, and has up to six serrations on its forward edge. The head has a pair of large uniramous antennae, as well as a smaller pair of secondary antennae, as well as pair of mandibles and maxillae. The trunk has 16 pairs of biramous appendages. Specimens were CT scanned in 2019, which suggested it to be a stem-group crustacean. Other subsequent studies have recovered it as a member of Hymenocarina, which contains other bivalved Cambrian arthropods.

''Dongshanocaris'' is genus of Cambrian arthropod known for being a member of the Chengjiang biota, containing the single species ''D. foliiformis''. It was described by Hou and Bergstrom in 1999.

Dianchia
''Leanchoilia'' is an megacheiran arthropod known from Cambrian deposits of the Burgess Shale in Canada and the Chengjiang biota of China. It was about long and had long, whip-like feelers mounted on frontal arm-like appendages. Its internal organs are occasionally preserved within the substrate in three dimensions. Seven species are tentatively accepted today: ''L. superlata'' (the type species), ''L. persephone'' and ''L. protogonia'' from the Burgess Shale, ''L. illecebrosa'' and ''L. obesa'' from the Chengjiang biota, 'L. robisoni'' from Kaili, and ''L.''? ''hanceyi'' from the Spence Shale. ''L. superlata'' and ''L. persephone'' may however be examples of sexual dimorphism. 55 specimens of ''Leanchoilia'' are known from the Greater Phyllopod bed The Phyllopod bed, designated by USNM locality number 35k, is the most famous fossil-bearing member of the Burgess Shale fossil '' Lagerstätte''.
