EARLY PALEOZOIC LIFEAdvent of the Metazoans
Multicellular organisms begin to become commonin fossil record of Neoproterozoic
Fossils found on every continent
Fossils are impressions of soft bodied organisms
Metazoans are multicellular organisms the possessmore than one kind of cell and cells are organized into organs and tissue.

THE BURGESS SHALE
Part of the Cambrian Stephen FormationMt. Wapta, near Field, BCFirst studied by Charles D. Walcott beg. 1909
Secretary of Smithsonian InstitutionLater studied by Harry B. Whittington in 1960s

Lagerstätten [meaning "(fossil) deposit places" in German] are geological fossil deposits that are rich with varied, well-preserved fossils, representing a wide variety of life from a particular era.
These spectacular fossil deposits represent an amazing "snapshot" in time.
Ediacaran, Burgess and Chengjiang deposits are good examples.
