help Charles Doolittle Walcott FAQ
How did Charles Doolittle Walcott discover the Burgess Shale?
Walcott found important Cambrian fossils near Burgess Pass in British Columbia in 1909 and returned for repeated collecting seasons. He and his crews eventually removed tens of thousands of specimens for the Smithsonian Institution.
Why are the Burgess Shale fossils so unusual?
The deposit preserves impressions of soft-bodied animals as well as hard shells, revealing organisms rarely recorded in ordinary fossil beds. Specimens such as Marrella, Opabinia, and Anomalocaris transformed scientific views of Cambrian marine life.
Was Walcott working for the Smithsonian when he found the fossils?
Yes, he became secretary of the Smithsonian Institution in 1907 and held that position until his death in 1927. Earlier, he had directed the United States Geological Survey.
Did Walcott correctly interpret every Burgess Shale animal?
No, he often fitted unfamiliar fossils into known animal groups, an approach later researchers revised. Harry Whittington, Derek Briggs, and Simon Conway Morris reexamined many of the specimens during the 20th century.
