Burgess ShaleThe Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. It is famous for the exceptional preservation of the soft parts of its fossils. At c.505 million years old (middle Cambrian), it is one of the earliest fossil beds containing soft-part imprints. The rock unit is a black shale and crops out at several localities near the town of Field in Yoho National Park and the Kicking Horse Pass.

LagerstätteA Fossil-Lagerstätte (German pronunciation: – from 'storage, lair' and 'place'; pl.Lagerstätten) is a sedimentary deposit that preserves an exceptionally high amount of palaeontological information. Konzentrat-Lagerstätten preserve a high concentration of fossils, while Konservat-Lagerstätten offer exceptional fossil preservation, sometimes including preserved soft tissues.
ShaleShale is a fine-grained, clasticsedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers (laminae) less than one centimeter in thickness. This property is called fissility. Shale is the most common sedimentary rock.

Chinese languageChinese (spoken: simplified Chinese: 汉语; traditional Chinese: 漢語; pinyin: Hànyǔ, written: 中文; Zhōngwén) is a collection of language varieties containing almost all Sinitic languages except Macro-Bai languages, natively spoken by the Han Chinese and some ethnic minorities in Greater China, as well as by communities of the overseas Chinese.Traditional Chinese charactersTraditional Chinese characters are one of two standardized character sets used to write the Chinese language, with the other being simplified characters. Traditional characters predominated in written Chinese, the historical lingua franca of East Asia, until the mid-20th century. Today, they are used in Taiwan, Hong Kong, and Macau, as well as in most overseas Chinese communities outside of Southeast Asia.

Evolutionary faunaThe concept of the three great evolutionary faunas of marine animals from the Cambrian to the present (that is, the entire Phanerozoic) was introduced by Jack Sepkoski in 1981 using factor analysis of the fossil record. An evolutionary fauna typically displays an increase in biodiversity following a logistic curve followed by extinctions (although the Modern Fauna has not yet exhibited the diminishing part of the curve).
