Hello & FYI,
A new site about the Burgess Shale fossils and the fossil beds' location in the Canadian Rocky Mountains, curated by the Royal Ontario Museum.
"The Burgess Shale refers to a fossil-rich locality on Fossil Ridge between Wapta Mountain and Mount Field, just a few kilometres north of the small town of Field, British Columbia. Charles Walcott coined the term to describe various fossiliferous rock layers with soft-bodied preservation that he found in 1909 and 1910 and excavated for several years thereafter. The most important excavations were made within a two-metre-thick section representing a series of layers containing the most exquisitely preserved soft-bodied fossils. This section was named the "Phyllopod bed" by Walcott, in reference to the leaf-like structure of the appendages of certain abundant arthropods, including Waptia."
If you want Walcott's (1911) original Cambrian annelids paper it is available at:

Which of Walcott's fossil taxa are close to annelid clade, and which are not? You tell me.
