Macro- and microfossils of the Mount Cap Formation (Early and Middle Cambrian, Northwest Territories).
The Early–Middle Cambrian Mount Cap Formation, NWT, hosts a diverse range of exceptionally preserved fos sils. Like the celebrated Burgess Shale of British Columbia, the Mount Cap contains carbonaceous compression fossils of animals that lacked mineral ized hard parts, as well as the fully articulat...
