| Paleozoic Era | Cambrian Lagerstätte |
| Timescale | Tommotian Biota |
Most Cambrian organisms are only known from their hard parts, but a number of exception sites preserve soft-tissue impressions. Here is a partial listing of Cambrian Lagerstätte
| Some Cambrian Lagerstätten | Location | Period/Epoch | Age of Deposits | Type of organisms |
| Sirius Passet | , | Early Cambrian ( Atdabanian ) | 521 million years old | mostly soft-bodied arthropods, also annelids and large priapulids; few taxa with shelly skeletons |
| Chengjiang | Yunnan Province, China | Early Cambrian ( Latest Atdabanian or earliest Botomian? ) | 519 million years old | many different groups well represented |
| Burgess Shale | British Columbia, Canada | Middle Cambrian (Amgan) | 507 million years old | many different groups well represented |
| Orsten | Sweden | Late Cambrian | 495 million years old | various tiny (mostly larval) arthropods |
