Definition of Burgess Shale in English:
A bed of shale exposed in the Rocky Mountains in British Columbia, Canada. The bed, dated to the Cambrian period (about 530 million years ago), is rich in well-preserved fossils of early marine invertebrates, many of which represent evolutionary lineages unknown in later times.
- The best-known of these sites is the legendary Burgess Shale in the British Columbian Rocky Mountains.
