In an area of the Atlas Mountains of Morocco the researchers have found another diverse (and sometimes bizarre) assemblage of soft-bodied organisms from a period not long after the Burgess Shale.───在摩洛哥的阿特拉斯山脉,研究人员发现了另一处保存有丰富的动物软体组织的的化石群,它的形成年代紧跟...
Definition The Burgess Shale biota is an assemblage of exceptionally preserved fossil organisms from rock units within the Burgess Shale Formation of the Rocky Mountains of British Columbia, Canada. It is dated at ca. 505鈥 510 Ma, within the middle part of the Cambrian Period of geologic time...
Zhu et al., 2006; Gaines, 2014), potentially as a result of the seawater chemistry, average clay mineralogy, and low oxygenation of bottom water conditions at a global scale during this time period (Butterfield, 1995; Gaines et al., 2012). The fortuitous abundance of Cambrian Konservat-...
3. The Burgess Shale came soon after a period of time known as the Cambrian explosion, when most major groups of complex animals arose over a surprisingly short period. 在寒武纪大爆发时期,主要生物种群的祖先在极短的时间内相继出现,布尔吉斯叶岩就是在这之后的不久形成的。
This commensal association is unique for a species of brachiopod, fossil or living and suggests that complex forms of symbiotic relationships were already well established by the Cambrian period. Methods All specimens come from the Cambrian (Series 3, Stage 5) Burgess Shale Formation, Walcott Quarry...

(and chemically transformed) in a rock formation called the Burgess Shale, which now lies high in the Canadian Rockies. The Burgess Shale presents an unequaled snapshot of life in the middle of the Cambrian Period, the earliest span of geological time from which we have abundant fossil ...
